  • That’s fair, I just like windows and that’s really all there is to it. I’ve had a few Linux installs in the past, but never really found an advantage to anything except compiling this one specific python library, but these days I can do that very easily running WSL, VS code SSH’d to my server or more recently a jupyter server that I can connect to from any device with a web browser.

    Now macOS on the other hand, I absolutely despise. It was one of the first OS’s I learnt to use back in primary school, and now that I have to use it for work I have absolutely no nice things to say. Unintuitive, missing basic features and slow to navigate, and I can assure you that none of this is due to unfamiliarity…







  • 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.
