Something cannot be inside itself, for if that was the case, what would be surrounding it? For your question to make sense, it would require two universes, but that is by definition impossible because the universe is defined as everything that exists.
the universe is isotropic & homogeneous, meaning there is no center. the observable universe has a center, which is the part of the universe we can see. we are at the center of the observable universe.

This model of the universe placed the Earth at the center of the universe
The universe has NO center
The center of the universe is mind.
At present, there is no way to determine where the "center" of the universe is, or even if the concept of "center" makes sense when applied to the universe.
Well, the universe never stops so... the universe does not have a center.
There is no single spot that can be distinguished as the center of the Universe. To put it another way, wherever you are, it seems you are at the "center" of the Universe.
Apparently, anywhere you are, it would seem that you are at the center of the Universe.
Maybe, but the Sun is certainly NOT the center of the Universe.
You can't.
None. There is no known center to the universe.
