Gravity Can Be Neither Classical nor Quantized by Sabine ...

I argue that it is possible for a theory to be neither quantized nor classical. We should therefore give up the assumption that the fundamental theory which ...

The proof is in the pudding (Chapter 8) - Discrete or Continuous?

(PDF) A possibility to solve the problems with quantizing gravity

PDF | It is generally believed that quantum gravity is necessary to resolve the known tensions between general relativity and the quantum field theories.

James Webb Space Telescope finds evidence for alternate theory of ...

My hangup with MOND is still general relativity. We know for a fact that gravity is _not_ Newtonian, that the inverse square law does not hold.

Why Can't Quantum Mechanics Explain Gravity? (Op-Ed) - Yahoo

Quantizing gravity — and for the faint of heart, don't worry, we'll define what that means soon enough — can't be that hard, could it? I mean, ...

Quantum field theory - Wikipedia

In theoretical physics, quantum field theory (QFT) is a theoretical framework that combines classical field theory, special relativity, and quantum ...

Might There Be No Quantum Gravity After All? - Physics Magazine

There are two strategies for this unification: either quantize gravity or find a way to insert quantum matter into a classical gravitational ...

GUP deformed background dynamics of phantom field

Quantum gravity has been baffling the theoretical physicist for decades now, both for its mathematical obscurity and phenomenological ...

Mathematical explanation of the failure to quantize gravity naively

If it is omitted, we have no way of guaranteeing the correct classical limit of the resulting quantum theory. On the other hand, a Lorentzian ...
