Reply to comment by tea_and_biology in Why didn't heavier atoms originate in the Big Bang? by omigodd

Thanks. I got an irrelevant question after reading your answer though. How can you say something after big bang took X minutes if the time bends with gravity and such. Wasn’t the whole universe there after 3 minutes of big bang?

Gravity measurably affects the passage of time for observers at different gravitational potentials. So a clock at the centre of the Earth would run slower than one on the surface. But the early Universe was almost perfectly uniform, so while it was extremely dense, the gravitational potential was equally close to being uniform and so there was no time dilation.
