Same with absolute zero. Our “laws” of thermodynamics apply less and less the closer we get to reducing something to absolute zero.
Well, I would be wary of using that as an analogy because the laws of thermodynamics do actually apply in well-defined ways right up to the point of zero. The issue is with the point of zero – particularly in the case of the Big Bang. What you have is a singularity: a point of infinite density. All the stuff in the universe is crammed into one infinitely small point. When you get zeroes and infinities involved mathematics ceases being able to do anything meaningful, and that’s why the laws of physics break down (the laws of physics are mathematical…).
