B The Early Universe and the Laws of Physics

Tags:

    I've heard it said multiple times on here and elsewhere that as we "wind back the clock" of our Universe and the Big Bang that our laws of physics kind of begin to fall apart, in a sense. If this is true, can anyone explain exactly which laws become more difficult to work with, and why? Thanks.

    No, they don't fall apart at all, but they change characteristics. It is believed that at the time when the Big Bang theory starts winding forward, there was only one force, and it early on separated out into the 4 forces we know now.
