Thanks for this, that’s a fantastic way to phrase it.

Best video you’ll ever see on the topic imo (and very short)
The huge caveat here is assuming gravity is quantised in the same way as the other forces, gravitons don’t need to exist for gravity to exist. This is just the beauty argument of string theory with a new name, it’s cool and I love this type of stuff because it’s amazingly satisfying, but that’s not enough to make it reality.
Don’t get me wrong, this is still useful work but I kinda hate the way quanta reports on a lot of physics…
Corporations have absolutely no incentive to change, consumers need to vote with their wallets if they want something to happen. But no, everytime someone points out this blindingly obvious fact we get the “uhm actually corporations need to change, it’s not my fault they’re feeding off my unsustainable habits.”
We have to work together, we only have power to effect change when we work together, solidarity is our strength.
Why does this kinda look like Doug Walker?
Considering all the failures we see with water distributors just faking tests, I fully expect that this would just lead to someone dumping a bunch of live virus in the water supply lol

It has changed an enormous amount, this article discusses it
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.

If you’re looking for books, then it depends on what field you want to study. Generally just I’d search for recommended textbooks for that field and then I’d definitely buy it and wouldn’t just download it from libgen.is

Now I’m wondering, surely someone has already made a language that’s designed to read like scripture?
I’m basically as old as gen z gets, '97. At home we only had dialup well after broadband was the norm, it wasn’t really worth using. Instead I learnt what the internet is and how it works at school in computer lab classes.
I was probably 7 or 8 when I made my first web page on our school intranet, they really pushed for us to be tech literate. The coolest part about this is that I grew up so tech literate that I was fully qualified for a job as a developer despite having no formal training. I did one introductory programming class in uni for a free HD and that was basically it.
Yeah, I absolutely understand the insanity of having the internet so available. We had it in my early days on school computers, but the real game changer has been smart phones. Being able to carry that information everywhere is the insane part to me.
Parents were strict, but I got around it really easily. I just used the wifi details my dad used for my Xbox to connect my iPod touch. I grew up on YouTube and podcasts from iTunes.
The only thing that keeps me sane while working for capitalists is that I get paid to do a lot of nothing

Just pirate, it’s better than paying these companies to rip off artists. Support your favourite artists directly, streams are basically worthless compared to other forms of income like merch.
