What Is Inside a Black Hole?

We don't quite know what's inside the event horizon. There could be a bunch of strings, there could be photons inside af black hole. The event resint actually may not mean anything. You may go through and event, the event resinanc inside, you find empty space. It's quite possible. Until we find a proper working theory of quontum gravity, a quantized theory of gravity, we will not quite know. And that's the search that everyone is making, the search for quantum gravity,. That's what everyone's looking for.
