Babylon 5 taught me the answer to this!

When a craft explodes it has an atmosphere, or the components necessary to mix and create said atmosphere, in the craft. At the very least mixed around the pilot in some capacity.

Different species with different atmospheres may have different coloured explosions. Example, for us it'd be yellow/orange/red. The typical colours we associate with fire. An enemy might have green explosions, or blue.

Further - there would be sound. There is a hot ball of expanding gas coming from the explosion, moving in all directions. It wouldn't be as loud as an earth explosion would be, but certainly some air particles from the explosion are going to hit your eardrums

ForceUser128 t1_ja29lrl wrote

Due to distances involved though, any sound would be delayed similar to a lightning strike on earth, but much worse because there is no real medium for the sound waves to propagate through but rather the atmos and molecules themselves moving through mostly empty space.

Also, at best, you might hear a thud rather than an explosion due to you being contained in a sealed, pressurised container (aka a ship). And even then, it'd more likely be from solid debri rather than from the very sparse (comparatively) atoms and molecules of an explosion.

exceive t1_ja3crwu wrote

You might hear something at the same time you see it. That would be the sounds your ship makes when a whole bunch of electromagnetic energy hits it suddenly. Maybe a rattle or thud as your hull abruptly and unevenly expands just a little bit from heat. Maybe some weird noise if your ship is accidentally a radio receiver. A lot of things are accidentally radio receivers if the signal is strong enough.

ForceUser128 t1_ja3jrw6 wrote

True, didnt think about other forms that 'light'(radiation) can take, like radio, xrays, etc and what effect that would have on the ship itself.

codeedog t1_ja3000m wrote

There would be no sound in the vacuum of space unless the two ships were next to each other. The gas molecules would dissipate rapidly. The density of the gas ball would fall off at around 1/r^3. The energy of the wave front would normally expand at 1/r^2 in an atmosphere which provides a medium for energy transfer. However, in space and without a gas medium, the “sound” must travel with the gas or other materials from the explosion and they dissipate rapidly (r-cubed) or stay as chunks of broken spaceship.

So, unless a chunk of exploded spaceship hit your ship, you wouldn’t hear any sound.

There's a sci-fi book series, the ember war saga, that actually takes this into account. In the book, when entering combat conditions, they will actually suck all the oxygen in the ship into holding tanks so a hit won't cause explosive decompression and the issue of fires for damage control tapers off. Seems obvious to a point, makes you wonder the viability of the strategy irl.

The sheer power that those vacuum pumps must have had to evacuate a resonable part of a big ass vessel of all the gas in a very small amount of time must be incredibly high even for times with space travel technology. Let alone the power neccessary to operate these things. But this never seems to be a problem due to some new fancy energy source.

They did this in The Expanse as well. Prior to starting combat operations they’d suit up and pump air to tanks. Space being large they’d typically have plenty of time to see trouble coming or start some.

GoodbyeSkyPrime t1_ja36plt wrote

Good question. In depressurizing, you have effectively 2 options. Vent your atmosphere into space, or pump it into tanks. In The Expanse, there isn’t a technology to manufacture atmosphere. Venting atmosphere into space would make it unrecoverable and would be very bad for everyone involved. The only option would be storing it in tanks for later repressurization.

In the series, the premise is that an alien. Oalition sends an envoy to earth to help prepare them to sidestep destruction by an extrgalactic extinction event. Part of this is the sharing of advanced technology so you could go from modern day tech to gauss weapons, space navies, and 15' combat robots with human integrated controls. So they probably could easilly bullshit an excuse up for the vacuum.

If movies were realistic they wouldn't be as entertaining

erpupone93 t1_ja1yos5 wrote

I disagree. Interstellar, as an example, is produced by Kip Thorne, a theoretical physicst who has also won the Nobel prize. Him and Nolan worked closely to make sure every detail of the movie is scientifically accurate. That Blackhole sequence took months to produce and the imaging was so accurate, that even science community started using it as a source to illustrate blackholes, since it was many years before we caprured the first ever image of a blackhole. If "entertainment" was the sole purpose, CGI and green rooms could have created visual effects that may have been more engaging but less realistic.

"2001 a Space Oddysey", one of the greatest films of history was shot: 1. Before we landed on the moon, 2. Before CGI and even computers were a thing (computers existed, but that's beside my point). Every detail in that movie is very realistic. There could have been ways to make either of those films more thrilling just for the sake of it. However, priority was given to realism, hence why after more than 50 years since its release, it is still relevant and even more entertaining than all new sci fi that's coming out every year.

There are many factors that can hinder "entertainment", but realism isn't one. And if a movie is realistic but not entertaining, it's not because of the realism of it, but a combination of other factors.

19

kinokomushroom t1_ja22oga wrote

Just a small correction, not every detail in the movie is scientifically accurate, such as the wormhole scene, which was only accurate on the exterior visuals and not on the inside traversal part. I agree about realism being important though. Interstellar is still one of the more scientifically accurate space movies out there and it's also my favourite movie.

16

sailorlazarus t1_ja245re wrote

I mean. To be fair. Interstellar did have plenty of nonsense.

"Love is the only force that goes beyond gravity, space and time, love is a higher power that supercedes mankind's understanding."

The planet in a stable orbit around a black while is extrodenarily unlikely but not impossible. Somehow, catching up to and landing on that planet, not happening with anything close to the tech in the movie. Even the tiniest error in orbital/entry velocity would send you straight into the black hole. And of course, the whole surviving a fall through a black hole. That's just a no under any reasonable circumstance.

An artificial wormhole that is stable enough for data transfer. Which even in theoretical models requires matter with negative mass.

The frozen clouds that somehow still stay in the sky... yeah.

Don't get me wrong. Interstellar is a good movie. But to say that every detail of the movie is scientifically accurate is wildly inaccurate. Plenty of the movie is scientifically accurate (the imaging of a black hole you mention is a shining moment), but it still takes plenty of liberties as well.

Your well informed protest is correct. But this one movie is an exeption. Every other sci.-fi. movie or show involving space travel uses some kind of made up bit of technology to work around laws of physics that (atm) makes long distant space travel impossible or at least unbarable.

bookers555 t1_ja3dihx wrote

In Interstellar they literally went out of their way to remove the doppler effect from the black hole's accretion disk to "avoid confusing the audience", there's a traversable and stable wormhole, and it seems no one who worked in it there knows what a Tesseract is.

Interstellar has very little in terms of scientific accuracy, feels like a movie made by someone who just had a spark of curiosity over space and just read bits and pieces of a bunch of Wikipedia articles.

The only accurate thing in it was the original black hole model, and that they refused to use it.

Almost all conventional bombs and missiles will explode in a vacuum, they don’t use atmospheric oxygen. But they wouldn’t work the same way without the blast propagating through air. A hand grenade will still explode and fling shrapnel around though.

AEMxr1 t1_ja1u8kg wrote

I would assume a grenade would work in a similar manner, but minus the gravity resulting in different speed and different types of dangers in the area, continuous as it may be. The explosion itself would have a smaller radius outside the container. I’m not sure if this would be something visible for longer than a split second depending on how far away you are in space.

exceive t1_ja3b634 wrote

The billowy puffy cloud effect we're are used to would not be present because it is the atmosphere pushing back that causes it. In space, each bit of debris would basically keep going in a straight line. Really an orbit around the local gravity well, but it would look like a straight line.

Watching the LEMs take off from the moon looked funny to me as a kid. The initial blast didn't billow. It didn't look like a blast so much as a bunch of sparks. I've been thinking about this get a while.

Actually, there could be a little of billowing, depending on how the ship blows up. If the blast starts with a relatively slow expanding has cloud and then later (possibly just a fraction of a second later) there is a faster expanding cloud, there might be some billowing when the fast has catches up with the slow. That could happen if relatively low energy stuff like the hull, cargo, life support, for example blows up first, and then high energy stuff like fuel and weapons blows up. Besides moving faster, secondary blast would probably be hotter and brighter.

I painted a space battle scene for a school project. The professor wanted to take points off because on one of the space ships had a small trail of fire.

There are so many things wrong with most space movies, someone could write a book about the drivel one sees onscreen. For example, most space movies have magic gravity that does not exist in space and their ships magically have it. They also often bank their ships flying in space, as if they were using wings in an atmosphere. They ignore the reality of distances and the impossibility of faster than light travel, the fact that hitting a spec of dust at anything near light speed would obliterate the spacecraft, etc.

Most "science fiction" movies about space are more properly thought of as fantasy films rather than SCIENCE fiction, because they have little to do with science.

The show The Expanse actually does a decent job with space physics. Ships are configured like skyscrapers and create gravity when they thrust.

90 mph is almost nothing.

To help you understand, think about tossing a bullet back and forth with a friend. You can do that without your hand getting hurt at all, because the bullet is not going very fast. However, that same bullet being shot from a gun is going very fast coming out of barrel, and it hitting your hand at that speed makes a very significant difference for how it would affect your hand if the bullet hit your hand.

And the speed of a bullet out of a gun is practically nothing compared with going near the speed of light; the forces involved are vastly greater with vastly greater speed.

The speed of light is 300,000 km/s, or about 671,000,000 miles per hour. Quite a few orders of magnitude larger than 90 mph.

The kinetic energy of an object depends on both its mass and its velocity. A fly against your car is light enough, and the velocity of your car is small enough, that a collision between a car and a fly does nothing to the car. Once you approach lightspeed though, even a speck of dust could wreak havoc

It would not be as loud or travel as far as an explosion in an atmosphere, but within a certain distance you would hear it. Further, sound propagates very well through metal, and spaceships generally have atmosphere inside them. If something hits the spaceship you're in, you'd hear it. If something explodes close to your ship you'd hear it. You'd also absolutely be able to hear weapons firing, engines operating, and anything else that vibrates on the ship you're currently in. Any engine that creates a pressurized exhaust would be audible from outside as well, though in most cases I'd imagine if one were close enough to hear it they'd be killed by it because of temperature or radiation.

Last week I watched a particularly bad sci-fi movie called “Deus, The Black Sphere”; my Netflix deliveries have been out of whack for a few months now, so I stopped at a local library branch to get a couple movies, and while I’d never heard of this film before, it looked worth trying for free.

It was painfully derivative of a thousand SF movies that have come before it, and filled with so many standard SF bad science tropes, including suspended animation hibernation/“hyper-sleep” pods (these just for the trip to Mars from Earth, to boot), artificial gravity that isn’t at least visually explained by centrifugal force, instantaneous remote communications between Earth and a spacecraft in Mars orbit, people risking shooting solid projectile firearms inside a spacecraft, and undoubtedly a few more I don’t recall right now. The movie was so bad — writing, acting, plot, basic premise — I got probably 80% thru it but cared so little about the characters or story that I finally just turned it off.
