Similarly, gigantic galaxy superclusters don't really affect us in our day to day, since they are far enough away.
Technically, they do, but it's meaningless.

But it gets more complicated if you consider that gravitons can only move with lightspeed. So the earth doesn't rotate around the sun, but around the place the sun was 8 minutes earlier. That detail can also be completely disregarded on those scales.

Gravitons are a proposed particle in some theories but there's no evidence of their existence afaik. But gravity does "travel" at the speed of light.

The space time curve is already there, though? I was under the impression it was the curve that determines the movement of the earth.

Yeah that's the prevailing theory of gravity. Other theories may have gravity as a force carrying particle instead.

I find dynamical systems (and the associated chaos) fascinating. In the end only brute force iterative solutions come close to modelling n body. Without knowing all the interacting factors (which we dont) the best we can do is a best fit. Kind of like predicting the weather.

The star system of the San-Ti would never have produced its own planets, so I guess their homeworld must have been a captured stellar wanderer?

Well... if we imagine the sun suddenly vanishing, that would obviously change the curvature of space-time. But that change would only reach us 8 minutes later. Until that happened, the earth would keep circling the now vanished sun.

Yeah, otherwise you could make ftl communication via gravity waves. Which would be badass as heck, but unfortunately not possible.

Caveat I'm not a physicist, so I may be wrong on the specifics here.

The very brief explanation is that there are two currently "incompatible" theories of how things work. There's general relativity (GR) which can be used to describe systems at very large scales like planets and galaxies. This is the framework where gravity is due to curved space-time comes from.

Then there's quantum mechanics which is actually how things work as we understand it, which is that everything is "the wave function" (with different interpretations on what this actually means, which is far above the scope of what I can explain). Quantum mechanics requires that forces be mediated by a force carrier. Light, part of the electromagnetic field, is mediated by the photon for example. The graviton is a/the proposed mediator of gravity but this has thus far never been observed.

E: incompatible is in quotes because the existence of one does not negate the existence of the other.

This is why i embrace hardcore Instrumentalism/scientific anti-realism, which holds that scientific theories are just models that we can use to predict the natural world, and that science makes no statements about what actually exists. Is it a particle? Is it a wave? Doesn't matter, it's all made up.

This is less of a philosophical position, and more that it freaks me the gently caress out to think about wave/particle duality and quarks and bosons, so I like to pretend none of it is real.

Apparently yeah, if the bodies are too small they can be disregarded. Like if you have a planet and its small moon, it behaves (close enough) as just one body.

At least that's what I got from this video with Neil deGrasse Tyson: https://www.youtube.com/watch?v=6GfIDwwxfsM

Most of engineering is looking at a complex equation and removing 3/4 of it because it's so small it will have no discernable effect on the result.

They don't get into it in the show, but yeah, the San-ti do eventually get to the point where they can accurately predict chaotic and stable eras. But then they discover another problem, which is that their planet is eventually going to spiral into one of the suns.

There's another thing that they don't mention in the show that is also kind of important. The giant human computer actually worked - mainly because the San-ti have dozens of limbs and can do complex calculations in their heads quickly - but it failed to account for general relativity.

Wasnt the computer thing because the santi communicated with brainwaves or something?
Also the reason they couldn’t lie?

I think it's because they are mirrored and can use light to communicate with each other.

watching this right now and Davos Seaworth is worried that an assault on the Judgment Day could lead to heavy casualties and potentially damage the data they're looking for. So instead they ... slice everybody in half with enormously complex nanofibers and just hope said nanofibers miss the data core?

The slicing is so thin that you can recover data from a sliced HDD (book knowledge iirc)

I haven't read the book, but just picking up stuff from the thread, the reason they did it that way was because if the drive was cut by a nanofiber, it would be such a clean cut you could put the pieces back together and stuff recover the data. The show's decision to leave that bit out does make it seem like an overly complex super villain way to destroy a ship.

The argument used in the show is that they needed something that would disable the crew so fast they couldn't react or destroy the data, which doesn't make sense, because Jonathan Price was still able to get to the drive, and no doubt could have destroyed or erased it if he wanted to, instead he took it for a walk.

lmao iirc in the book, it was supposed to take like 30 seconds so people wouldn't have time to process what's happening and respond. But the clocks in the command center definitely show like 2 minutes.

At this point I'm kind of doubting it's coming. The series hasn't exactly lit the world on fire and subsequent seasons will only be more expensive and alienating to viewers. Netflix is probably weighing up wether it's worth it and coming to the conclusion it isn't.
