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.

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.
