Does string theory touted as TOE offer a possible explanation of what happens beyond the event horizon?
If not what may?

I agree that this is a key paper. It seems to "make it official" that the classical BH singularity can be replaced with a quantum gravity model of what goes on at the pit of a black hole. And the process of constructing the new picture is far from over.hossi said:I would like to add the ref

which is a very useful discussion about the singularity inside the horizon and the evolution of the spactime. It seems to me that even though the inside of the black hole is hidden by the horizon, the evaporation should eventually reveal what is going on inside - if we understand its process fully. It seems plausible to me that string theory should at least describe part of this - even if it is not the TOE.
Black holes are regions in space where the gravitational pull is so strong that nothing, including light, can escape from it. They are formed when a massive star dies and collapses under its own gravity.
We study black holes through various methods such as observing their effects on surrounding matter, detecting their gravitational waves, and using mathematical models and simulations.
The event horizon is the point of no return for anything that enters a black hole. Once something crosses the event horizon, it is pulled into the black hole and cannot escape.
String theory is a theoretical framework that attempts to reconcile the laws of gravity and quantum mechanics. It suggests that the fundamental building blocks of the universe are tiny strings rather than point-like particles. String theory can help us understand the behavior of black holes and their interactions with other objects.
It is currently impossible for humans to physically explore beyond the event horizon of a black hole. The intense gravitational pull would tear apart any known material. However, we can continue to explore and learn about black holes through advanced technology and theoretical models.
