Eat shit Albo, fucking biggest disappointment ever. So much potential from the supposedly left faction of Labor and we still cop shit like this.

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…

Other than messing around with the beta for half an hour, I thankfully never had to use it.

Unpopular opinion that I have no justification for: I don’t mind windows 11 all that much

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.

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?

Oh god the case for a photon is super hard to talk about in any meaningful way, photons “see” every point in their journey as happening at the same instant of time and at the same place, null geodesics are nuts.

But yeah, the underlying mathematics that causes this can (kinda) just be pinned on the normalisation of the four velocity, which I think is what you’re describing.

Only a few really dry textbooks I’m afraid, it’s a subject that’s extremely difficult to explain in lay terms as the mathematics is so complicated.

That said if you’re feeling masochistic, Schultz’s first course in GR is the most approachable that I know.

It’s just meant as a physical analogue to demonstrate some features (namely how the shape of the sheet/gravity affects things that travel on/through it) in a way that people can understand easily.

Variational principle goes brrrrr

Oh yes let’s talk about my favourite subject ever!

The coolest thing I know of comes from wondering why bent spacetime makes you move at all. The answer is that you always move through time and the bending of spacetime actually turns a bit of time into space and vice versa.

This leads to my favourite saying about black holes, once you enter them you can no more escape falling to the singularity than you can escape tomorrow.

Holy shit this is some of the absolute worst data visualisation I’ve ever seen, thankyou for this

There’s basically no way to answer these questions using real physics I’m afraid.

It definitely can’t close it’s mouth faster than the speed of light. Yes it would have a strong gravitational pull, almost definitely so strong that it would just collapse into a black hole and not be able to exist. If it weren’t that dense, then it would basically just be a big diffuse gas cloud that couldn’t do much anyway, it would basically have to be a proto galaxy to not collapse into one.

If it’s using magic to exist, then anything is on the table.

That’s not entirely accurate, the force it applies to close it’s mouth would probably travel at or close to the speed of sound along its jaw, but it could reach the speed of light by applying that force if you ignore a number of problems. One of which is that it will turn into a black hole at that scale, it’s much too dense.

On your second point, it’s hard to make any of those into galaxy killers. Supermassive black holes exist at the centre of virtually every galaxy and don’t do a ton, and even quasars only have limited killing range as there are limits to how collimated a beam of radiation can be. White holes are more complicated and I don’t have enough space in a single comment to go into the nuances, but they’re about as harmless as black holes really.

The only thing I can think of that would destroy all life in a galaxy would also destroy the universe, and that’s to trigger a false vacuum decay, but that might not be possible anyway.

All my homies hate trans-medicalism, this will inevitably lead to a “cure” or something bullshit like that, we don’t need medical validation in the first place

Yeah, I was going to say, we have gulags here…

I appreciate you saying this! I didn’t want to type up anything specific myself because it was pretty late and I didn’t have the energy to check any claims.
