Aren't there a few alternatives such as Quantum Loop Gravity?
- orbifold 8y agoQuantum Loop Gravity is much smaller ~200 people most of them not very famous and it has not produced the same depth of research directions in particular not recently.
- auntienomen 8y agoYeah, loop quantum gravity is pretty badly broken as a theory of gravity. It doesn't have the right classical limit (i.e., general relativity). Doesn't even have thermodynamics compatible with the right classical limit. I'd be extremely hard pressed to name a significant result loop quantum gravity has exported to the rest of physics and mathematics. There's also the asymptotic safety program, which isn't completely implausible, but is kind of stuck in the 'steal underpants' phase.
