Is there a spot where the big bang happened? do we know where it is? Is it the center of the universe? If you go there, is there a net force of zero acting on you in all directions ( gravity)

EDIT: Wow thanks for all of the answers and the support, this is my most popular post yet and first time on trending page of this sub! (i’m new to reddit)

The big bang happened *everywhere*, right where you're sitting now included. The universe doesn't have a center; instead, *everywhere* is equally the center. When we talk about the universe expanding, what we mean is that *space itself* is expanding, not that the universe is expanding into something or away from a center point.

This is a difficult point to grasp, but it helps if you remember that the universe may well be infinite - it's only the *observable* universe that's finite, and that's because of two things: 1) light takes time to travel and 2) the universe hasn't always existed. There's more universe further out, ad infinitum, but the light from those parts hasn't had time to reach us yet. The stuff inside the universe is being carried away from the other stuff inside the universe as space itself expands, like a baking cake carrying raisins inside further away from other raisins as it rises.
