Our Universe has no Center

From our vantage point, the Universe is expanding and cooling, with all but a few of the closest galaxies receding from our view. In fact, the farther away an object is, the faster it appears to recede. 

This may sound an awful lot like what occurs in an explosion to you, especially if it were centered on us. Furthermore, the name “the Big Bang” sure gives that same implication, doesn’t it? Yet despite these facts, it turns out that the idea that the Universe has a center is completely false, and is actually contradicted by both relativity and the Universe that we observe. Source
