Black holes truly are one of a kind. Before I answer What’s inside a black hole, I first had to figure out what exactly is a black hole. 

Basically, a black hole is a region of spacetime where gravity is so strong that nothing can escape. Padi Boyd says the name “black” comes from the fact that not even light can escape. The gravitational and attractive forces are so strong they don’t suck things in; rather, they pull things. Even though there are no light sources, black holes are not empty. They have a mass concentrated into one place. This point is known as a singularity. Ragina Caputo says “We can’t make anything like a black hole on earth to study it. And so, if we really want to understand how gravity interacts with all the other forces in the universe, it’s really a playground for understanding how gravity works, how fundamental particles work, how stars collapse in on themselves. “As a theoretical matter, if you survived entering a black hole, part of you would cross over into the event horizon and most likely the rest of you would follow shortly afterward. In an instant, you’ll find yourself inside a black hole, never to be seen again. Almost. That’s where it gets crazy. You might experience this if a friend were watching you, but while it happens slowly, you may appear frozen in time as if you have never passed through the event horizon.  This is because the gravitational forces stretch out time.  Really, it bends the reality of our universe. In reverse, the opposite occurs from your perspective. Therefore, if you watched someone, they would seem to be moving at warp speed.  Once inside that’s your universe.  Again, scientists don’t know what you’d see or feel they can only theorize. But at some point, you would become one with the singularity. Basically, they think you’d be compressed into a tiny speck.
