  The earth is like an egg. But you first have to boil the egg for
3 minutes..then remove the earth crust, and cut the egg in half and you
will see the earth's core.
 

The current thinking is that the universe is infinite in spatial extent, but only 13.7 billion years old. In consequence of its finite age, we can only see a finite amount of it.
So whether it's really infinite in extent is not something we actually know, and can probably never know. We also don't know whether the physical laws are really the same everywhere. There could be variations that are too small to be detectable in the amount of the universe that we can see.
In some ways, having physical laws that vary over the universe is philosophically attractive, because it could be an answer to why the laws we see seem so finely tuned to support our existence.
