I don't see any good evidence for or against this. It's not like we can point a telescope in some direction and see the Earth really faint in the distance.
Yet.
Figure out how to test this and earn yourself a Nobel Prize.

Not the center of the universe. The whole universe.
The story goes that the universe has stopped expanding and then contracts again. It's not moving back through itself; it's contracting.
When the Big Crunch happens, it will happen everywhere, all at once. Just like the Big Bang. It didn't happen at the "center" so much as it WAS the universe. The entire universe was the entire Big Bang.
The Big Bang isn't something that happened to the universe any more than being a toddler is something that happened to you.
(Bear with me on this one, despite it's flaws, I think you'll like it
Where did your toddler take place? Was it in your head? Your belly? No. It was happening everywhere, to all of you. Did you expand into something else as you got bigger? No, you expanded to a bigger you.
(Obv. this is a very loose metaphor, please don't take it any further than this.)
