Is in the middle of black hole zero gravity? Then, is there another event horizon somewhere inside black hole?

I don’t think anybody really knows what‘s inside a black hole. That’s kind of their defining property.

Well technically it approaches infinite gravity. It's a gravitational asymptote. But like the other commenter said, no way to know what it actually is in reality, as we only have mathematical concepts that may or may not match reality.

Of course we do - everything that fell in but wasn't radiated out ;)
