Yeah, not surprised. An experienced software engineer in the US won’t have to do unskilled labour unless there’s something else massive going on with them.

It’s “just” curvature, both through space and time. The Einstein field equation literally has energy and momentum on one side, and a type of curvature measure on the other.

The trick there is that curved 2D spaces can already be pretty weird, and it gets exponentially crazier in dimensions 3 and 4. This makes it both capable of doing surprisingly a lot, like putting Earth in a fixed, repeating orbit without much local distortion, and difficult to visualise even by analogy. Interestingly, dimensions 5 and higher aren’t any worse, which is actually a pattern that repeats across a lot of geometry.

But yes the gravitational waves take is interesting, it burn my mind trying to imagine how to “trap” spacetime in itself.

There is a bit of nuance there, which is why I said “as I understand it”. Gravitational waves are classically defined in terms of perturbations of flat spacetime, and a black hole is nowhere near close to flat. It’s possible there’s been work showing how to define them in that context, but I’m not a specialist and I couldn’t name it.

If this were electromagnetism I’d just use the superposition principle, but GR is not linear. In fact, there’s chaotic dynamics that can happen in black holes related to the Mixmaster universe model. It’s also possible (to my limited knowledge) that there isn’t nice propagating waves at all so much as just adjustments to the crazy bending everything is already doing.

In this specific case, the gravity of the apple just never went away. It exerts one apple mass before it starts to fall, while it’s falling, and whenever it crosses the event horizon from your point of reference.

Nothing is actually being “transmitted” per general relativity here. If someone were to jump in with some kind of gravitational wave generating device and send you a secret message from inside, that would be a straighter example. As I understand it that would not work; the waves follow null geodesics (light-type trajectories) and would be trapped with everything else. Which is weird, because spacetime is trapping itself, but deep physics is under no obligation to act normal.

I clarify my question: beyond the event horizon of a black hole, according to general relativity, the space-time flows faster than the speed of light. If it is the case, then, no information can be transmitted from here.

It’s a bit of a nitpick, but I’m not sure I’d use “flow” here. That makes it sound like it’s moving, while the Schwarzchild solution is actually static with respect to a properly chosen time coordinate (and without checking, probably the spinning and charged solutions as well). The spacetime is curved in such a way all timelike (c or slower) trajectories go inwards.

Do a hecking piracy. Problem solved. Personally ripping stuff from YouTube isn’t even illegal.

He’ll never be my Mario.

I haven’t watched it yet, but this basically confirms my suspicions.

It kind of did just wander.

I agree, it’s a fairly productive social science, but is there actual evidence that psychology has made an impact in organisation and management?

There’s plenty of anecdotes and some hard numbers that suggest management is replete with bullshit artistry. For example, most office managers rely on in-seat time as their only measure of productivity.

Mmm, I find it really handy to know that my memories are generated rather than recalled. Sometimes, I remember something that didn’t happen, and I know not to be weird and insistent about it. That hiding things from yourself is a really effective way to manage temptation is also not what I would have expected.

I’d actually say that by social science standards psychology has an above average number of applications.

I couldn’t actually tell you what all the Gates foundation does. Greedwashing exists, but as you say I don’t think Gates is doing it.

It gives away way too much to serve either purpose well.

I mean, according to this, the plan is to not be a billionaire. If his net life transaction ends up being bilking Western technophobes to pay for mosquito nets and clean water that’s cool.

Poop-de-loop.

The entire field isn’t therapy.

“Must be at least this rich to ride”

Best of luck!

What about just the bandwidth and storage requirements? Any news on that?

Yeah, similar weather relatively speaking.

I’ve never been to Toronto, so I can’t talk too much trash, but I have been to Vancouver many times and experienced how awesome it is. And, they both cost a similar amount!

Third-party or self hosted GitLab FTW.

Youtube is kind of hard to replace, though. There’s attempts but I’m skeptical they’ll go far.

Privacy, food safety and environmental regulation basically mean Europe, but then Europe has crazy anti-migrant sentiment at this point. So, maybe one of the Scandinavian countries that’s still relatively welcoming? Portugal might also track, if you don’t mind a country that’s economically moribund.
