What a black hole is and what it is made of.
The center of a black hole is just concentrated matter getting infinitely condensed by the accumulated gravity of the matter. A black hole also swallows the negatively charged particles but leaves positively charged particles floating around it. But the negatively charged particles eat way at a black so slowly the universe is not old enough for that to have happened yet. This also tells us how the universe come to be. The hole universe was originally condense to the size of an atom. Only it was not perfectly round. That’s why the universe is not a ball like shape of Galaxy’s spreading out. So no, black holes don’t take you to another dimension but they do distort this dimension so bad we thought they opened a dimensional rift.
