Yes, I do know that. My doubt is: The scientists at Earth, stated that they spent 50 years receiving signals and info gathered by the scientists on the planets. Now think about it, how much information would you gather in 50 years? A lot, right? So Earth knows a lot about the planets outside, but the thing is, it passed 50 years for people on earth, but mere days for the scientists on the planets. The scientists did not spend 50 years gathering info, so how did earth receive 50 years worth of data?

They didn't. They received a few hours of information as transmitted by the scientists, redshifted 61320-fold by gravitational time dilation owing to the nearby black hole.

So basically they received a few hours of data, but ir arrived so slowly that it took 50 years to finish?

Yeah, there's plenty of information out there, but you don't need that information to form an opinion and then defend it to the death.

Exactly. They may have gotten more from a longer range, though; the strength of the dilation is inversely proportional to the distance to the massive object. (I haven't seen the film either.)

So if they leave what I'm assuming is a wormhole and fly straight down to the planet, transmitting all the while, you'd get long-range imaging in real time, with the observed dilation increasing as they got closer until it reached the aforementioned Lorentz factor on the surface.

Well, thank you. But now my life has no more meaning.

My most sincere thank you, and also... I'm sigging this

I thought the people on earth didnt have data about the planets because they could only get a plain “still here” signal through the wormhole or something plot-based

The paradox would continue, because then, earth received 50 years of "still-here" signals, while acctually, only a few days of signal has acctually been sent.

It's been a while since I saw it (when it came out), but I think it was a basic confirmation signal. They knew they couldn't get high bandwidth, they may even have had a mediating probe receive the (instantaneous-but-drawn-out) planetary signal, deal with its temporal issues and further help to extend its range back to Earth by acting as a latched relay.

IRL, the Voyager craft are working at around 160baud, currently, though they may have been faster during the Saturn encounter, apparently the location of this end of the wormhole. There's strangeness in passage through the wormhole, then the issues of travel from the other end. It is conceivable that even with current/near-future improvements to probe/spacecraft communications, the far end (and middle) of the outreach is already problematic, before the extreme doppler-esque slowdown.

If a full-handshaking mode could be established, then status updates might be prompted for (even if it takes a while), but I imagine the inflexibility of the transmitter (may only be able to ramp up its frequency so far, possibly only to the limits of the sending circuit, requiring the earth receiver/relay to adjust down to the ultra-low frequency it still would become) means that it may have been designed to be more UDPish than TCPish in its protocol, given how abnormally latency-tolerant it needs to be.


(I'd tell you a joke about UDP, but I'm not sure you'd get it.)

Didn't saw the movie, but i would guess the speed of the signal was distorted by the wormhole too.

Imagine you are sending me as bluray copy of Interstellar to me here via a file host(the wormhole), your upload speed is 1gbps thanks to google fiber, so you are done in a few minutes. On my side, with a 256kbps I'll have to spend days/weeks down loading it.

I'm curious as to how a tank would evolve. Would it climb out of the primordial ooze wiggling it's track-nubs, feeding on smaller jeeps before crawling onto the shore having evolved proper treds?
My ship exploded midflight, but all the shrapnel totally landed on Alpha Centauri before anyone else did.  Bow before me world leaders!

Japanese declare war on SPAAAAACE!!!
I thought it was going to be a repeat of India's bright idea to launch a missile at a satellite in Earth orbit, destroying it and potentially threatening the ISS with debris.

First, we need to send George Clooney and/or Sandra Bullock up there for that.

Because it's been done and probably won't help with our constellation of orbital debris one bit, but it hasn't done what it did to Clooney et al (it still could cause a cascade, but then so could any other random bit of debris that was already there).

What I find most worrying is, as seemingly revealed by the shuffling of participants in that spacewalk the other day, they might not be able to put everybody in a space-suit in an (slow-enough developing but inevitable) emergency. One sort of assumed they had kit enough for at least transfer between modules the wrong side of a breached central hub, should they find themselves needing to, without needing to do double-duty with some of them (undonning them and getting a still-suited colleague to take them back for the next wearer).

So maybe in such a slow-emergency they'd make do with slightly awkward sizings, and less fuss about the need for comfortably-fitting equipment for extended work, but emergencies don't tend to even be that slow (Russian-style microleaks aside) so you tend to imagine there'd be a set of good-enough-to-leap-into suits of at least the same number as the crew (but ideally a multiple of that, sets placed round the rig in whatever spare internal space they can cram them into).

Or maybe it's just not worth it given the number/proportion of scenarios where the emergency is basically so quick there's no chance at all of doing anything about it. Cost/benefit actuarial analysis doesn't justify the space and weight needed, so they only have two each of the US and Russian 'spacewalk' suits, and would rely on their individual limited-protection 'travel' suit for any very brief episodes of depressurised exposure protection (no real thermal maintenance or micrometeoroid-armouring)..

It's a corner I'm not comfortable to find being cut. But I'm not the one trained to take account of the risks.
