If gravity is a particle... How come it can escape a black hole? ๐ค

A "Showerthought" is a simple term used to describe the thoughts that pop into your head while you're doing everyday things like taking a shower, driving, or just daydreaming. A showerthought should offer a unique perspective on an ordinary part of life.
Maybe gravitons aren't affected by gravity, the same way photons aren't affected by em interactions (which they carry).
If that was the case, we would already have a quantum theory of gravity. The fact that "gravitons" (here I mean the particles of a second quantisation of GR) can interact with themselves makes the theory almost completely useless.
It's technically possible to write down such a theory, but the only way to get results out of it is to first perform an infinite number of experiments.
