- Time dilation at the Big Bang 4 answers
I'm not a physics guy, but this is something I have always wondered about. If a clock flown by an object of high mass runs slower, what is the effect of this in regards to the density of the universe. It seems to me that as the universe expands, it would lose density and therefore clocks would run faster as the universe expands. Is this correct? And if so, could this create the perception of an accelerating expansion in a hypothetical universe of constant expansion. I want to understand the things I believe in, and I believe in the big bang. It seems that if the universe were a singularity at some point that a nearby clock would be running infinitely slow. Would the first few seconds of the big bang be perceived as slow, maybe from a distant view, despite much happening in the first few seconds? (I'm not sure how the human brain perceives time). Forgive my complete lack of understanding. I'm just curious if and how this is accounted for in the models.
