EXCERPT (Sabine Hossenfelder): . . . And that’s the problem with the black hole information loss paradox. The temperature of the black holes that we can observe today is way too small to measure the Hawking radiation. Remember that the larger the black hole, the smaller its temperature. The temperature of astrophysical black holes is below the temperature of the CMB. And even if that wasn’t the case, what do you want to do? Sit around 100 billion years to catch all the radiation and see if you can figure out what fell into the black hole? It’s not going to happen.
What’s going to happen with this new solution? Most likely, someone’s going to find a problem with it, and everyone will continue working on their own solution. Indeed, there’s a good chance that by the time this video appears this has already happened. For me, the real paradox is why they keep doing it. I guess they do it because they have been told so often this is a big problem that they believe if they solve it they’ll be considered geniuses. But of course their colleagues will never agree that they solved the problem to begin with. So by all chances, half a year from now you’ll see another headline claiming that the problem has been solved.
And that’s why I stopped working on the black hole information loss paradox. Not because it’s unsolvable. But because you can’t solve this problem with mathematics alone, and experiments are not possible, not now and probably not in the next 10000 years.
Why am I telling you this? I am not talking about this because I want to change the mind of my colleagues in physics. They have grown up thinking this is an important research question and I don’t think they’ll change their mind. But I want you to know that you can safely ignore headlines about black hole information loss. You’re not missing anything if you don’t read those articles. Because no one can tell which solution is correct in the sense that it actually describes nature, and physicists will not agree on one anyway. Because if they did, they’d have to stop writing papers about it... (MORE - missing details)
