"Yes and no". The universe is not homogeneous on a large scale, there are filaments of galaxies and everything but yes the idea of the center of the universe does not correspond to anything. The Big Bang from current models happened everywhere and the expansions comes from the fact that the very "fabric" of the universe expands.
But there are some awesome implications of an infinite universe, take a look here if you are interested:

- jessriedel 15y agoIn the sense of matter distribution, the universe isn't homogeneous on small scales either. But that's not what is meant in the context of a cosmological model. The global spacetime is modeled with a FLRW metric, whose key property is homogeneity and isotropy.
- lutorm 15y agoOn very large scales, the Universe does seem to be isotropic and homogenous, just like the assumption in the models is.
