My question is; if time slowes closer to a black hole then at the beginning of the Big Bang when the universe was infanitnly dense, wouldn't time move infanintly slow? Wouldn't one second last for eons? I have a few other questions related to that, but I will start with this one.
Ahh, well it's not true to say that time slows down close to a black hole. The truth is a bit more subtle. If, let's say, you and a buddy of yours were having a conversation close to a black hole, time would appear completely normal. It's only if one of you was close to the black hole and the other one wasn't that you'd see the time dilation. So even though the universe was very dense at the beginning, time would still seem to pass normally to all things in the universe. This is especially true because, at the very beginning, the universe had pretty much uniform density throughout. Therefore, time passed at nearly the same rate at all points within the universe, and there were no points where time seemed to stand still.
Note: This question was also answered with help from Jim Fuller.
