Podcast Episode 125: The Black Hole Conspiracy


Black holes: Are these dense,
Massive objects for realz, or
Are they just Sci Fi?

This is a bit different from a straight-up old-school “debunking” episode where the emphasis is more on the process of science and process of elimination rather than solid, cannot-be-dismissed evidence for something. That’s because, by definition (we think), black holes cannot be directly observed. That’s why I use a part of a blog post by Mike Bara as a very rough outline to go through some of the theoretical reasons for why we think black holes exist and then some of the observational evidence from material interacting with the theoretical objects.

This episode continues the Logical Fallacies segment and introduces you to the Burden of Proof fallacy. Which is a tricky one. There are also some old stalwarts like Argument from incredulity, argument from ridicule, ad hominem, straw man, and argument from authority.

And, for the first time in what seems like a year, there’s Q&A!!!

I’m still doing my listening “research” for the Hale-Bopp episodes, which is looking like there’s so much material that I may turn it into a three-parter. We’ll see. Hard to say at this point. It’s slated to be the next episode, but I may have to postpone that if I haven’t finished listening in time, and I’ll do a different episode instead. I’m also trying to line up at least two future interviews, but given past experience, I’m loathe to announce them before they’re recorded.

Podcast #64: Quantum Nonsense


Episode 64: Quantum Nonsense, has been posted. It’s a combination of some new material and two previous blog posts. The topic is basically an intro to quantum mechanics and a discussion of how it is used and abused by pseudoscientists today. And, I branch away from Coast to Coast for other sources of audio clips! There’s also a puzzler and an addendum to the previous episode.

Is Skeptiko Host Alex Tsakiris a Willful Deceiver?


Introduction

I like to look at my stats page on WordPress to see what sites link up to me, how people get here. I thoroughly enjoy when RationalWiki links to me, using me as a source, and I recently found out that a new Alex Tsakiris page has an entire section devoted to my analysis of where Alex goes wrong in his attempts to argue scientifically.

I also saw that a blog, much much more popular than mine by Alex’s latest guest was linking to me – a blog by Dr. Jerry Coyne, an “outspoken atheist” according to how Alex bills him. In perusing the comments on that blog (which is where someone had linked to one of my previous posts), I noticed a claim that Alex’s transcripts were deliberately altered to change the guest’s meaning.

Update 2 days later: The errors referred to below have now been corrected.

On Transcripts

Now, a bit of explanation — Alex, on his Skeptiko website, provides transcripts of his interviews for every episode. In fact, I have used them before though I’ll note that in the body of every post where I talk about Alex, I have written my own transcript of the episode.

Several podcasts provide transcripts (my own, Skeptoid, Astronomy Cast, just to name a few), and I think they’re a valuable service. I understand that making transcripts of an interview is somewhat different than making one for a podcast episode that you’ve scripted out (which is why I don’t do transcripts of my own interview episodes). When I do transcripts, I simply copy-and-paste from what I wrote for the episode into the web page.

Evidence of Fraud?

However, it appears as though Alex – or whomever does his transcripts – has willfully and without notice altered his guest’s words.

Here is a screenshot that I took on Friday evening, February 17, 2012, of the episode with Dr. Coyne, #161

Alex Tsakiris' Transcript for Skeptiko Episode #161

Alex Tsakiris' Transcript for Skeptiko Episode #161

For word-searchability, here is the quote, copied-and-pasted from Alex’s site:

Alex Tsakiris: I’m just saying if they’re saying at the fundamental level of physics non-local theories are incompatible with what we observe, then I think it calls into question the things that we’re talking about in terms of Materialism, Determinism. Isn’t that the direct implication of what they’re saying?

Dr. Jerry Coyne: No! No, because they’re talking about what happens in a very, very tiny micro level. It does not mean that you can’t predict what happens when billiard balls hit each other on a billiard table for which quantum mechanics is perfectly applicable. It’s as if you’re saying we can’t play billiards and we can’t shoot rockets to the moon because of this stuff that happens on a micro level.

The fact is that assuming that these phenomena apply on most of the levels of reality that we deal with renders everything wrong is simply incorrect. For most micro-phenomenon you’re turning to quantum mechanics. It works fine. And in terms of evolution I don’t see how this quantum mechanics affects evolution at all. I mean, maybe it can affect mutation. You said that these people say that but that turned out to be something you made up. I don’t see how it can and even if it did it would not by any means render mutations non-random in the way that evolution has to mean that they’re random.

Reading that, as someone with a physics background Dr. Coyne is mistaken. Billiard balls hitting each other is obviously a Newtonian issue, otherwise if classical mechanics could not explain what goes on in a basic game of pool, then Quantum Mechanics would have been developed centuries before it was.

In the second paragraph, the statement about QM applying to micro-phenomenon is mostly correct (I’d argue nano, but whatever), though it doesn’t really lead logically into what he says next about QM not affecting evolution. It’s a totally new idea.

Tonight, I listened to the episode. At 12 minutes 58 seconds, I started to record my own transcript of what Dr. Coyne stated:

Dr. Jerry Coyne: No! No, because they’re talking about what happens in a very, very tiny micro level. It does not mean that you can’t predict what happens when billiard balls hit each other on a billiard table for which Newtonian mechanics is perfectly applicable. I mean, it’s as if you’re saying that we can’t play billiards or we can’t shoot rockets to the moon because of this stuff that happens on a micro level.

The fact is that assuming that these phenomena apply on most of the levels of reality that we deal with renders everything wrong is simply incorrect. I mean, for most macro-phenomenon, Newtonian or classical mechanics works fine. Um, and in terms of evolution I don’t see how this quantum mechanics affects evolution at all. I mean, maybe it can affect mutation. You said that these people say that but that turned out to be something you made up. Um, I don’t see how it can and even if it did it would not by any means render mutations non-random in the way that evolution has to mean that they’re random.

Notice a difference? Yeah. Whoever wrote the transcript on Alex’s site changed out “Newtonian mechanics” for “quantum mechanics” when talking about billiards, and changed “macro-phenomenon, Newtonian or classical mechanics works fine” to “micro-phenomenon you’re turning to quantum mechanics. It works fine.”

‘Cause, you know, they sound so similar.

Someone even has pointed this out to Alex on his comments for that episode:

Correcting Alex's Transcript for Skeptiko Episode #161

Correcting Alex's Transcript for Skeptiko Episode #161

There may be other examples — I chose not to listen to the entire hour-long episode with an eye on Alex’s transcript. Let me know if there are other examples. I really don’t know what to think on this one. I like to give people the benefit of the doubt. I was hoping that despite my two very extensive blog posts on Alex (here and here) that Alex just had his head down a rabbit hole, he’d drunk the Kool-Aid®, he was a true believer who sorta meant well and was blinded by his beliefs, etc. This, however — changing your own guest’s words in a transcript — changes things.

Hounding Alex on the Forum

Alex has a forum thread for this episode. On it, Alex was notified of the problems in the transcript here:

Where are Transcript Corrections

Where are Transcript Corrections

Alex acknowledged them about an hour later, and claimed he corrected them here:

Alex Acknowledging Corrections

Alex Acknowledging Corrections

So I went back to the page for the episode, reloaded it, cleared the cache and reloaded it and … the errors are still there. And as of adding this sentence, 19 hours later, the errors are still there. I’m not sure what Alex meant by “all better.”

Final Thoughts – You Make Up Your Own Mind on This One

I’m not saying these are huge issues and evidence of a conspiracy nor anything like that. It’s possible that in an hour-long program and longer spent writing a transcript, errors will happen. I’m somewhat willing to extend the benefit of the doubt on this. But when an error is pointed out and then is said to have been corrected but it hasn’t been, that brings it to a new level.

So, what do you think, folks?

And I’ll note that if the transcript ever does get updated (and someone lets me know – I’m only going to check it for another day or so), then I’ll of course update this post to let people know.

Skeptiko Host Alex Tsakiris on Monster Talk / Skepticality, and More on How to Spot Pseudoscience


Introduction

A few weeks ago, I learned that the popular Monster Talk podcast would be interviewing Skeptiko podcast host, Alex Tsakiris. They ended up later posting it instead on their Skepticality podcast feed, and the interview also was episode 153 of Skeptiko; it came out about two weeks ago. The interviewers from Monster Talk are Blake Smith, Ben Radford, and Karen Stollznow (the last of whom I have the pleasure of knowing). Got all that?

If the name Alex Tsakiris sounds familiar but you can’t quite place it and you’re a reader of this blog, you probably recognize it from the two previous posts I’ve written about him on this blog. The first was on the purpose of peer-review in science because Alex (among others) were talking about how peer-review was a flawed process and also that you should release results early without having a study completed.

Fourteen months later, I wrote another post on Alex, this one being rather lengthy: “Skeptiko Host Alex Tsakiris: On the Non-Scientifically Trained Trying to Do/Understand Science.” The post garnered a lot of comments (and I’ll point out that Alex posted in the comments and then never followed-up with me when he said he would … something he accuses skeptics of not doing), and I think it’s one of my best posts, or at least in the top 10% of the ~200 I’ve written so far.

This post should be shorter than that 2554-word one*, despite me being already in the fourth paragraph and still in the Introduction. This post is further commenting on not the actual substance of Alex Tsakiris’ claims, but rather on the style and format and what those reveal about fundamental differences between real scientists and pseudoscientists. I’m going to number the sections with the points I want to make. Note that all timestamps below refer to the Skeptiko version.

*After writing it, it’s come out to 3437 words. So much for the idea it’d be shorter.

Point 1: Establishing a Phenomenon Before Studying It

About 8 minutes into the episode, Karen talks with Alex about psychics, and Alex responds, “If you’re just going to go out and say, as a skeptic, ‘I’m just interested in going and debunking a psychic at a skeptic [sic] fair,’ I’m gonna say, ‘Okay, but is that really what you’re all about?’ Don’t you want to know the underlying scientific question?”

Alex raises an interesting point that, at first glance, seems to make perfect sense. Why belittle and debunk the crazies out there when you could spend your valuable time instead investigating the real phenomenon going on?

The problem with this statement – and with psi in general – is that it is not an established phenomenon that actually happens. Psi is still in the phase where it has yet to be conclusively shown to exist under strictly controlled situations, and it has yet to be shown to be reliable in its predictions/tenants. By this, I mean that psi has yet to be shown to be repeatable by many independent labs and shown to be statistically robust in its findings. I would note the obvious that if it had been shown to be any of these, then it would no longer be psi/alternative, it would be mainstream.

Hence, what the vast majority of skeptics are doing is going out and looking at the very basic question of does the phenomenon exist in the first place? If it were shown to exist, then we should spend our time studying it. Until then, no, we should not waste time trying to figure out how it happens. This really applies to pretty much everything, including UFO cases. In that situation, one has to establish the validity by exploring the claims before one looks at the implications, just like with alleged psychics.

A really simple if contrived example is the following: Say I want to study life on Io, a moon of Jupiter. I propose a $750 million mission that will study the life there with cameras, voice recording, chemical sensors, the works. I would propose to hire linguists to try to figure out what the beings on Io are saying to the probe, and I’d propose to hire biologists to study how they could survive on such a volcanic world. NASA rejects my proposal. Why? Because no one’s shown that life actually exists there yet, so why should they spend the time and money to study something they don’t know is actually there? And, not only that, but Io is so close to Jupiter that it’s bathed in a huge amount of radiation, and it is so volcanically active that it completely resurfaces itself every 50 years, making even the likelihood of life existing there very slim.

Point 2: Appeal to Quantum Mechanics

I’ll admit, I have a visceral reaction whenever I hear a lay person bring up quantum mechanics as evidence for any phenomenon not specifically related to very precisely defined physics. At about 12.5 minutes into the episode, Alex states quite adamantly that materialism (the idea that everything can be explained through material things as opposed to an etherial consciousness being needed) “is undermined by a whole bunch of science starting with quantum mechanics back a hundred years ago … .”

It’s really simply basically practically and all other -ly things untrue. Alex does not understand quantum mechanics. Almost no lay person understands quantum mechanics. The vast majority of scientists don’t understand quantum mechanics. Most physicists don’t understand quantum mechanics, but at least they know to what things quantum mechanics applies. Alex (or anyone) making a broad, sweeping claim such as he did is revealing more their ignorance of science than anything else.

Unless I’m mistaken and he has a degree in physics and would like to show me the math that shows how quantum mechanics proves materialism is wrong. Alex, if you read this, I’d be more than happy to look at your math.

You will need to show where quantum mechanics shows that consciousness – human thoughts – affect mater at the macroscopic level. Or, if you would like to redefine your terms of “consciousness” and “materialism,” then I will reevaluate this statement.

(For more on quantum mechanics and pseudoscience, I recommend reading my post, “Please, Don’t Appeal to Quantum Mechanics to Propagate Your Pseudoscience.”)

Point 3: Appeal to Individual Researchers’ Results Is a Fallacy

A habit of Alex is to relate the results of individual researchers who found the same psi phenomenon many different times in many different locations (as he does just after talking about quantum mechanics, or about 45 minutes into the episode where they all discuss this, or throughout the psychic detective stuff such as at 1:30:30 into the episode). Since I’ve talked about it at length before, I won’t here. Succinctly, this is an argument from authority, plain and simple. What an individual finds is meaningless as far as general scientific acceptance goes. Independent people must be able to replicate the results for it to be established as a phenomenon. The half dozen people that Alex constantly points to does not trump the hundreds of people who have found null results and the vast amount of theory that says it can’t happen (for more on that, see Point 6).

For more on this, I recommend reading my post on “Logical Fallacies: Argument from Authority versus the Scientific Consensus” where I think I talk about this issue quite eloquently.

It’s also relevant here to point out that a researcher may have completely 100% valid and real data, but that two different people could reach very different conclusions. Effectively, the point here, which is quite subtle, is that conclusions are not data. This comes up quite dramatically in this episode about 22.3 minutes in when discussing the “dogs that know” experiment; in fact, my very point is emphasized by Ben Radford at 24 min 05 sec into the episode. For more on this sub-point, I recommend reading my post from last year‘s Point 1.

Point 4: Investigations Relying on Specific Eyewitness Memories Decades After the Fact = Bad

The discussion here starts about 36 minutes into the episode, stops, and resumes briefly about 50 minutes in, and then they go fully into it at 1 hour 13 minutes in*. For background, there is a long history of Alex looking into alleged psychic detectives, and at one point he was interviewing Ben Radford and they agreed to jointly investigate Alex’s best case of this kind of work and then to hash out their findings on his show. This goes back to 2008 (episode 50), but it really came to a head with episode 69 in mid-2009 where they discussed their findings.

Probably not surprisingly, Alex and Ben disagreed on the findings and what the implications were for psychic detectives (Nancy Weber in this case). If you are genuinely interested in this material, I recommend listening to the episodes because there is much more detail in there than I care to discuss in this quickly lengthening post. The basic problems, though, were really two-fold — Ben and Alex were relying on police detectives remembering specific phrases used by the alleged psychic from a case almost 30 years old (from 1982), and they disagreed on what level of detail counted as a “hit” or “miss.”

For example, when Ben talked with the detectives, they had said the psychic told them the guy was “Eastern European” whereas they had separately told Alex that she had told them the guy was “Polish.” Alex counted it as a hit, Ben a miss. I count it as a “who knows?” Another specific one they talk about in this interview is “The South” versus “Florida” with the same different conclusions from each.

To these points, both scientists and skeptics (and hopefully all scientists are appropriately skeptical, as well) I think can learn a lot when looking into this type of material.

First, I personally think that this was a foolish endeavor from the get-go to do with an old case. Effectively every disagreement Ben and Alex had was over the specific phrasing which, unless every single thing the alleged psychic says is recorded, you are never going to know for sure what she said. Human memory simply is not that reliable. That is a known fact and has been for many years (sources 1 and 2, just to name a couple). Ergo, I think the only proper way to investigate this kind of phenomenon where you have disagreements between skeptics and other people is to wait for a new case and then document every single part of it.

Second, one needs to determine a priori what will count as a hit or miss (“hit” being a correct prediction, “miss” being wrong). In the above example, if they had agreed early on that Nancy Weber only needed to get the region of the planet correct, then it would be a hit. If she needed to get the country (first example) or state (second example) correct, it would be a miss under what the detectives told Ben. This latter point is the one that is more relevant in scientific endeavors, as well. Usually this is accomplished through detailed statistics in objective tests, but in qualitative analyses (more relevant in things like psychiatric studies), you have to decide before you give the test what kinds of answers will be counted as what, and then you have to stick with that.

It should be noted that hits vs. misses was not the actual crux of the disagreement, however. It was the level of specificity the psychic claimed (“Polish”) versus what the detectives told Ben they remembered (“Eastern European”), and then the broader picture to how well that information will help solve a case.

I actually encounter the same thing when grading essays. This is one reason why teachers in science classes like multiple-choice questions more than essays (besides the time it takes to grade): It’s much more quantitative to know the answer is (A) as opposed to parsing through an essay looking for a general understanding of the question being asked.

*I’ll warn you that this goes on for about a half hour and it’s somewhat difficult to listen to with all the shouting going on. If you’re scientifically/skeptically minded, listening to this is going to make you want to smack Alex. If you’re psi/alternative minded, listening to this is going to make you want to smack Ben. This is why I try not to get into the specifics of the exact case but rather point out the process and where the process is going wrong here.

Point 5: Confusing Different Causes for a Single Effect

About 41 minutes into the episode and then for several minutes on, the conversation turned to the idea that psychics help with the grieving process. The reaction from me (and then the hosts) was pretty much, “Duh!” As Blake points out just before the 43 minute mark, “How many times did the [psychic] say, ‘Oh gee! That person’s in Hell!'” Thus, probably, not helping the grieving process.

The conversation steered along the lines of the three hosts of Monster Talk trying to point out that yes, the effect of the alleged psychic talking with the grieving person is that the grieving person felt better. But was the cause (a) because the person was actually psychic, or (b) because the person was telling the grieving people what they wanted to hear that their loved one was happy and still with them and they would join them when they died?

Alex obviously is of the former opinion (after pulling out yet another argument from authority that I talked about in Point 3 above). The others are of the latter. But the point I want to pull from this is something that all scientists must take into account: If they see an effect, there could be causes other than or in addition to their own preferred explanation. That’s really what this case that they talk about boils down to.

For example, we want to know how the moon formed. There are many different hypotheses out there including it formed with Earth, it was flung off Earth, it was captured, it was burped out, or a Mars-sized orbit crashed into Earth and threw off material that coalesced into the moon. I may “believe” in the first. Another person may in the last. We both see the same effect (the moon exists and has various properties), but how we got that effect probably only had one cause. Which one is more likely is the question.

Point 6: It’s Up to the Claimant to Provide the Evidence

I know I’ve discussed this before, but I can’t seem to find the post. Anyway, this came up just before the 52 minute mark in the episode, that Alex frequently states it’s up to the debunkers to debunk something, not for the claimant to prove it. (To be fair, in this particular interview, Alex kinda says he never said that at first, he only says it when it’s a paradigm shift kinda thing that’s already shifted … which it so has not in this case. But then he does say it …)

Blake: I think most skeptical people believe that whenever you’re making a claim that you have the burden of proof every time. And it never shifts …

Alex:… And they’re wrong because that’s not how science works. Science works by continually asking hard, tough questions and then trying to resolve those the best you can.

I’m really not sure where Alex gets this first sentence (the second sentence is correct, but it and the first are not mutually exclusive). It’s simply wrong. In no field is this a valid approach except possibly psi from Alex’s point of view. If you make a claim, you have to support it with evidence that will convince people. If I say I can fly, it shouldn’t be up to you to prove I can’t, it should be up to me to prove I can. It’s that simple. And Alex gets this wrong time after time.

This is further evidence (see Point 2 above) that Alex has no actual concept of science and how it works. And before you accuse me of ad hominems, I’m stating this in an objective way from the data — his own statements that have not been quote-mined (go listen to the episodes yourself if you don’t believe me).

But it continues:

Ben: So who does have the burden of proof?

Alex: Everybody has the burden of proof and that’s why we have scientific peer-reviewed journals, the hurdles out there that you have to overcome to establish what’cha know and prove it in the best way you can. It gets back to a topic we kinda beat to death on Skeptiko and that’s this idea that also hear from skeptic [sic], ‘Extraordinary claims require extraordinary proof.’ Well of course that’s complete nonsense when you really break it down because scientifically the whole reason we have science is to overcome these biases and prejudices that we know we have. So you can’t start by saying ‘Well, I know what’s extraordinary in terms of a claim, and I know what would be extraordinary in terms of a proof,’ well that’s counter to the idea of science. The idea of science is it’s a level playing field, everybody has to rise above it by doing good work and by publishing good data.

(Ben Radford corrects Alex on this point about 54.7 minutes into the episode; feel free to listen, but also know that the points he makes are not the ones I do below. Well, maybe a bit around 56 minutes.)

I know I’ve talked about this before, but not in these exact terms. What Alex is talking about – and getting wrong – without actually realizing it is how a hypothesis becomes a theory and the lengths one has to go to to overturn a theory. That’s what this nugget boils down to.

If you’re not familiar with the basic terminology of what a scientist means by a fact, hypothesis, theory, and law, I recommend reading one of my most popular posts that goes into this. The issue at hand is that it is effectively established theory that, say, people cannot psychically communicate with each other (yes, I know science can’t prove a negative and there’s no Theory of Anti-Psi, but go with me on this; it’s why I said “effectively”). Even if it’s not an exact theory, there are others that are supported by all the evidence that show this isn’t possible nor plausible.

Ergo, to overturn all those theories that together indicate psi can’t happen, you have to have enough convincing and unambiguous data to (a) establish your phenomenon and (b) explain ALL the other data that had backed up the previous theories and been interpreted to show psi is not real.

This is summarized as, “Extraordinary claims require extraordinary evidence.” That’s the phrase, not “proof,” which in itself shows yet again that Alex misses some fundamental tenants of science: You can never prove anything 100% in science, you can only continue to gather evidence to support it. “Proof” does not exist, just like “truth,” as far as science is concerned.

Final Thoughts

Well, this post ended up longer than I had initially planned, and it took several hours not the least of which is because I listened to the episode twice and it’s almost two hours long. I hope that through this I’ve been able to illustrate several points that you and everyone needs to watch out for when evaluating claims.

To quickly recap:

  1. You need to establish that a phenomenon exists before studying it.
  2. Don’t appeal to quantum mechanics unless you actually know what quantum mechanics is.
  3. A single or small group of researchers’ results are not convincing, no matter who they are.
  4. If you want to study something that supposedly happens every day, don’t choose an example that’s 30 years old.
  5. A single effect can have multiple or different causes, including one that you don’t like.
  6. The person making the claim has the burden of evidence … always.

In the end, I’ll admit that this was personally hard to listen to in parts. I took issue with Alex constantly refusing to admit certain things like the detectives saying one thing to him and another to Ben and saying Ben was lying about it and that he should say (what he didn’t say) to the detectives’ faces. That was just hard to listen to. Or Alex’s refusal to directly answer some questions in ways that would have made a politician proud. Another point that was hard to listen to but oh so sweet in the end was Alex claiming that Karen had invited him on but Karen said that Alex had invited himself on. Alex insisted that wasn’t true and said Karen was wrong and he had the transcript … and then a few seconds later the transcript was read and Alex clearly had invited himself onto their show.

But, those are my personal and more emotional observations after listening to this. Do those change what we can learn about the scientific process and where pseudoscientists go wrong? No. Alex Tsakiris continues to unwittingly provide excellent examples of how not to do science.

With Relativity and Quantum Mechanics, Is Newtonian Mechanics Irrelevant?


Introduction

I listen to a lot of paranormal and anti-science material. I do it to keep up with what “the other side” thinks and does. And get blog ideas. One such is the radio show / podcast is entitled “Dreamland” which “takes you to the edge of reality.” Or just past it altogether.

The show is run by Whitley Streiber with occasional guest hosts Anne Streiber (his wife), Jim Marrs (a huge conspiracy nut perhaps best known for his “work” on the JFK assassination), Marla Frees, and sometimes others.

Enough background — this post is about a side comment made by the Mrs. Streiber on the just-out Dreamland episode, “The God Theory.” In actuality, I had little issue with the bulk of the episode, it’s really Mrs. Streiber’s remark early on that got me and is the subject of this post. It also delves a bit into the nature of science.

The Remark

This statement starts around 1 min 35 sec into the episode.

Mrs. Streiber: “I know a tiny bit about quantum physics. I have a layman’s understanding of it which we’re all going to have to have eventually because the type of science most of us were taught in school – Newtonian – is not relevant anymore, it’s not the way the world works.”

Epsilon

I heard a talk given by the “Bad Astronomer,” Phil Plait, a few months ago, entitled something along the lines of, “The Final Epsilon.” Epsilon, actually epsilon (lower-case), is the Greek letter that looks like ε. In physics and math, ε is used to mean “a very little bit.” For example, I wrote a recipe that calls for 1 part butter, 4+ε parts peanut butter, and 8-ε parts powdered sugar. In other words, it needs a little bit more than 4 parts peanut butter, and a little less than 8 parts powdered sugar.

Dr. Plait’s thesis was effectively, in skepticism, what is our “final ε?” In science, we can never prove anything 100%. We can never disprove something 100%. Similarly, in modern scientific skepticism, we can never disprove someone’s claim 100%. Despite every debunked alleged psychic, we can never prove 100% that psychic powers are not possible.

The discussion during Dr. Plait’s talk was, though, at what point do we say for all practical purposes we have disproved something? After debunking dozens upon dozens of astrologers and their claims and their methods, even though scientifically I can’t say astrology is 100% Taurus (see what I did there?), I could say it’s 99.9999% bull. And if I’m so close, just 0.0001% away from absolute Truth, am I willing – for all practical purposes – to say that that is my ε and I have effectively proven it to be false?

Tying These Two Together

Now you might be thinking, “Gee, that’s fascinating and I love me some good calculus, but what does this have to do with whether Newton is okay or if I have to learn QM?” I’m glad you asked.

Another point that Phil mentioned in his talk is that the concept of the “final ε” is just as applicable to how we view the world through physics. Newton’s Law of Gravity works in our every-day world. It very accurately describes what will happen if I drop a screaming baby who won’t stop screaming in the middle of the night in the apartment above me bowling ball off a tall building. It very accurately describes the motion of the moon around Earth and through our sky. We use Newton’s laws to figure these things out and how a rocket will fly.

But Newton’s Law of Gravity is wrong to some extent. Einstein’s Relativity corrects that very small error – an error that is only measurable with incredibly accurate instruments and/or when around very massive objects. But that is not our everyday world.

In gravity, Einstein was Newton’s ε. And likely, in the future, someone else will be Einstein’s ε. That’s the nature of science. It progresses as we learn more and more about the universe around us and of which we are a part.

That brings me back to Mrs. Streiber’s remark, which by now you have hopefully figured out why I took issue with it. Yes, Quantum Mechanics provides a more accurate model of the world. And if you wanted to and had supercomputers many orders of magnitude more powerful than today’s best, you could describe a common every-day object as an ensemble of wave equations (seeing as it takes weeks to figure out how to derive even helium – an atom with two protons – in QM class in college, this is not a trivial problem!).

But, if you do that, you will find that beyond all meaningful measurements, classical physics comes up with the same answer. Yes, quantum mechanics is necessary to describe some things in physics, such as the energy spectrum produced by stars, or the photoelectric effect. But it is not used to figure out how to drive a car from home to work, why a volcano erupts, or why a pen can lay ink down on paper.

Final Thoughts

No, Mrs. Streiber, Newtonian mechanics is still relevant and for most practical purposes it is the way the world works. The ε in Newtonian physics is not as large as you think.

ESP/Psi Effects Are Faster than the Speed of Light?


Introduction

First, this is going to be a short post – more of a musing. Many times when listening to or reading material put out by the “alternative researchers,” I will come across the claim of a psi experiment that seems to defy the universal speed limits of light. Could this be possible?

Speed Limits

Anyone older than 5 years living in a place with roads is familiar with the concept of a “speed limit.” You’re not supposed to go faster than it. If you do and you are caught by law enforcement, you can be fined or incur more severe consequences. But it’s more of a, “You’re not supposed to go faster than this” rather than, “It is not physically possible for you to go faster than this.” If it were the latter, then no one would get speeding tickets because their vehicle, by definition, could not exceed the speed limit.

Such is one of the key concepts behind Special Relativity: There is a “cosmic” speed limit where one of the physical laws of the universe are that nothing can exceed the speed of light in a given medium. In “empty” space, this is roughly 300,000,000 meters per second (or 186,000 miles per second as it is more commonly expressed for those who don’t use metric). The purpose of this post is not to get into the finer points nor evidences for Special Relativity, so suffice to say for the moment that it is a theory in the scientific sense — it has withstood every experimental test.

The one possible exception is the idea of “quantum entanglement,” where if two particles (as in not people, people are not made of one single atom or sub-atomic particle) are entangled, and one’s state is changed, the other will change instantaneously, faster than Special Relativity would seem to allow. This is part of the reason why relativity breaks down at quantum scales, while quantum mechanics breaks down at relativistic scales, and why unifying the two is one of the great goals of physics today.

Anyway …

Size of Earth

Earth is about 6378 km in radius. Its circumference around the equator is 40,075 km (24,902 miles). My point here is that 40,075 km < 300,000,000 m (24,902 miles < 186,000 miles).

In fact, light can go around the entire planet about 7.5 times in a single second. This is one of the few things I actually remember from watching a video in 3rd grade.

Claims

The psi claim will often go along the lines of this example I just heard on an old 2006 Coast to Coast AM episode: “A mother and child are separated by a vast distance, about 100 km apart, and the child is induced with pain by pricking them with a pin repeatedly. Amazingly, the mother, who is hooked up to an EEG, shows a response to the child’s pain faster than the speed of light would allow!!”

Let’s see … 100 km apart, and light travels at 300,000 km per second. So it took light 0.33 milliseconds (0.00033 seconds) to go from the child to the mother — and that’s assuming that we’re talking about some form of light that can travel through buildings. And let’s actually assume that we are talking about something that really could break this speed limit imposed by Special Relativity.

In order for this claim to be true, the following conditions must have been met:

  1. The person or machine pricking the child must be timed to sub-millisecond accuracy, preferably microseconds, but at least on the order of 100 microseconds.
  2. The mother’s EEG must also have resolution on the order of 100 microseconds. Based on this article, the best EEGs have resolutions 10x worse.
  3. The clocks at the two locations must also be synced and have resolutions better than on the order of 100 microseconds.

What’s the likelihood of all these conditions being met? And then, what is the likelihood that there was not an experimental error, as opposed to overturning other very precise timing experiments that have been done that verify Special Relativity?

Final Thoughts

When listening to shows and reading articles where people talk about ESP/psi research, this claim crops of fairly frequently without any real justification nor details into how the experiment was done and the actual controls on the timing. People do not seem to have a concept for how quickly light really travels, for they seem to ignore that these experiments would require the effect to be timed down to the microsecond across significant Earth distances. If you’re talking about a similar experiment done in the same building (say, 100 m instead of 100 km), then you would need timing resolutions down to the nanosecond.

When you hear these claims, they may sound interesting, but be skeptical and search further to see if – for lack of a better way of putting it – the person knows what they’re talking about. And in many cases, find out if the alleged experiment even took place.

Please, Don’t Appeal to Quantum Mechanics to Propagate Your Pseudoscience


Introduction

There is no formal logical fallacy that I know of called “Appeal to Quantum Mechanics,” but I think it should be on the books. It is a frequently utilized term by purveyors of New Age beliefs and other ideas to try to make their ideas seem more sciencey when, in fact, to anyone who actually knows quantum mechanics and slaved away for tens of hours a week on QM homework, it just makes them sound stupid.

This post is another about Andrew D. Basiago, in particular his interview on the Coast to Coast AM radio show from November 11, 2010. In it, he discussed his supposed involvement in “Project Pegasus,” alleged the early time travel work done by the U.S. government. For those of you who have a very good memory, you may recall I have discussed Andrew Basiago before in the context of his pareidolia-fueled claims of discovering alien life on Mars and demanding that National Geographic publish what he found after blowing up images 5000%, stretching them, and then wildly extrapolating.

Statements by Andrew Basiago

The following are direct quotes from Basiago, mostly from hour 3 of the broadcast:

“In fact, I spent four ‘phantom summers’ in New Mexico … . There was an extensive cover-up of our summers in New Mexico, uh, in this sort of quantum displacement sort of way.”

“I was involved in actual wormholing where I was moving through the quantum tunnel.”

“So the very act of sending the same child or different child to the same ‘event’ was – I guess as a result of the Heisenberg Uncertainty Principle – changing that event a little bit.”

“Actually, what happens is when you go back and visit yourself in the past, you’re somebody from the future visiting your alpha-timeline, then if you interfere with your past at that moment, um, basically Schrödinger’s cat takes over and a new timeline branches off that’s affected by your visit, but then you return to the future that you left.”

George Noory: “Did anything go wrong with Project Pegasus? Anything?”
Basiago: “… Certainly the notion that propagating holographs of past and future events somehow destabilizes the quantum hologram, that was suggested by the Dan Burisch testimony, provided to Project Camelot, is not true.”

What Is Quantum Mechanics?

Without going through math and a lot of explanation that is not the focus of this blog post, quantum mechanics is basically the physics of the very small. We’re talking about what happens on atomic scales, what happens with electrons (sub-atomic particles), and light. We are not talking about time, space-time, nor any object on the macro-scopic scale, where “macroscopic” means in this context objects that are about the size of a cell or larger (collections of millions of atoms).

Quantum mechanics is weird. In fact, it almost fits the very definition of “weird” since many of the observations at atomic scales defies our concept of how objects “should” act. I think this is why a lot of purveyors of modern pseudoscience rely on an appeal to quantum mechanics to describe how their ideas work: Since most people don’t understand quantum mechanics beyond the “things get weird” part, people are more willing to accept a “quantum mechanics says this can happen” claim and just trust it.

But quantum mechanics is not magic. You cannot use quantum mechanics to argue that psychic powers work. Or that time travel is possible. Or even that information (which also has a very specific definition) can be transmitted instantaneously.

Quantum mechanics has a very specific set of rules and governing equations that have been verified to be correct to within measurement capabilities. (Hence it is also a “theory” in the scientific sense.)

Because quantum mechanics does not make sense to many people in our every-day world, physicists have come up with some analogies that are used to describe some of the consequences of the field. For example …

Schrödinger’s Cat: One of the consequences of quantum mechanics is that a particle‘s state will not be known until it is observed. I remind you that in this field, “particle” and “observed” have very specific definitions and cannot be extrapolated to, for example, “person calling the telephone” and “picking up the phone” (yes, people do make that extrapolation). In fact, the consequences of this had three different interpretations in the early days of the field, where the Copenhägen interpretation was that the particle actually exists in all states until it is observed. This turns out to be the actual way it works (experimentally determined a few decades ago), but in the early days there were two competing ideas, one being that it exists in a particular state, we just don’t know what it is until it is measured. This is where the famous Einstein quote comes from: “God doesn’t play dice with the universe.”

In order to think of this from a more familiar scenario rather than an electron’s energy level, the idea of Schrödinger’s cat is used, where Schrödinger is effectively the founder of quantum mechanics: A cat is placed in a sealed box from which no information can escape. A piece of radioactive material is placed in there before it’s sealed, where the release of the poison is a purely random process (governed by quantum mechanics). After the box is sealed, an outsider cannot know whether the cat is alive or dead because they do not know if the poison has killed the cat. Therefore, for mathematical purposes, the cat is described as both alive and dead. It is only after the box is opened and you make the observation that you know which is the case.

Definition of “Quantum:” In physics, quantum does not mean “magic” nor “[fill in the blank with something].” It has a very specific definition: A discrete quantity, usually of energy. In fact, the whole field of quantum mechanics is based around the idea that energy cannot come in a pure spectrum of intervals, but it can only happen in discrete – albeit very small – packets. This was a very novel idea 100 years ago and it still surprises many people. But, that’s what “quantum” means, no more, and no less. Putting it in front of another word does not make that other word suddenly mean something different. In fact, as it is normally applied, it makes the other word meaningless.

Heisenberg Uncertainty Principle: Again, this has a very specific definition – and a mathematical one at that: Δx·Δpħ/2. What this means in words is that the change in position times the change in momentum must be greater than or equal to half of h-bar, where h-bar is h/(2·π), where h is Planck’s constant (a very small number). Unless you’re a physicist or have really studied the field, you are probably thinking some combination of, “huh?” and/or “what the heck does that mean?” In plainer English, the consequence of this is that when we measure a particle’s position or momentum, the more precise we measure that value, the less precisely we can know the other. This is not because of our measuring equipment, rather it seems to be a general rule of the universe, that the particle’s other quantity really, literally, becomes less defined and knowable.

Let’s Apply This to That

Now that you have taken a crash course in quantum mechanics, let’s take another look at some of Basiago’s comments:

Basiago: “In fact, I spent four ‘phantom summers’ in New Mexico … . There was an extensive cover-up of our summers in New Mexico, uh, in this sort of quantum displacement sort of way.”
Analysis: Sticking “quantum” in front of “displacement” makes it next to meaningless. If anything, a “quantum displacement” would mean that he has physically moved less than the width of an atom.

Basiago: “I was involved in actual wormholing where I was moving through the quantum tunnel.”
Analysis: Again, sticking “quantum” this time in front of “tunnel” still makes this a meaningless phrase. “Quantum” does not have anything to do with, effectively, the fabric of the universe, and wormholes are more of an application of General Relativity, something very different from quantum mechanics.

Basiago: “So the very act of sending the same child or different child to the same ‘event’ was – I guess as a result of the Heisenberg Uncertainty Principle – changing that event a little bit.”
Analysis: Now that you know what the Heisenberg Uncertainty Principle is – you cannot know both the position and momentum of a particle to arbitrarily high precision – you can see that the idea of time travel paradoxes has nothing to do with it. This is an appeal to a scientific term and equation that has zero bearing on the claim, showing (a) his lack of understanding of quantum mechanics, and (b) fairly good evidence (if you didn’t have it already) that his claims are made up.

Basiago: “Actually, what happens is when you go back and visit yourself in the past, you’re somebody from the future visiting your alpha-timeline, then if you interfere with your past at that moment, um, basically Schrödinger’s cat takes over and a new timeline branches off that’s affected by your visit, but then you return to the future that you left.”
Analysis: This is very much like the above example where Basiago made a conjecture from his story and then inserted a thought exercise from quantum mechanics to try to make it sound more believable, when in actuality the insertion shows again he has no idea what he’s talking about.

Noory: “Did anything go wrong with Project Pegasus? Anything?”
Basiago: “… Certainly the notion that propagating holographs of past and future events somehow destabilizes the quantum hologram, that was suggested by the Dan Burisch testimony, provided to Project Camelot, is not true.”
Analysis: This is another example of the first two where Basiago has inserted the word “quantum” into his sentence in the apparent hope to make it sound more sciencey and hence believable when, again, it makes the phrase even more meaningless than it would be without it.

Final Thoughts

Please, whenever anyone uses any form of appeal to quantum mechanics to explain their fringe claim, do a little bit of research to figure out what the term actually means and whether it applies to that situation. I have tried in this post to point out the three most commonly used quantum mechanics terms that have been borrowed by today’s pseudoscience in the hope that you are now armed with some of the information necessary to critically analyze various claims.

And for those of you who are prone to make these kinds of claims, a few words of advice: Stop using quantum mechanics. It does not mean, “Anything you can dream up, I can do.”
