How do you explain how the universe is so perfect for life?
This is another question I see a lot. There is this notion that the universe is set perfectly in motion and in no other way could life have formed. Some limit this just to life on earth but the same thoughts apply. Firstly the universe is definitely not perfectly tailored for life. In fact the opposite seems true. Most of the universe is space. And it’s huge. “Space is big. You just won’t believe how vastly, hugely, mind- bogglingly big it is. I mean, you may think it’s a long way down the road to the chemist’s, but that’s just peanuts to space.”Douglas Adams, The Hitchhiker’s Guide to the Galaxy. And there is a lot of nothing in there. Seriously there is of area where nothing can survive. If the universe were made to suit life there would be way more places for us to live. Even in our solar system with it’s 8 planets (sorry Pluto) only one of them has the ability to support human life.
Even looking a just earth there are problems with it being tailored for human life. Three quarters of the planet is covered in water. And then there are places like the poles which have such cold temperatures very little can survive there. Also vasts deserts of nothingness. There a very few places where humans can flourish without bringing in outside resources to sustain them. In fact we wage wars and kill each other for those resources, as they are limited and will eventually run out.
I do grant that there are certainly other places that may harbor life outside our solar system, they are relatively small in number. Yes we are finding more and more possible planets in what seems like everyday however, when you think about the scale of the universe this number is minuscule. In short, no I don’t see a universe being perfect for life. I see a universe where gravity and electromagnetic force control how and where things end up.
Side note: Sorry the late post. Time has gotten away from me this week after the holiday. I hope to get back to regular posts shortly!
