There is no “center of the universe” as far as we’re aware I’m pretty confident. We (each individual) is the center of their known/knowable universe, but that’s distinct from the actual universe. There’s stuff beyond that that we can and will never observe.
I guess you could define the center of the universe as the average point of all matter, but since we can’t observe much of the universe we can’t know where that is.
Relative to what?
The center of the universe, I suppose. How fast is the Milky Way moving away from the center? I imagine quite fast.

There is no center, and there’s no fixed grid. It’s still funny to think of the atmosphere stopping from the sun’s reference frame, though.
