OH YARN I don't have my glasses and I couldn't work out how someone was knitting with a yam
No idea if I can reply to a deleted comment but I read the root comment totally wrong and just restated everything they said. My bad.
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.
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.
I briefly worked in this area of physics, it's complicated and depends on your definition of a particle and which quantum gravity model you're talking about.
To simplify things you can just ask the same thing about non-quantum gravity. Why does gravity escape the black hole? The painfully mundane answer is that the black hole is gravity, it's not escaping itself. Gravitational waves can't be emitted from inside the black hole but that's because those are a form of radiation and not the structure of spacetime.
This is specifically important because even quantum gravity (the kind with gravitons) still has this distinction. Particles belong to a field and are excitations of it, the gravitational field itself is not made of those particles. The force associated with that field is mediated by gravitons, but what that really means is complicated and honestly possibly just the result of a cool mathematical trick. It also comes with a bunch of crazy behaviour where you have particles that can break the laws of physics by just kinda doing it so quickly that nature blinks and misses it.
The point is, the quantum gravitational field is enough for the black hole to do its job when objects come by, gravitons don't actually need to escape, though they are involved in complicated ways.
Ah right fair enough, I'm just talking about the situation in Australia
The safety isn't about lane filtering so much as just intersections, but yeah it's a rubbish argument and any biker making it should shut the fuck up if they don't wear hi-vis on every ride
Hard agree, unsubscribed from real engineering the moment I realised they made ads without ever declaring it. It's literally just propaganda at this point
Bought a mandolin today and I can't put it down, I can't wait to write tons of pretty songs :3
