That is an interesting question. One I don’t think I’ve heard before. Since all the matter and energy of our universe would have been in such a small volume, density would be extremely high and would curve spacetime severely. This would have the effect of dilating time relative to us so a minute of that reference frame would be considerably longer than one of our minutes. I’m not certain that’s right, I’m not considering inflation and that will take some more thought. It’s difficult to quantify but that “feels” right to me. Thanks for that question, you’ve given me something to ponder!
