Graduate What topics in Quantum Gravity don't require QFT or string theory?

Click For Summary
The discussion centers on exploring quantum effects related to gravity that do not necessitate full quantization of General Relativity (GR) or quantum field theory (QFT). Examples mentioned include gravitational neutron interference and the Einstein Box thought experiment. Participants clarify that Newtonian gravity and GR are classical theories that inherently overlook quantum effects. There is a suggestion to seek specific references for further exploration of these topics. The thread concludes with a note that it is now closed.

Full quantization of gravity is a big issue, but that's not what I'm asking here.
I'm asking about quantum effects that involve any form of gravitation (Newtonian or GR) but that don't require a full quantization of GR or anything like that. Things like gravitational neutron interference or the Einsten Box thought experiment.

Newtonian gravity and GR are classical theories; by definition they ignore any quantum effects.

You seem to be asking for quantum effects that don't require a quantum treatment. That makes no sense.

If you can find specific references about these things, you can start a new thread asking about those references. This thread is closed.
 
I am slowly going through the book 'What Is a Quantum Field Theory?' by Michel Talagrand. I came across the following quote: One does not" prove” the basic principles of Quantum Mechanics. The ultimate test for a model is the agreement of its predictions with experiments. Although it may seem trite, it does fit in with my modelling view of QM. The more I think about it, the more I believe it could be saying something quite profound. For example, precisely what is the justification of...
