Underselling Hawking
- PaulHoule 5y agoI think the "black hole information paradox" held back progress in quantum gravity for 30 years. Given that it is so hard for young physicists to get established it really is a crime that somebody established was able to sustain such a thought-stopping bad idea for so long. That is, if quantum theory is true, there is no information loss in a black hole... Or rather any quantum theory of gravity is not going to give you that result so if you're hung up on that idea you are not working on quantum gravity. Other than insisting on that, there is no fundamental difficulty with quantum gravity in theory... but a lack of experiments is a real problem.
