What the fuck happened to quantum gravity? Why does no one study it anymore?
>>16816511People do study it. Are you a physicist/academic? Do you check out new papers on the arxiv and in journals? Do you go to conferences? How would you know what physicists are studying?

>>16816511This picture makes absolutely no sense
>>16819719It's the page image for quantum gravity.https://en.wikipedia.org/wiki/Quantum_gravity
>>16819749No way this is real.
>>16819719You’ve been filtered. It makes perfect sense.
>>16816511It’s very different from the other forces in that it is spin 2. This makes it>unique (in the sense that every massless spin 2 field must obey EFEs)>extremely non-linear>the group that governs the dynamics is an infinite-dimensional Lie-Frechet group, the diffeomorphism group of 3+1 dimensions, which is far worse behaved than the usual finite-dimensional Lie groups of the other forces>the (3,1) signature makes the dynamics mathematically ill-behaved in many ways, non-compactness being a major one>the gravitational constant is not dimensionless, making vanilla renormalization procedures fail>other forces treat spacetime as the “background arena” whereas gravity is directly tied to spacetime >the naive Hamiltonian, canonical quantization is very problematic because the Hamiltonian formalism separates time>the naive Lagrangian, covariant quantization is very problematic because of the aforementioned dimensionality and non-compactness issues

>>16816511Cause quantum physics is bullshit.You see pictured?You see how there is a countable number of peaks and troughs visible?That's where "quantization" comes from."Quantum" effects are a natural emergent consequence of oscillation.
