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. The best ones are thoughts that many people can relate to and they find something funny or interesting in regular stuff.
Almost none of this applies in the case of something like loop quantum gravity, which I understand very little of but I don't believe it's possible to discuss it using the language of QFT like I have above.
