I'm fine with sci-fi being completely unrealistic. I mean, like many, I loved Stargate! What I really dislike though is when sci-fi pretends to be realistic while being blatantly incorrect about physics. Because that's not only dishonest, it is how you get the worst misconceptions into the minds of the general public. That just makes me mad.

Bingo. Just be honest, and I'll be more than happy to suspend disbelief, if you're telling a good story.

The only way I can think to make a killer asteroid movie (or show) be interesting again would be if it was set in the 1960's. Then there would be a good explanation as to why we have a low velocity impact we didn't see until it was almost too late, the tension of the US and the USSR being forced to work together would give plenty of intrigue, and of course this would be an excellent excuse to have famous astronauts like Neil Armstrong and Yuri Gagarin be stars in a modern movie.

Do what I did years (no, decades) ago: Throw over entirely ANY idea of learning real science FROM sci-fi. That is NOT what it is good for. What Sci-fi does best, is to ASSUME some "science" or future state, and then explore what happens to "normal" people and situations if you carry such an assumption through in the story (no confusion here: it's just a STORY). But as to "rockets don't work that way," why stress? That's not what the story is about, it's just a bright crayon to add color.

[@rhamph]

Some of this is solvable! Just assume the altitude during the launch sequence is entirely accurate and they built a 20 km tall rocket, then figure out if the mass of said rocket is enough for the gravity tractor. :D

[@RainaThrownAway]

Now I want to write a book or a movie that follows a similar premise - someone finds something weird in the data, announces that an asteroid is going to hit the earth and wipe out all life, and give a short time frame - 180 days or so. Focus on everyone freaking out, the human element, people killing themselves and their families, or collapsing into despondency, all of these frantic things happening... and then the asteroid misses the Earth, because the guy was just wrong. And the moral is about responsible reporting and considering that hysterical reporting often does more harm than good, because now they have to clean up after the hysteria.

[@DatAlien]

180 days is plenty enough for better observations and tabloids have predicted our asteroid related doom in past without any collapse.

[@PyroDesu]

No. The vast, vast majority of telescopes amateur astronomers use (bearing in mind, most won't even go as far as 12-inch diameter, and diameter is what determines light-gathering power - bigger diameter = more light = seeing dimmer objects. Don't even begin to consider magnification - even the four Gallilean moons in a 12 inch telescope with an 8 mm eyepiece and Barlow lens appear as *point sources*) can't even see Amalthea, the 5th biggest moon of Jupiter (250 km x 146 km x 128 km), and the last satellite discovered by visual observation (by one Edward Emerson Barnard, who was working at the Lick Observatory at the time, with a 36-inch telescope). Funny enough, there *is* a 7 km diameter moon of Jupiter - Praxidike, discovered by a team of astronomers from the University of Hawai'i headed by Scott S. Sheppard in 2000, using the University of Hawai'i 88-inch telescope at the Mauna Kea Observatories. Source: I'm a member of the Barnard Astronomical Society and regularly use a 12-inch telescope, often looking at Jupiter while it's up because it's one of the more spectacular targets to show people. That and Wikipedia for most of the actual data.

HELL no. A 7km asteroid next to jupiter is less bright than the planet by a factor of more than two trillion. That's like seeing one cigarette ember against the backdrop of an exploding Hiroshima-size nuke. . A telescope in Hubble's class, with weeks of observations, *might* see it. .

Go easy on the CGI team. Many people who work in this area (like myself) are serious science nerds, dot product vector maths used in light path rendering being an example of what I mean. Chances are, someone in the CGI team would have politely pointed out that Jupiter was nowhere near the asteroid but the producers/art directors would have told them to shut up and deliver what they were paid to do. The fact that a respected science bod was consulted, and obviously ignored/overriden in many cases and what I know of the typical production process leads me to believe this. However, this is one of the less egregious examples of ignoring reality, given that people don’t want to see a screen with tiny distant dots on a black field in their TV shows. A similar argument could be made for the exploding EM ‘drive’. A big explosion is much more ‘cinematic’ than a simple burnout. The falsity in the orbital graphics and launch display of 10km in 3 seconds are another story - there is no argument that falsifying reality improves the story in these cases. And that’s the 2D compositing team, a different lot to the CGI people. Even so, there’s probably some story of a demo that was liked by the producers who didn’t want to bother creating an accurate final so a dodgy demo was overlaid on the screens and ended up in the release. The producers are responsible for everything wrong here - the poor saps who do the actual work typically do as they are told, being subcontractors and freelancers. The traditional, so called creative types typically wear their science ignorance on their sleeves, although this is getting better than it used to be 20 or more years ago.

Saimons ... To be fair position, speed and acceleration of very distant spacecraft are being determined down to the 5th or 6th decimal place in m/s. The Pioneer anomaly was detected when the spacecraft was about 100 metres off of its predicted trajectory all while being 30+ AU away from us. Things like determining the density of Europa and Enceladus were done by carefully tracking acceleration of spacecraft that were 5 and 10 AU out from the sun. Of course, on the other-other hand, these were measurements taken of highly instrumented spacecraft that were broadcasting on known radio frequencies. Asteroids are lumpy, bumpy chunks of stuff whose composition isn't precisely known so measurement error bars are going to be much larger than for spacecraft we built ourselves.

I think 30 hours of ksp should be mandatory in every middle school. globally. with a teacher that explains how and why this shit works. the project end goal, land a rocket on the moon by the end of the week in a space-race sorta thing. allow the student to walk around and spy on each other for bonus realism.

[@nombuso484]

[@kallewirsch2263]

Another idea: Since the earth represents a moving target, in the best case you "just have to delay" the asteroid. Earth moves with ~30km/s, the earths diameter equals 12000km, so if you manage to delay the arrival by 400 seconds, the asteroid will miss earth. When the asteroid reaches the "impact point" earth simply will no longer be there. Of course this would also work in the other direction. Instead of "braking" the asteroid, speed it up such that earth will not yet have reached the impact position, when the asteroid passes. Thus by choosing either acceleration or deceleration you would have to manipulate the asteroids traveling time "only" by a maximum of 200 seconds.

[@scottmanley]

+kallewirsch2263 and if you do the math it turns out that you need 0.42m/s to do that. Spooky eh?

[@kallewirsch2263]

Ah, this is where this number came from in the video! It was not clear to me how you came up with it. I thought it to be some sideways acceleration to bend the path. Thanks for clearification. (and you are right. I have not done the math. mea culpa)

[@lubey111]

I think what Scott is saying is that the extra velocity you need to apply to the asteroid can be in any arbitrary direction, including forward, backward or sideways. Distance = speed x time, and the objective here is to cause a certain change in distance of the impact point in any direction, within a given timeframe.

I guess then they probably should have nuked it.

[@wilkins67890]

Nuking it is an idea that would work though so we cannot have that in our super dramatic sci-fi show

[@radiofrog]

Season 3: The astronomers didn't realize it until now, but Jupiter had been knocked off course by the 7km asteroid and is headed straight for Earth. This time they only have 60 days with Russia and North Korea simultaneously hacking both the spacecraft and Jupiter itself. The protagonist must now construct a NUCLEAR EM drive to atomically attract the gas planet out of the solar system, for it is the only chance Earth has at survival...

So just how many rocket engines placed on opposite sides of earth would we need to spin the planet up until it flew apart?

[@stargazer7644]

Far, far more than all of them. Increasing the rotation rate of the planet to once every 84 minutes would put everything on the surface of the planet into orbit.

[@patrikhjorth3291]

This reminds me of the Matrix. In the movie, the Machines want to keep the humans "bottled up" to use as generators, harvesting our body heat (among other things) to generate electricity. I read somewhere that the original idea instead was to use our brains as processors, to run all of the software on. Humans would essentially be hosts to the machines, and every person disconnected would be like one shelf in a server rack going dark. This would make just a tiny bit more sense, assuming that you accept the basic premise that people can be seamlessly connected to computers, but someone decided that the "electricity" version would look cooler on film. I would assume that many of the things wrong in shows like his come about for the same reason: the real thing wouldn't look as cool, or be less comprehensible to someone without a background in spacerocketry.

[@AthAthanasius]

To repeat myself from Twitter: Just part of why I gave up on this show before the final two episodes. Had to save myself from fatal facepalming.

[@IneptOrange]

That recent comet from interstellar space a few weeks ago, I find it super cool. (I mean it probably is with the ice and all), but if there are lots of these events around the galaxy, it suddenly becomes a massive game of interstellar pinball with thousands, maybe millions of tiny rocks trying to get to the center of the galaxy as fast as possible.

I feel bad for on site advisors. Lindybeige had a friend who was an advisor on a medieval film. They only asked him one question... "Would the army marching along have this flag in front of them or in the back?", to which the advisor replied, "That's a cavalry standard.". They then walked away from him and never asked him anything again. As for the whole "Oooohhh big spooky rock gonna hit us" thing goes... well, we've been hit with tens of thousands of them. Some were pretty big too, but we're still here. :)

[@Crushnaut]

[@MonkeyJedi99]

Nah. A train wreck uses real physics.

[@dinoschachten]

Ouch!!! And I got upset when Clooney's character in Gravity pulls on the ropes is if there was inertia at work even though being completely stopped by said ropes. Being a filmmaker myself, I cannot possibly understand why writers insist on going the absolute-bs-in-your-face route when a couple more minutes of thinking could have brought a slightly altered, perfectly believable scenario... I mean how do you sell this stuff to your own team??? I mean I get embarrassed when I realise that I forgot to film that shot where a character walks up to the other guy so there's a motion gap between two shots (and even more so if one of the actors points out that the logic of the motion does not quite add up). And there they go, working with experts and telling everyone to just swallow 7 kilometre asteroid worth of in-your-face bullshit... that's just embarrassing.

[@TheWindigomonster]

So could you knock it in a spot that would make it rotate fast enough to break apart?

[@bratimm]

Then you would still have all that mass on pretty much the exact same trajectory.

[@TheWindigomonster]

Yeah but then would the chunks be small enough to burn up in the atmosphere or at least not annihilate the entire planet? My knowledge of astrophysics is pretty limited so I'm probably missing something.

[@Mythricia1988]

And now you have a Asteroid-sized shotgun blast heading for the Earth instead. This is exactly why nuking asteroids is not a solution!

[@bratimm]

TheWindigomonster Even if they would burn up completely, the energy released per square km of the surface would be enough to heat up the atmosphere too temperatures way too high for humans. Scott even has a video on that ("why nuking an asteroid wouldnt save the world").

[@timothymclean]

1. Whatever you knocked it with to spin it would knock a chunk off the asteroid before getting it to spin hard enough to fly apart. 2. Theoretically, you could blow the asteroid apart far enough from the planet that the slightly-different orbits of the chunks were enough to make a significant percentage miss. 3. A 7-km asteroid won't destroy the Earth, it would just cause a mass extinction. I'm not sure some cosmic jerk throwing Mars at Earth would destroy the planet. The asteroid burning up in the atmosphere wouldn't be _as_ bad, but all the thermal energy and dust would still be bad.

*Gahaha I think nobody must have noticed what Scott intended with **0:40* He was doing the same thing as the convoluted plot for this episode did. "This is probably too boring for normal people so let's give them an information overload" Scott basically simulated this using subtitles for a secondary story as he narrated the primary story. True genius on his part.. however based on the comments I've read I don't think anyone caught it.

[@Dorianin1]

Yah, I got confused for a second there, I read the ACC one..

[@gjsmo]

One little thing I noted was that the change in density shouldn't affect the gravity tractor's effectiveness at all. At least, according to the law of gravitation F = G m1 m2 / r^2, the force the tractor exerts on the asteroid (and vice versa) would increase linearly with mass, which causes an equal acceleration via F = ma. So the mass of the asteroid is irrelevant, only the mass of the tractor itself matters.

[@Etheoma]

Well the first episode of Star Trek Discovery was pretty bad, they couldn't see it with there sensors but they could see it with there eyes. How does that work? Because they should have optical sensors just so you can get more data, then they go out of communication because the field is stopping them communicating even though the suit has lights on it and if you can see the lights you can send a message with quite high bandwidth certainly enough for audio communication. As long as you can track her that is and they could track her well enough to see that she was free floating... So fucking stupid.

I haven't watched it; is it possible that what they were seeing was being projected into their minds, and wasn't physically there in the normal sense?

[@brandon3883]

Based on measurements attained through precise instrumentation at the 11:54 mark of this video ("my fingers pressed against my monitor"), I've determined that the rocket is almost exactly 9 kilometers long. _Edit: I failed to take into account that the altimeter is probably in the nose, whoops. 9km seems the correct, corrected length._

[@52rhflight56]

Great job by the excellent Scott Manley video ... my only nit is that there is a limit to how far a show's producers should "stretch" science for the benefit of fiction, and only so far that we're willing to support that argument. The problem with any show that purports to be science fiction (SF or SciFi) is that it needs to have some credible basis to sustain the viewer's willing suspension of disbelief: the show's writing, production and creative premise have to deliver an enjoyable experience based on buying into its fictional premise in the first place. It's an informal deal between the creators and the viewers; break the terms of that deal and that willing suspension of disbelief bubble pops. There is a difference between a viewer's initial open-mindedness regarding the show's premise and the viewer holding on to the continued belief in that premise. Willing suspension of disbelief boils down to holding off on or postponing judgment regarding the credibility of the fictional story. For Salvation, they should just have called themselves "fantasy" and then used some self-consistent, arbitrary system of magic to explain the effects. IMO fantasy is different from "speculative science fiction." There are some that explain Salvation's script as "bending" the science to fit the necessities of interesting story telling. IMO there is so much completely wrong with known science in the script that the show needs to reclassify itself as pure fantasy. As an example, Scott Manley's video provides some good examples such as the zero-lag command channel and video feedback. IMO the departure from science in the show is an indication of laziness or carelessness rather than "necessity." That tendency reflects itself in other aspects of the story line, as well, leaving some gaping holes. The Salvation first season started with abysmal ratings and then got even worse. I'd like to think that the audience being smart enough to scoff at the show's science contributed to the ratings, but I am open to someone calling me on that just being more fantasy ...

[@kateapples1411]

This reminds me of a game called INTERPLANETARY. It's pretty fun. I don't actually own it but I remember playing it on a free weekend or something a year ago. It's like battleship meets Civilization. It's a turn based space game where your civilization on one planet is at war with civilizations / colonies on other planets and you have to account for the movement of all the planets and large objects when you fire to try to bombard the planets surface and hit their facilities. A late game super weapon was slinging asteroids from the asteroid belt that are hard to predict and slow but have huge areas of effect if they do. I played it for hours on end it was great. EDIT: Oh, Scott played it on his channel a year ago.

[@3DPDK]

Frankly, I stopped having any good expectations of any science fiction movie or series produce by the major networks since about 2003. This was when The Sci Fi channel changed it's name to Syfy to accommodate a young audience that couldn't spell or at least realize that scifi was a long standing abbreviation for science fiction. Since then most of what has come out of T.V. in the way of science fiction is full of technical holes that even the average high school graduate knows is ridiculous. Except for a few recent movies (and yes, even those have some technical holes), the last good scifi T.V. was Farscape and Firefly and one (only) season of LEXX. None of these productions pandered to the junior high school audience like NBC and Syfy (same company by-the-way) and now CBS have done for the last 15 or so years. Look at "Deep Impact" a Paramount Productions film, and one of the least researched films of all time with a plot centering on a couple of basically clueless 19 year olds. They couldn't even get U.S. geography right in this movie much less astrophysics. Frankly ... I'd rather spend my time playing Kerbal Space and bug laden, memory leaking, Empyrion, and watch naive '50's and '60's scifi movies.

[@Mitchz95]

The Expanse is a pretty good show. About on par with Firefly in terms of scientific accuracy.

[@3DPDK]

I've seen the trailer and it doesn't look too bad, but you know how trailers can be misleading. I'll have to take your word for it. I do like that the write up about it says the story centers around a detective in an investigation into a major government cover-up. This usually takes the emphases off fantastical technology and more onto the human aspect of the story line. It seems to be produced by Syfy so that makes me skeptical of it. If Syfi isn't producing it and just bought the syndication rights then it may have a decent chance of being worthwhile. I don't even own a T.V. anymore so I'll have to wait for it to show up on Netflix or Hulu or something. Thanks for the heads up.

[@solarisone1082]

Firefly is a good show, but it's not very scientifically accurate.

[@rohanpotdar908]

Wait, isn't Deep Impact, like, ancient?

[@ScribblebytesWorldwide]

As a film grad I can tell you that sci-fi is about Moral Dilemmas. That's the narrative drive of sci-fi shows. That's why it's called Science *Fiction* Its not meant to be a lecture but a backdrop to study human moral behaviour. That's it. The characters explored in the show present different moral values. That's the point. For all I care, the asteroid could have been a block of cheese I don't care. It's people like this who are ruining shows chances.

But I would like to see a movie or show where they exploit the narrative and dramatic potential of the realities of space travel and physics.

Things have improved since the late 70's when a made-for-TV movie showed a comet coming down on Phoenix, AZ, for several days.
