I was just reading a discussion on Instagram (a mistake) which said that if gravity was a bit stronger the universe would collapse (yes) or a bit weaker it would expand and fly apart forever (again yes). It then goes on to say, since gravity is so precise God MUST exist! I took umbridge at this I said :

Huh? There were possibly other universes that collapsed or expanded.. We are just lucky to be in this one. Its not precision its just that we are able to observe it. Its like saying I’m five foot three tall, therefore my short trousers fit!

In any case the Universe IS expanding, There is a considerable red shift and we can see Galaxies are moving apart. There is no sign that its slowing down… Has God forgotten and left the Universe on too low a gravity? I know – I’m cynical.
