I believe gravity can be both quantizable and non quantizable. Gravitons could be like phonons (quantized sound waves) and only exist in the solid state of space time. In the fluid state of space time gravitons don’t exist ( Similar to the fact that phonons can only exist in solids, but not in fluids).
- digging 3y agoWhat are the solid and fluid states of spacetime?
- amai 3y agoOne could imagine that for a very low Unruh temperature spacetime changes the phase and becomes „solid“. A low Unruh temperature means very low acceleration/gravitation. This might explain dark matter. Similar things are discussed in the literature under https://en.wikipedia.org/wiki/Superfluid_vacuum_theory https://en.wikipedia.org/wiki/Superfluid_vacuum_theory and https://penntoday.upenn.edu/news/physicist-theorizes-dark-matter-superfluid https://penntoday.upenn.edu/news/physicist-theorizes-dark-ma...
