This little announcement was making the rounds earlier this week – a conference on the Geocentric model:
Geocentrism is the view that Earth is the center of the universe, the immovable point around which everything else (the Sun, the planets, and all the stars) revolves. As you might gather, there aren’t a lot of Geocentrists out there anymore; between Galileo’s observations over 400 years ago on to today, the evidence against Geocentrism has grown. We’ve learned what stars actually are, established that Earth’s place in the universe (while privileged in terms of galactic environment and position with respect to the Sun) isn’t anything special.
Phil Plait has a pretty good takedown of this conference, going into specifics about why we know the Geocentric model doesn’t work, no matter how you interpret it, so I won’t repeat what he says here. Instead, I wanted to pick up on the first talk listed from the conference: “Geocentrism: They Know It But They’re Hiding It”. I presume “they” means all astronomers and scientists, including me, the teachers who trained me, and all my colleagues worldwide.
I’ve always been bemused by conspiracy theories, and now that I’m a professional scientist, I find I’m accused of being part of conspiracies now and then. (Not directly – I’m too unknown for anyone to include me personally.) You’ll have to take my word for it, but I was never indoctrinated into any conspiracy. Nobody taught me the secret handshake, or informed me that my work was an attack on the very roots of Western civilization, so good job, me. I’ll have more to say about this in a later essay, but if I’m not an initiate of the Great Geocentric Coverup, that makes me a fool of the worst type.
Because, you see, I learned in school, college, and my graduate work how to understand and process evidence from a scientific viewpoint. It’s not a mysterious thing – anyone can do it with sufficient patience and curiosity. Instead of asserting a pseudoscientifc position (Geocentrism, in this case) and positioning it as a conflict of opinion (Galileo vs. the Church Fathers, which would make for a very boring comic book), scientists collect and interpret evidence. Evidence doesn’t exist in complete isolation, since it is always interpreted in the light of theory, but that’s not the same thing as saying we just make stuff up.
When Galileo was working, 400 years ago, telescope technology was still new and physics as we know it today was in its infancy; Galileo played a large part in developing both. Perhaps at that time, one could argue that the evidence in favor of the mobile Earth wasn’t that strong, but today? That’s an entirely different matter. If I assert the Earth is moving, it’s not my opinion, or Galileo’s, or Isaac Newton’s, or any one person’s view – any more than evolution is merely Charles Darwin’s idea or relativity is merely Albert Einstein’s dream. All of these things are shaped by multiple scientists, using a variety of methods and finding consistency. Reduction of the process of science to one or two personalities and accusations of conspiracy is an insult to the intelligence not only of scientists, but to any thoughtful person.
