Big Bang: Spacetime Created in 1 Sec

[TerryHM]

During the first second of the Big Bang a mind boggling amount happened. So much so that we need to measure it in plank time to appreciate all the stages that occur. And in that 'bang' spacetime was created.

My question is this. As space dilated would time not dilate? Meaning. If I were able to be inside the Big Bang as it happens, in that first second, time would speed up as the universe expanded.

Would this not result in me observing that first second as millennia?

Time in our universe and cosmological models is measured by looking at the clocks of co-moving observers in whose frames the universe is homogeneous and isotropic. If you were a different observer, you could have a longer (or shorter) time passing in your clock.
