Back in the 1980s Quantum Gravity looked like a holy grail, post-2000 it has become a highly competitive field with many theories and the problem is not that we need a conceptual breakthrough but rather we can't tell these theories apart experimentally.
I feel like a dolt for ever believing the classical theory of a black hole interior, I'm pretty sure a real black hole looks pretty different. I guess I could go in and take a look but the problem is I could not get out to tell y'all what I saw!
I believe there is no interior of a black hole - because black holes never form. From the perspective of an object falling into a black hole, it hits an impenetrable wall of Hawking radiation and is forced out. From the perspective of a distant observer witnessing this, the object appears to "fall" pass the Schwarzschild radius because it's so red-shifted we simply can't see it. Then trillions of years later it's bounced out. Extreme time dilation causes extreme observations. As a bonus, we avoid this whole singularity business.
