Hello everyone. I'm a first time poster, but a long time lurker. I don't have a degree in physics, but I have always held the discipline and all its branches, near to my heart. A little background on the question. I got into an argument with a friend of mine about faith in religion and faith in science. He argues the following: I brought up gravity and it being a constant across space and time in order for our universe to be in the condition it is today. I think I may have backed myself into a corner. I know there is a way around what he is saying, but I just can't come up with it! Logic has never been one of my strong points Any help?
