Astounding Evidence that Creationism Is a “Science Stopper” – Click Here to Find Out How, with Pluto and Friends!

Okay, so I’m not great at the click-bait headlines.

I was glancing through some of the young-Earth Creationist mainstream sites, as I do with some regularity, and I came across the Institute for Creation Research’s “Looking Back at Pluto” by Jason Lisle. Being involved with New Horizons (though this blog is completely separate from that work/employment), and given that Dr. Lisle graduated from the same school and program I did (but a summer before I got there), I had to click.

Jason goes through some of the interesting things we found at Pluto. In particular, he highlights: (1) The craterless (as far as we can tell) Sputnik Planum area (which he mistakes for Tombaugh Regio), (2) the polygonal terrain in Sputnik Planum that is likely due to convection, (3) giant ice mountains and cliffs and canyons, (4) potential cryovolcanoes, (5) dark red area at Charon’s north pole, and (6) some of its small satellites spin really fast.

For Realz scientists are studying these features, developing hypotheses to explain them, and testing those in the lab and/or with the data returned by New Horizons. And some of them just aren’t mysteries at all because Jason hasn’t done his homework.

For example, for point (1), going in we expected that Pluto may be devoid of many craters because its surface is constantly sublimating (turning from ice to gas) as material gets transported around the body from the summer pole to the winter pole. (Pluto, like Uranus, is tilted on its side so right now the north pole is in constant sunlight.) Jason also said that having the encounter hemisphere be the bright “heart” was “by providence,” but it was specifically planned years in advance based on the (now primitive) maps we had from the Hubble Space Telescope — that area displayed the largest ranges of brightness, so it was the area we wanted to see up-close the most. It’s not providence, it was planning exactly the way you would when doing Real Science.

Another example is point (6), where yes, we would expect satellites to not rotate really fast because tidal effects should slow down the spin rates over long periods of time. If I can replace gravity for magnetism for a moment, imagine holding a strong magnet in place, and several inches away have a bar magnet that is on a post that it can spin freely around but it can’t get closer to or farther from the magnet you’re holding. Spin the bar magnet. It’s going to slow its spin pretty quickly to align with the one you’re holding. That’s kinda sorta how moons tidally lock and slow their spin except the force is gravity rather than magnets.

Anyway, at least one of the moons spins on its axis, fully, in about half a day. Is it young? Maybe possibly but unlikely … but that particular moon also has giant craters on it, so it’s just – if not more – likely that it recently (as in within the last few million years) got whacked by a large piece of debris that simply spun it up, increasing its rotation rate.

I can’t discuss papers that have been submitted by other authors on the team, but there are very plausible, natural explanations for several of the other features Jason lists, that are currently undergoing peer review, with conclusions based upon the available evidence.

As for the attempt at click-bait title? Here’s how Jason ends his article:

These are perplexing problems for secular formation scenarios. However, Christians delight in seeing the Lord’s creativity continually revealed.

In other words, his brand of Christians just STOP at the observation, attribute it to their god, and move on. How is that not a science stopper?

  1. And of course it’s all worse that Dr Lisle is an actual astrophysicist and knows in detail what rubbish he’s spouting.

    (Has he done anything in astrophysics in the past few years? Or did he get his degree, publish some papers and go straight to the ICR, never to be seen in astrophysics again?)

    [I was slightly surprised to discover he’s one of these people that RationalWiki has an article on but Wikipedia doesn’t.)
