So last night kick-started another series of lectures from the Edinburgh Creation Group, hosted at the Greyfriars and Buccleugh Free Church. Take note that I’ve added their blog to my blogroll on the right of your screen. I only discovered it yesterday but it’s good to have a written explanation of a theory. I’ve often said that text such as on websites and forums is a much better medium through which to hold a debate than in person, so maybe it’ll be a catalyst for further blog posts in the future.
Anyway last night’s presentation was entitled “Chosen Planet: Earth’s Uniqueness for Life” by Dr George Marshall. In many ways it was quite similar to another talk last year but it didn’t go anywhere near as far as that one did. Several things were covered that I wasn’t aware of. For example, I knew that the moon caused the tide but I thought it was just the gravitational pull of the moon which pulled the water towards it, causing deeper water. Apparently there is also a high tide on the opposite side of the earth too! The point was that if the moon was closer it would cause catastrophic floods which would hinder the development of life on earth. Any further away, and the oceans wouldn’t be churned up enough to allow nutrients to come to the surface and feed the algae which are so fundamental to the balance of oxygen and carbon dioxide in the atmosphere. But ours is juuust right, so that’s ok (you’ll notice this becomes something of a theme).
Next up is the Earth’s orbit. If it were smaller, we’d be too hot, bigger and we’d be too cold. If our orbit were more elliptical the temperature would be too temperamental, and if other planets had elliptical orbits it would pull ours out of orbit creating the same problem. A bigger orbit would also result in a greater level of vulnerability from comets and asteroids. But ours is just right.
Many stars, including red dwarves, give out massive solar flares which would also make the climate too temperamental to support life. But ours is just right. Our solar system’s location in the galaxy is also idea to support life.
So, as the more astute among you may have noticed, this is no coincidence. We shouldn’t be surprised that, as living beings, we live on a planet that is suitable of supporting life. I was about to point out that the way the world is is exactly as we should expect it if it happened naturally, when someone on the front row came out with “What exactly is your point?” What followed was a very heated discussion whereby the question-asker didn’t at all make himself clear, really annoyed Dr Marshall (who didn’t understand the point he was making at all), and abiogenesis was brought up which has absolutely nothing to do with the topic at hand (oh, I should mention that halfway through the presentation it emerged that Dr Marshall is a biologist, not an astronomer), and the discussion went nowhere. I kind of brought it back up again in a more polite and clear way, and got the answer we were looking for. Dr Marshall wasn’t arguing that all these parameters amount to such a coincidence that God must have done it, it’s just that you have to step back and say “wow”. He still referred to it as a coincidence though, so I don’t think he grasped the idea that it’s not a coincidence at all.
Anyway, I think this shows the importance of at least appearing to be tolerant of people’s ideas. You don’t get anywhere by shouting and screaming, you just kind of come across as a bit childish. We were both on the same page, he just went about it a different way which I think was detrimental to the discussion.
In short, I’d heard all the arguments before and more along the same vein (which if people would like to bring up here I’m happy to discuss – last time Dr Ross’ 101 quantities was mentioned), so it was nothing new, although some things were mentioned that I hadn’t been aware of. It was also claimed that it takes faith to believe in a multiverse or an oscillating universe just as it does to believe in God. I have my own opinion on that and if anyone wants to discuss it further, drop me a comment here.
