I have watched this conversation regarding the start of the universe for a while now, I first got interested when you made it clear that you implied that the farthest observable galaxies were 13.3 billion light years away. And you implied that the universe can not expand faster than light. Both wrong and it shows your complete misunderstanding of the universe.<quoted text>
"It is difficult enough to imagine a time, roughly 13.7 billion years ago, when the entire universe existed as a singularity. According to the big bang theory, one of the main contenders vying to explain how the universe came to be, all the matter in the cosmos -- all of space itself -- existed in a form smaller than a subatomic particle."
That gravity! The gravity of the entire universe.
Now regarding gravity, I (nor anyone else) is here to educate you, that is up to you (if you think it worthwhile) but I will tell you that it did not work that way. Matter did not exist therefore no gravity.
