Do We Have a Worm Hole?

In theory, you can make a worm hole. So the theory is that maybe if you go into a black hole, you actually exit the black hole somewhere else in the universe. And do they definitely exist? Not necessarily. It's not ar they only theorize. There are very huge practical problems to putting it together. The laws of physics don't allow us to through time, and then we can't do anything about it.
