"Helium fuses to produce Hydrogen" - you WILL not hear the end of this!😂😂
Heh heh…
A cursory check of the comments section and…. Yes. He has gone viral.
LOL I completely missed that!
and neither should they. sloppy crap money-spinning pretending to be educational
i immediately went to comments after heating this lol
That's probably why they made such an obvious "mistake". Baiting comments is practically required for the algorithm
The Expanse is phenomenal. It proved you can still have action, drama, and suspense in space, but still be scientifically accurate. That IS the suspense. Physics practically is a villain, a hero, and a secret weapon by itself.
I was actually a bit upset and disappointed when (Spoiler!) Naomi jumped through the vacuum of space without a vac suit without drying.
Just shows how feel this misconception runs within most of us.
@@sonneh86 same
Yes the Expanse is amazing, way more accurate than other shows and movies but it does make some compromises.
For example the ships would need huge radiators and heat sinks, plus they do have sound effects for space sequences.
Firefly actually had no sound effects for its space sequences which though it is on the whole much less realistic than The Expanse actually makes it more accurate in that one regard.
Boring
@@sonneh86 To be fair, it did nearly kill her.
Minor correction Simon. I heard on April 26th that Voyager 1 is back online and communication with earth. In general, software engineers discovered one of the computers had areas that were corrupted and after re-uploading the software / coding using areas of other computers, Voyager 1 started communicating again. The signal (travelling at the speed of light) took almost 23 hrs to reach Voyager 1. The round trip signal (travelling at the speed of light) took almost two days. It’s amazing that both Voyagers are still working and communication after almost 48 years.
It's comical that you actually buy into this insane bullspit....you think that we can communicate with something billions of miles away yet my cellphone doesn't catch signal from 50 yards off the hwy? You are SMOKED!! The indoctrination is strong with you sir.

Wow almost 50 years and not even a light day away!!! So I’m assuming it’s going to take about 183 years before it’s a full light year away?? Amazing how small we really are in this massive galaxy 🌌/ universe !!!
@@SovietMOB 18250 years to be 1 light year away.
@@dpsamu2000 yeah I must have been on one when I typed that 183 years clearly 50 x 365 is more than 183 !!! I’m scratching my head because I have no idea how I even came up with that when I have a calculator!!!
Actually, the tree falling in the woods with no one around to "hear" it, still causes air molecules to be moved in waves. The presence of ear drums is not required for the physics of the air molecules to be moved by an object. It's the same as tossing a rock over your shoulder into a pond while not looking at the water. The water reacts with waves regardless of whether it is being watched or not.
a tree in the forest will always be surrounded by ear drums, they just won't be human ones
Just for a second I pictured a set of drums made from ears.
@@markc7955
badass
Even without a living thing to hear it, the sound is still created (and can be detected with a microphone)... This thing that if nobody hears it there was no sound is just BS.
Sound waves exist without ears. That’s like saying light doesn’t exist if no eyes see it. No. Photons are still traveling, just like air is still vibrating.
@@rdspam ~ Vibrations in the air aren't actually "sound waves" because sound is a mental construct, just as color, taste, smell and other perceptions are mental constructs. Referring to air waves as "sound waves" is a misnomer that begs the question -- because it assumes that air waves already exist as sound before the brain creates the sensation of sound.
Kudos to the editor for throwing a beret on Simon when he said "We're going to bust some myths". Even without the stash, it was a good throwback to Jamie.
I was looking for this type of comment, because i came here from watching mythbusters :)
11:31 Great news -- as of April 5, 2024, Voyager 1 is back on-line!!
Major kudos to the Voyager team, for figuring out what was wrong, and devising a fix.
You believe anything 😂
@@Kobe8DaGreat24 You disbelieve anything
It was April 20. And they just started doing the repair which would likely take weeks to complete. A bad memory chip containing some of it's software was the culprit. It caused it's transmissions to be garbled since November 14, 2023. They had to move that software elsewhere and change references to it in the rest of the code. The first of a series of software updates was completed on April 20. The repair is complicated because the software was too big to fit anywhere else. It had to be broken up and spread across different locations. Their first software update got Voyager 1 sending status information about the condition of the probe. An important first step.
Did they find a fix or did ET phone our home?
I'd say sound is the air vibrations itself, which can affect things other than ear drums, and the air vibrations from a falling tree are still there whether anyone is there to hear it or not. The actual definition of sound is "vibrations that travel through the air or another medium and can be heard when they reach a person's or animal's ear" which means air vibrations bring sound is not contingent on being heard, just that they could be heard if an ear was near.
Thank you. I just wrote something similar before checking if I was first.
Guess microphones don't pick up sound, just vibrations. This sounds like semantics not science
8:28 I think you misspoke. Hydrogen fuses to become helium, not the other way around that you said.
He definitely misspoke
Correct. And once most of the available hydrogen is fused to something else the helium will fuse to something bigger (IIRC beryllium), eventually carbon and oxygen will be formed by fusion and so forth - until iron is the result of the fusion. It all stops at iron because the next fusion between iron atoms takes up more energy than it produces. So when the fusion switches to making something larger out of the iron that's when the star is going to die (by that time our sun for example would reach a diameter of about the Jupiter orbit, so our good old earth is toast inside that red giant star our sun has become)... If it's larger than ten times our sun, it's going to go supernova, which is when almost all other elements we know will form again (we ourselves live off a supernova that happened more than 5 billion years ago - else we wouldn't have any other elements than anything below iron in the periodic table)
@@karlgunterwunsch1950 so eventually, unless the weirdness of "dark matter" somehow intervenes in an unpredictable manner, the universe will eventually consist of nothing but "iron stars" and black holes. And it may stay like that forever.

Oh, oh, very nicely done. *tips hat*
English holorimes are rare and wonderful, thank you!
so good

@@NeutralDrowyou should read the newspaper comic Pearls Before Swine.
Direct energy ejected from an explosion can still reach the hull of the ship you're in, as a stream (not wave) of energetic micro particles. This would allow you to, "hear the explosion", kind of. On the other hand, an energy burst large enough to do that will have distracted from the faint whooshing sound by the extremely loud sound of your ship's atmosphere escaping through myriad new tiny holes. Screw sound! :P
I feel like Fire Fly/Serenity was closer to being right without ditching the suspension of belief. The sound we hear is the equipment from which mechanics perform, kind of like swinging a hammer at a metal pole and it vibrates - that would travel through the machine, to you, to your ear but it would be a weird dull sound.
But imagine a movie or a game without, it's more as just boring without and you are never quite aware what happens around you, thus sound is for the entertainment essential and entertainment does not have to be real at all. Perhaps the approach to be isn't as good since the real sense of sci-fi is to cover social problems not the technology.
*dear reader* :)
"We leap with our social developement 100 year behind our technology"
H.G. Wells, War of Worlds 1898
It's not a novel about space or technology in this sense it's a philosophial novel about humankind.
the bloodsucking alien is just to bring us in an extreme situation in which the author pulls the mask from our faces and shows us the real monster.
And that is the root of it not accuracy in technological vision, vice versa Wells criticises it heavy that we think we are dominating nature with this weak technology we have and think we are the crown of creation due to destructive acting against mankind and nature.
I guess accuracy is rather a hemlock as needed to write good sci-fi.
Since heck, you know it's a novel and it starts as a continuing story of a columnist in a newspaper so it's all fantasy in a fantasy, he introduces chapters with "dear reader" nonetheless he is able to sell this fiction for real, you live through the story with the protagonist who is certainly the columnist in other terms Wells himself. It gives him the possibility to comment the drama while being part of it.
"we haven't deserved that nature saved us"
And whatever good sci-fi i have read the technology is only environment, for the real message of the story, a setup.
And pardon me since when do aliens exist?
Since war of worlds, it's a product of our (his) fantasy and we have zero evidence for it.
We could count Verne or Kepler to it but first has written only entertainment (yes i guess there is critic as well in blind faith in technology) which is good as well and Kepler liked to hide his theories, or wrap it in a story. Latter i haven't read yet to be honest.
For facts i refere to stellarium or to a science article, but not on a novel, movie or game related to sci-fi, that's a quite different topic and i don't know if that makes sense at all to wrap this knowledge then in a novel or movie or game, to a certain extend it's ok, but space is boring.
And please guess always of H.G. Wells not Orson Welles (resp. Howard Koch) Who is finally responsible for the complete wrong image of a possible alien lifeform we have which is so far from novels before this radioplay. The only thing left of it is the power of media but this is in the original novel only a tiny bit of the message in all. Whatever the intention was this was the result of it.
In the novel power of media is reduced to that you get the impression that this continuing story is reality, fake news if you like though, but "dear reader" always gets you back to earth. That is far from what Orson made out of it. He earned a grammy for it, killed a novel and made a whole genre rediculous through this and reduced it to spectacle even if that wasn't his intention, a bit unwise in my opinion.
War of Worlds is a war of head-worlds, and i might have read dozends but this i had to read three times and each time it moved me. you need time to think about all he states in it. Certain things you might refuse for yourself but think when you read it for the second time "yes i know i do that to".
*It seems we don't mind to be literally held as cattle as long as we have food and sex enough*
The wonder in it is that he creates rage against yourself instead of hoplessness.
It's not "humans are shit and i can't change this"
It's "i know it's part of our nature but i don't like to be like this!"
Most of all it isn't "arrrrrgh bloodsucking aliens"
The protagonist admires them because they operate social, there is no inequality and the goal is to survive as species.
Their planet (Mars) is sustained and they only look for a way to survive, while we destroy our own source of life for something questionable as personal wealth especially if that exceeds the to imaginable.
And this we would need so much today, instead of giving it up before we started.
200 years, Mr. Wells, 200 years by now!
So far to the sci in this fi.
Projectiles or saucers doesn't matters at all.
In the novel they arrive with projectiles, the first he saw broke that's why you dear reader will know how they might look like. He got closer and knocked with his pipe on the cylinder... (still in night-robe and slippers on the way to get his daily newspaper, eh philosphists don't like to get up early in the morning).
It's really a fantastic story and no matter 19th century you are in the time and the place, i guess the language plays a big role, it differs much.
0:55 - Chapter 1 - Sound doesn't exist in a vaccum
2:30 - Chapter 2 - Explosions in space
4:45 - Chapter 3 - A human body will freeze or explode in space
7:10 - Chapter 4 - The sun is a burning fiery ball
9:55 - Chapter 5 - Flying through an asteroid belt is dangerous
That Total Recall scene might be completely inaccurate... but DAMN it was a genius bit of movie magic!
It could be accurate if the Mars colony had a much higher pressure. Explosive decompression is explosive. Do not lookup the _Byford Dolphin_ incident.
well, asphyxiation is true xD
Everyone's always trying to ruin our fun! Suspension of disbelief is a wonderful thing. I don't care how inaccurate that movie is. Even as a huge Philip K Dick fan I love that movie.
I feel like the most absurd line from Total Recall is often overlooked. "The entire core of Mahs is ice. The reactah melts it... and releases the oxygen." Yeah, no and no.
1. A planet of rock is not gonna form around a less dense core of ice in the first place. 2. We can't breathe water vapor. Melting ice does _not_ separate the oxygen from the hydrogen. Earth had water for billions of years before there was significant oxygen in the atmosphere (slowly produced as a by-product by stromatolites growing in the shallows).
A couple of updates since Simon's team wrote the script: Voyager 1 is communicating again. NASA engineers told the onboard chip to disable the "dead" or damaged part and transfer the instructions to functional portions of the chip. Eventually, yes, Voyager 1 will "die". The other thing is that neither Voyager 1 and Voyager 2 have not left the solar system. Assuming they keep going, eventually they will enter the Kuiper Belt and indeed the system, but that hasn't happened at this time.
Voyager 1 left in 2012. It entered interstellar space.youre thinking of the Oort cloud not the keiper belt
@@cellanjones28 Oh yes, so I am. I was indeed thinking of the Oort Cloud.
@@cellanjones28 *_How The Universe Works_* did an astoundingly fascinating episode about it. It was the fourth season ("series" if you're British), and the episode was called _"Edge of the Solar System"_
(Sadly, season 4 is not available to watch on Discovery Plus, but I just bought the 4th season on my Amazon account, and I think it may be available to MAX subscribers.)
I just had to look up voyager 1. That’s insane they reconnected. It’s almost 1am and taking everything in me not to go down that rabbit hole. I’ll have to tomorrow!
@@bwines16 "Fixing" Voyager 1 to some degree is probably one of the most astonishing achievements in space flight in recent years, given the circumstances.
Hollywood treats space like they treat based-upon-book films; discard the stuff they think is boring, and add some drama to bits they want to keep.
Stars don't go nova when they're born, they go nova when they are old and dying.
A tree falling in a forest with no one around to hear it *does* make a sound. The sound is the vibration of the molecules, not the act of hitting a sensory device like an eardrum.
If you come into your house with the phone already ringing, for example, it didn't start making the sound when you entered.
Gimme back my thunder! I was about to say the same thing.
Somebody is far too literal and doesn’t understand a paradox
The point is not wether or not the tree would make a sound, but wether or not this could ever be 100% proven. Which it couldn’t.
@@Bianchiboy The question is *literally* whether it makes a sound, and that's how Simon tackled it.
Also, other animals exist and even insects hear, so to say a sound doesn't exist when no one is around is going to be extremely rare.
@@FrankCoffman words mean things, don't alter that meaning willynilly.
sound
/saʊnd/
noun
1.
vibrations that travel through the air or another medium and can be heard when they reach a person's or animal's ear.
If a tree fell in the forest, it does produce sound because it does make sound regardless if someone is their to hear it. Physics demands it.
There. But I agree.
I mean it produces sound waves. But they only become sound when they hit something capable of experiencing sound.
@@rickwrites2612every single thing that contains mass in any capacity experiences sound. The other trees experience sound, rocks, grass, the air around the tree, etc. If you're saying that sound is just an interpretation of sound waves, then sure I guess? But that's such an overly specific way of trying to disprove this "myth" and if you go around with this thought and tell people "oh, nobody heard it, so therefore it did not make noise!" well then that's a propagation of misinformation in my eyes. It made sound. The tree displaced atmospheric molecules, which produced sound waves that echoed throughout the nearby area. Just because center of the universe Jimmy didn't hear it, doesn't mean it didn't exist at all.
Vibrational resonance in the molecules of atmosphere and surroundings yes. Sound requires something to perceive it. It comes down to definitions of the words.
Unless of course, no one is around to hear it which means the answer is no
One of my favorites is how hollywoods portrays storms on mars, blowing around people and heavy equipment. It seems EVERY movie about mars has at least one storm to set up the drama. While a 70 mph wind on mars would affect you as much as a light breeze on earth.
That's an excellent point! I'm currently re-reading the Mars trilogy by Kim Stanley Robinson and by the the series terraforming of Mars reaching it's later stages, humanity has thickened Mars' atmosphere such that its winds actually DO become quite impactful!
It reminds me a little of the Parker Solar Probe passing through the outer atmosphere of our sun. You can have temperatures of many thousands of degrees in this region (apparently) and yet as long as the craft's trajectory is careful and the heat shield always faces the star; the craft is okay - and part of the reason for that is that while the temperature is very high, the density of particles or plasma(?) in that region is sufficiently low that it the craft is able to survive limited periods within it.
With number 1 I immediately recall the first time I saw Akira when it was released on VHS. I thought the movie (still do) was impressive in how realistic they tried to make the characters and objects move instead of the standard Cartoon/Anime manner, but what impressed me the most was when Tetsuo goes into outer space and the second he exits Earth atmosphere all sounds are gone. That attention to detail, especially for an animated movie back then, was unreal.
You've got more chance of randomly finding another vessel in the Pacific Ocean than you have of even seeing an asteroid in the Asteroid Belt, or of randomly bumping into a satellite orbiting the Earth.
Given how often satellites have to do object avoidance manoeuvres, I would reconsider the last part of you statement.
Also depends on how you define "satellite". Do you mean a machine that operates in space? Or do you mean the more conventional definition of one object that orbits another due to gravitational interactions?
@@blackoak4978 I was thinking the same thing. Hitting a sat is a low probability, but WAY higher than hitting an asteroid. A lot of the maneuvering or satellites is because we keep many of them in relatively the same orbit. (and we've been dropping a lot of junk in space for decades.)
what you, including simon (well he just reads, doesn´t think to much) ignore is, that space vessels of any sort, especially spaceships in science fiction, travel with speeds that sometimes are multiple time the speed of light. At this speeds the distances between the asteroids gets travelled so fast any form of avoidance is impossible, from reaction time to just plain inertia. Average distance in the belt of our system is said to be travelled by light in 3 seconds ... but how to you see a asteroid 1million km away? So whenl you see it, it is to late...
@@gshaindrich And you're missing both the "sci-fi" of such tech, and _the entire point._ If you can travel faster than light (or even a fraction), you have shields, deflectors, and sensors that can see more than 3ft in front of you. Our belt is not so dense light cannot get through it; in fact, most straight lines through it doesn't hit anything. (none of our probes have had to do any corrections to avoid hitting anything. we've made course corrections to actually reach asteroids.) Gravity would coalesce any field as dense as Hollywood paints.
Passengers is a good example. A ship moving at half the speed of light (roughly), with pretty beefy shields. The field it went through was somewhat realistic, with a good bit of distance between rocks, and not that many hitting the ship. (of course, that ship had some pretty lame programming unable to analyze or accept the unexpected. Just putting things in orbit, we've learned there's no such thing as "that can't happen".)
@@gshaindrichyou think soanxe is WAY more .... not soace... then it is. When the Milky Aqt and Andromeda collide: no starts will. That's how empty 2 galaxies coming together ok space is NOT dense.
Cold fusion is the least of ST: Into Darkness's problems
The entire Kelvinverse is a giant stack of problems.
@@JarrodFrates It's a "wouldn't it be cool if.." kind of thing rather than any attempt at realism.
@@JarrodFrates Agreed.. It's Star Trek for Dummies
yeah, really had to leave all my science and physics at the door to enjoy that one
When I hear sound effects in sci-fi movies, I always interpret the sound we hear in the cinema as a representation of what a person dying in that explosion is experiencing. One of the best representations of an actual space explosion was in The Last Jedi when it went totally silent for a few seconds. It was dramatic, it was effective, and somewhat realistic given that sound doesn't travel in a vacuum.
I like to think that when we hear the sounds of a spaceship in film, that we are hearing approximately what the ship's passengers hear. This doesn't really transfer to objects like missiles etc. I do respect when Firefly, 2001, 2010, etc. respect the silence of space, but I give a pass when they don't because of dramatic license. It's a small transgression IMO.
The Total Recall scene was not in space, it was in the Mars atmosphere. Mars' atmosphere is composed of 95.32% carbon dioxide, 2.7% nitrogen, 1.6% argon and 0.13% oxygen. The atmospheric pressure at the surface is 6.35 mbar which is over 100 times less than Earth's. Making it even less scientifically accurate, but I thought I'd make that distinction.
I would question the conclusion concerning your body's ability to adapt to one atmosphere (Atm) of pressure change. As a scuba diver and a former US Navy Aerospace Physiology Technician, I admit that a single Atm is reasonably easily handled when moving above 1 Atm, but when going in the opposite direction the relationship between temperature, pressure, volume and boiling points of liquids. There is a very good reason pilots who fly at extreme altitudes are required to wear pressure suits. Although it is cold enough to freeze very quickly at approximately 63,000 ft in altitude, the air pressure at that altitude brings the boiling point of the blood to around standard body temperature. In space, depending on your protective gear etc it would just be a race between what kills you first, but I believe the embolism, possibly secondary to your blood gasses coming out of solution (boiling) would win.
True. Even a dog is smart enough to be terrified of a vacuum......
So... turns out, 2001: A Space Odyessey is the most accurate representation of space exposure in a movie... Good job Kubrick!
Fun fact: Frank Poole survived! Sorta.
His body froze fast enough that when a comet miner stumbled on it 1,000 years later, he was able to be revived.
The Expanse is also pretty spot on.
The Expanse is defin6the most accurate depiction of living, working, traveling, and fighting in space. Highly reccomend.
Well, he had Arthur C Clarke sitting next to him going, "no, that's not right!"
@ripn929707
I hate that show. It's typical Hollywood softcore porn with the edgyiness dialed up to 2000 on a dial with only 10.
I will say they do kinda have the vastness of space feel dialed in pretty good. Things like startek make it feel like your ship is 10k miles wide and everything is just 5ft over there. A solar system is about as cozy as my living room according to them. So I get where your coming from cinematicly. But the entire series is boring and predictable and almost entirely forgettable.
A note on space explosions:
I usually have a little chuckle when a post battle debris-field is shown, with lots of big and little pieces of a ship drifting around.
The micro-gravity of the ship's mass is not sufficient to keep the bits and pieces from falling away in whatever direction the explosions would have blown them.
They would be travelling away from the the ship's original trajectory, at a wide range of velocities, depending on mass.
So the debris-field would rapidly expand without constraint.
There's no reason to think any 2 pieces would stay close together, let alone thousands of them.
Yah ship vanished boy.
True, but that would not look cool on screen. That is the point of suspending disbelief when watching sci-f movies. Otherwise, they are ALL incredibly stupid.
I've always chuckled at when a spaceship is hit and it starts to fall downwards on screen as though it's sinking, what??!, there's no gravity pull to initiate a downward trajectory.
Funnily enough when movies depict a big explosion on earth the parts get blown in every direction and away from the point of explosion which is true. But in space with no gravity or atmosphere all the parts just hang around together.
If the sound from roaring engines is heard within the ship, but not when the camera pans outside of the ship, that would be an accurate depiction of how sound would work in and out of a space ship.
NASA has Voyager 1 back in communication!! They were able to send a patch and are currently running tests. but they do have understandable information once again from the probe
Oh that's great news! Thanks!
Yay, NASA!
The IT Help Desk at NASA is a helluva thing, isn't it? They were able to send a fix for a computer 15 billion miles away that was built before home computers were a thing. And it worked.
NASA are the real rock stars.
@@scottwooledge6387 You could say the asteroid belt are the real rock stars oh that was bad

If you're going to pull up the narrator on accuracy, do make sure your grammar is correct.
... Know why I didn't pick up on that? Because he probably did it on purpose so a bunch of people commented.
And yet here I am, pointing that out anyway.
@@curiousuranus810 not everyone’s first language is English… but everyone knows basic science and spreading misinformation to the younger generations could be detrimental to their future, so why not point it out for everyone’s benefit?
Always thought it was interesting how fatal Hollywood depicted not having a space suit, meanwhile Gundam seemed to figure that you could survive briefly just fine.
Again a slight _Um, Actually_ for Chapter Two: Detonation simply means that the speed the reaction (sometimes combustion, sometimes decomposition) propagates through a material is faster than the speed of sound in the material. It's not instantaneous, as shown by numerous instances of _very_ high-speed footage (shoutout to the Slow Mo Guys), but it can be _very_ fast. Black Powder can also burn in a total vacuum if the container it is in relatively small and the ignition source creates enough pressure for the reaction to take place (See CodysLab doing exactly this).
Thanks for pointing out that "instantly freezing when exposed to the vacuum of space" idiocy. It has been driving me up the walls in every SciFi Space movie I have ever seen, which has portrayed it like that.
- NASA has actually just recently managed to bring Voyager 1 back online, with some very clever reprogramming and work arounds, avoiding using the damaged systems. Really rather impressive considering the age of the tech and the probe itself.
- While the asteroid scene in "Star Wars: The Empire Strikes Back" is questionable at best, since we aren't provided with any information about whether these asteroids are in a belt formation round a star (like ours) or in closer proximity to some other form of gravity well. The same cannot be said about the very similar scene in "Star Wars: Attack of the Clones" with Obi Wan, Jango, and Boba Fett. Simply because, as we can clearly see in the beginning of the scene, it takes place inside the ring-system of the planet of Geonosis, where these "asteroids" very likely would be much closer together due to them orbiting the planet.
- And finally; Remember that in space no-one can hear your black hole rumble (a LIGO/Alien related mash-up joke).
15 or 20 years ago I got the original Star Wars film and started to watch it as I had been told all my life how great it was. Could not hang more than about 10 minutes as the acting was so horrible and the story ridiculous. So now I just block anyone who starts rambling about Star Wars as I naturally assume their brains are switched off.
Not to well actually but lol. In Ep IV, Han says an asteroid field, iirc, and it's not anywhere in a system. So my conclusion always was it was just something completely uncharted and just randomly in interstellar space, remnants from some random collision of some sort perhaps.
@@paulmartin2348 I totally get what you are saying, but their brains being switched off, that's a bit harsh. A Star Wars geek's response to that would probably be something like "only the Sith deal in absolutes." 😆
It is a different imaginary state of mind, that's for sure. One which allows for just enough leeway for us to enjoy the story. The amount of leeway needed obviously heavily varying from movie to movie and person to person, and a person's individual relationship with science. Because it is a detachment (or escape) from reality. And you know; we all do it. Because without putting ourselves into a different mindset, we wouldn't really be able to enjoy any kind of movies, TV series, computer games, or even just a book for that matter.
The problem I have with this "instant popsicle" idiocy, is that when movie-makers just keep repeating the same mistake and reinforcing this nonsense, it ends up annoying me enough to pull me out of my imaginary mindset, presumably just like all the nonsense in "A New Hope" does to you.
Most SciFi movies from that era are more like really drawn-out low-budget psychological thrillers. I mean even "2001: A Space Odyssey", although not so low-budget, it still mostly falls into the psychological thriller category... And then along comes George Lucas with this "A long time ago in a galaxy far, far away..." fairytale adventure movie, which just happens to take place in space. It broke all the previous constrains of what a SciFi movie could be, and that's really why it became such a huge phenomenon.
So, that's really were you need to send your mind mentally; into the same place as when watching The Lord of The Rings, Harry Potter, etc... or actually even The Matrix... OMG, that one hasn't aged well either: telephone booths, cutting landlines, "the mind can't survive without the body" BS, going against the core concept of the very manga movie it was trying to imitate. Don't get me wrong, I love The Matrix. But I still have to detach myself from reality and commit to its fantasy world in order to enjoy it.
The asteroid field scene, like many other scenes in "The Empire Strikes Back", is pretty ridiculous by todays standards. But if "you're" going to nitpick and say "the asteroids are never that close together in our asteroid belt" then you expose that you're unaware of how much you are assuming about the situation and which you actually don't know. Simply because George Lucas didn't bother with presenting you with all the details... Again, because it's a fairytale adventure movie and not a science documentary. 🥸😆 (But also because George didn't know... or care.)
@@fett713akamandodragon5 Yeah, and if the imperial pilots are anything like the stormtroopers, then for all we know it could just be debris from their latest attempt at parallel parking. 😆
@@Zhixalom lol, true enough!
That's why I love The Expanse❤
No doubt! Naomi's jump without a suit from one ship to the other. Pretty dang accurate, along with so many other scenes in the series. Quality science fiction.
Truth!
Unless you are really close to a star, the greatest (only) form of heat a person would feel is their own: we are highly exothermic and, without other factors killing us sooner, dissipating that heat would fairly quickly become a serious problem.
No they don't. The sounds you "hear" in space in movies, are easily explained away as what the people *inside* the ships hear. In other words, most of the tech used is still making sound *inside;* where most of the tech is, and where the ship is filled with air; so most of what you're hearing is what the crew inside the ships are hearing. And then there's the fact that a lot of space movie scenes take place in high orbit, where there is still small amounts of air; and thus still sound. Albeit muted sound, but sound none the less.
And another thing! Why are all spacesuit helmets/visors illuminated from the inside? The light shining in the astronauts face would make it impossible to see!
Because they pay a lot for beautiful actors. They are not hiding all those dollars behind some dark visors.
Blame The Abyss.
Voyagers: the dish facing forward is a common mistake in animations. They communicate with Earth. Backward. Oh my.
In the Flash Gordon serials, not only was there Oxygen but even Clouds in Space.
So in 2001 Space Odyssey when Dave the astronaut is locked out of the spaceship by HAL, and he has to jump through the air lock without his space helmet, that is technically feasible.
Voyager 1 is sending telemetry once again.
Really?? 😮 I'm so happy to hear that!!!!
@@SetiSupremethis video must have been recorded ages ago 😂😂
Stubborn little craft
It was fixed a few days ago. Dodgy memory in one of the computers. Nasa sent a patch up telling the spacecraft not to use that bit of memory and since then they've been receiving good data again.
@@deadzio That must be it 😀 or he just hasn't come across the latest on the Voyagers. I too had missed it even though I spend some time on nasa.gov
I do like the Idea of asteroids being dangerous in space as an unstable place to be upon or hosting the eggs of some space-faring biological creature which is neat.
I think the reason Hollywood depicts "Freezing in Space" is because Space being cold as cold is the absence of heat it's easier to show people freezing to get that across than just letting people pass out and suffocate as it's more dramatic.
Yep. I think drama trumps accuracy every time.
up in space , or down in the ocean, it's asphyxiation. funny thing about the life zone
@@donaldwert7137 I mean, you could also have people catch fire and explode when they can't swim, that would be dramatic, but that isn't what happens. Space is a real thing, and when you go there, you don't instantly freeze.
@@HuckleberryHim Of course not. Even the depictions of drowning are dramatized, usually with plenty of thrashing in the water, etc., when in reality most drowning victims go under and stay under, no cries for help, etc. I drowned when I was a kid and would have died had my brother not spotted me at the bottom of the pool, pulled me out and applied what was then called artificial resuscitation. This was in a motel pool with plenty of people around and no one saw it happened, the first clue there was anything wrong was that no one had seen me for a while. That's how real life works and people have a general, if inaccurate, idea of how drowning works. In a movie, the event would have looked very different in order to engage the viewer. Very few people have seen an explosion in a vacuum, so great liberties are taken for dramatic effect.
Did not appreciate how Guardians of the Galaxy represented it twice.
There's a special place in hell for the people responsible for the cancellation of The Expanse..
Honestly, they did the right thing, unlike game of thrones. The showrunners said they stopped because they want to wait until more books are written I believe.
@@fett713akamandodragon5 actually the book finished during the final season of the show. They already had three book materials to work with.
The reason it got cancelled was the contract is over and the show is on hiatus because the Laconian Arc has a 30 year time gap and the feasibility of production is not realistic and still needs more time. Also they need to find a show runner to help with the production cost.
Is it next to the place where people talk loudly in movie theatres?
@@fett713akamandodragon5All of the Expanse novels are finished. The last novel released before the season 6 premiered.
@@fett713akamandodragon5 I heard one of the biggest reasons was because they had to kill off the Alex character (didn't happen in the book series) just because the actor was such an unbelievable asshole to work with, they had to just finally fire him. And because of that the whole storyline just got thrown out of whack. They don't have any plans of reviving the show.
It always dives me nuts when films depict astronauts instantly freezing solid in a vacuum. It takes time for the chemically produced heat in a body to cool in a vacuum. Some energy transfers need other matter to cause an accelerated state change. When people contest this, I usually just ask them if they like tea or coffee. Vacuum mugs are a fantastic real world example of this effect.
7:00 There was a Russian who was testing space suit designs when he tested one that didn't work so well.
He survived and made a full recovery. He described the sensation of the saliva in his mouth as very strange and quite cold.
Water boils when it contains more heat than it can hold onto. Boiling is the process that water uses to shed this extra heat. So in a vacuum water will boil until it is cooled below the freezing point and becomes a solid. No matter how warm the surroundings are.
I saw that footage! He was in a vacuum while wearing a space suit, and he felt the saliva in his mouth boiling. Then he fell onto his back.
The phase of matter that water is in depends on temp and pressure. In a zero pressure environment liquid water once exposed instantly boils to a gas. The phase change will result in heat being drawn away and some of the water becoming a solid (ice) eventually tho it will become a gas. If the water is frozen it will sublimate directly to a gas but will do so a rate that is slower the lower the temp. Phase changes always occur with conduction of heat.
@@undertow2142 wouldn't the blood in the body also be boiling?
@@exoticspeedefy7916 Not if the pressure of your body containing it remains relatively normal. Depends how strong/elastic your blood vessels/skin/muscles are.
Pressure suits are absolutely not necessary for space. We do not turn into a casserole on exposure to a vacuum, unless the exposure is close to instantaneous in which case injuries will be minor. NASA are spending billions on new space suits, designed to contain their wearers in a semi-inflated balloon which greatly limits movement, even causes injury (to the hands in particular, as reported by many ISS astronauts). All that's needed is a respirator of the re-breathing type, and face mask. Excess heat is a major problem in space, as any satellite engineer will tell you. So a cooling suit is what is required for longer EVAs, but shorter excursions require nothing more than protective clothing, against micro-meteorites and / or regolith. This all seems quite straightforward to prove, and has been if our hapless cosmonaut is anything to go by. Maybe space engineers don't want to be shown to be chumps, that they could have been performing EVAs using basic diving gear all along.
Sound is a vibration that propagates as an acoustic wave through a transmission medium such as a gas, liquid or solid. An ear doesn't need to be there to hear it for the wave to exist. Who wrote this?
Sound waves are vibrations propagated etc. Sound is an experience derived from them.
@@keithposter5543 sound is vibration whether something is there to experience it or not. Literally by definition.
@@keithposter5543 I just rechecked myself. Oxford English, MW, wiki, none define sound as having to be heard. You're describing the definition of the word "hearing".
@@TheHonestPeanut Ok, IMHO they're taking a shortcut and effectively defining for 'common usage'. BUT, this all comes from the original philosophical question: "If a tree falls in a forest and no one is there, does is make a sound?" Let's assume that there are also no animals with hearing there etc, then the answer is "No, it does not make a sound". You could say it makes 'sound' if we accept that sound waves = sound, but it does not make *a sound* .
You could also argue that it's impossible to say if it makes sound(waves) with nothing there to detect them as there will be no evidence after the fact 😉
@@keithposter5543 You're describing hearing. Stop being wrong. It's boring.
Love the shoutout for The Expanse, what an excellent show
The fusion error is the main one but not the only one. The Total Recall scene was on Mars, so not in a vacuum, only at lower pressure. It works to get a feel for radiation energy from the sun or heat loss to space by standing outside on a clear day or night. The atmosphere filters that a little but not much.
When I head about the Walker Solar Probe "touching" the sun it made me think of an old song. Quoting the song I said, "I had a friend, they say he got crazy once and tried to touch the sun. He lost a friend,, but kept the memory. Now he walks in quiet solitude because in space, no one can hear you scream."
John Denver
Animals have eardrums, and even in "empty forests" birds and outta the select few insects that have ears and can perceive sound most of those species live in the forest. Therefore if a tree falls in the forest, it always makes a sound because the odds of not a single pair of ears is within earshot of that is a number I don't think we even have a name for...
the question is phrased with "...and no one is around to hear it."
so yeah.. that would include any animals or insects that would be able to hear it
(i still am certain that the sound waves would be created, which would be the sound of a falling tree, but the question is rather specific in that regard)
@@Yourehistronic but you will never have a forest where NOTHING lives.... there will always be at least insects... Thats why included an "empty forest" which is a forest where no mammals live....Its like Schroedingers Cat. The cat itself is a conscious observer...
Its because we know more about biology now than we did when these 2 thought experiments were first conceived and now they are outdated... Yes I get the theoretical and hypothetical in nature of both and aren't supposed to be physically carried out, but that ruins the whole validity of the experiment... Here's a newer thought experiment that makes sense because of our better understanding of light...
"If you could travel faster than light, your perspective would be completely shrouded in darkness and completely invisible to everyone else.."
See how that is not only way more difficult to debate but impossible to debunk..?
@@Yourehistronicit's overly specific and relies on some annoying, trivial thought process to support it. The tree falling displaced atmospheric molecules in the space it fell through and again by colliding with the ground. This generated sound waves. It's overly specific to say that just because the sound waves weren't interpreted by some sort of sound translating structure, that all of the sudden the sound just didn't occur at all. It's stupid. The tree itself propagates, absorbs, and deflects sound. The ground it hits absorbs and deflects sound. Everything in the area that the sound waves reach are affected by the sound wave to some degree. Our eardrums also absorb sound. There's no reason to say that just because something didn't hear it, then the sound didn't occur at all.
Imagine I am wearing 100% soundproofing earphones and I honk my car horn. Did the horn make a sound? Well, bar my horn being broken, yes it definitely did make a sound. This argument that the fell tree doesn't make a sound is factually flawed. Sound will always occur as long as there is any level of molecular movement occurring. Even at an atomic level, sound exists. It is just far too faint for us to hear it. Everything makes sound all the time. And sound is constantly scattering and deflecting and diminishing everywhere all of the time. Sound conflicts with itself and other sounds, conflicts with other masses of all matter states.
So to answer this horribly misled riddle of "if a tree fell and no one was there to hear it, did it make a sound?" Yes... it did. It made sound before it fell too. It made sound after it had already fallen as well. It will also always make sound as long as there is a tree at all. Stupid, stupid riddle.
@@Yourehistronic
In what version of the English language would "no one" in that context include animals?
@@Jayson_Tatum It depends of the definition of sound. One definition is: "the sensation perceived by the sense of hearing".
By that definition it is true that there is no sound if not heard.
I agree it is a silly definition and of cause a falling tree makes sound waves in it's surrounding materials (air etc.).
That is my opinion.
I remember reading a Sci-Fi short story a long time ago, that was written by one of the classic Sci-Fi authors in the 1950s, although I can't remember which one. It featured a rescue of some passengers on a space ship that had suffered some kind of accident and needed to be evacuated quickly, but there were no space suits for the passengers to wear while moving over to the rescue ship. The distance between the two ships was short and could be traversed in less than 2 minutes by pulling one's self along a tether between the two ships, so they had the passengers enter the airlock of the doomed ship one by one, hyper-ventilate to maximally oxygenate their blood and then expel as much air as possible from their lungs before holding their breath on the exhale, so that there was little to no pressure from air in their lungs. Then they opened the airlock and had the rescuing astronaut (iirc) drag them to the rescue ship by pulling himself and the passenger along the tether. This blew my mind at the time, but tracks with all the information in this video. Those old Sci-Fi authors sure knew their science.
I'm really glad he mentioned The Expanse. It's one of the best sci-fi show out there and certainly the most realistic.
before he gets to it, I wanna say.
Sound can be captured by light, foregoing a medium.
See Veritasium chip bag sound
Ayup. There's also all the sound engineers who work with sound converted to electricity.
the medium is the laser
the laser oscillates and is picked up by a receiver which translates the oscillations into sound waves(speakers)
@@eekee6034 electricity is the medium, in this case

That movie was interesting.
I think you can hear an explosion in space, if you're close enough to it. A chemical explosion works by creating a mass of hot, rapidly expanding gas. If some of that gas impacts your space helmet, that could send a sonic vibration through the wall of the helmet, which could then couple to the air inside your helmet, for you to hear as sound.
I've been telling my kids this for years:
"It's a movie; it's not supposed to be taken seriously. If it was meant to be taken seriously, it would be a documentary."
The sound thing was pretty fun in high school physics. Teacher made a vacuum and put a noise maker in it and poof gone, that’s where the story should end, instead he asked if anyone had any comment to which I raised my hand …
I said in front of an entire class and the teacher “Why hasn’t anyone tried this with babies?” Six of us found it hilarious, my friends of course, the principal and guidance counselor not so much….. to be fair it was a college prep class so I figured we were mature enough for dark humor
I mean, it would work if you gave the baby an oxygen mask...
🤣
The Expanse getting some love!
Nice Expanse callout. I LOVE the sequence when Uncle Mateo just opens his helmet on an asteroid to fix a junky wire. Real as you get.
My explanation for space sounds is that in the future, all ships will be equipped with audio awareness systems, so people can still use their ears to tall what's going on around them without having to look at screens. Devices on the exterior of the ships will sense engines, movement. light, etc. and turn that data into sounds played inside the cockpit over many speakers. If you have a missile approaching from the upper rear left, you''ll hear a simulated missile sound from that direction.
Let's not forget if your spacecraft gets the tiniest of holes expect to be slurped through it like spaghetti from the decompression.
Kind of like the people that were sucked out of that air Alaska flight?
@@patcusack6252it’s different for planes because planes are moving very fast through an atmosphere. Spaceships aren’t moving in an atmosphere.
@@patcusack6252 If someone was sitting in the closest seat, they likely would have been ejected. Just look at the condition of the seat. It was stripped down to the metal frame.
But that was from the slipstream, not the decompression itself.
@@patcusack6252 NO because because being sucked out of a tiny hole isn't a thing. Being sucked out of a much larger hole is.
No the pressure is only 14psi, a small hole would not suck you out, there is only so much air that can get through a pinhole at that pressure. A large quickly appearing hole on the other hand is a different story. More square inches more total push on the surface, and faster evacuation. And come to think about it, our space craft are only at like 8 psi not the normal 14: so even less.
Every tree ever makes noise when it falls, whether anyone is around to hear said sound, is another matter altogether.
Does it have to be a person hearing the sound? How about a deer? A bird. An insect? A bacterium? A plant?
It depends on the question. If there's no*thing* to hear it, it doesn't make a sound. Period. If there's no*body* to hear it, it likely makes a sound as birds/other animals with hearing could hear it if they are there. As long as there's an atmosphere, it will make sound*waves*, but not necessarily sound, as that is an experience, not a thing.
@@keithposter5543 By definition, in a forest there would be at least other trees and/or plants that could "hear" the tree fall. There likely would be other living organisms as well.
@@KnightRanger38 Trees/plants don't have hearing
@@keithposter5543 Sound is a thing, its energy being propagated through a medium and id doesn't matter if anyone is there or not that transfer of energy still occurs
One of my favorite imaginary space things in movies (or, mostly, Star Trek) is that being inside a nebula is like being surrounded by multi-colored clouds.
On topic in chapter 3 (freezing/exploding in space), The Expanse did a pretty good job in enacting such a scenario. At first, it looked like more fiction than science until explanations like yours started to make more sense. In general its an absolutely amazing TV series with overall good science accuracy and on spot physics.
Everyone should go watch The Expanse if you want to watch closer to reality space stuff
Absolutely love The Expanse! One of the best sci-fi series ever.
I totally agree!!! Best Science Fiction Television Series of the 21st Century!
Has its minor faults (which were owned by the producers). And before someone points out the engine and thruster sounds, they´re just a concession to make space shots less dull and more engaging. Although personally i would´ve been totally fine with dead silent scenes, i bet the majority of viewers wouldn´t have liked it a bit.
I love how closely it pays attention to the science of space. I remember wondering why the ships were flying backwards before i found out they turn around and slow their momentum at the halfway mark and that's why the ships have partial gravity. Just wild 😊
I agree. I was very pleasantly surprised with how that show tried to keep space accurate but also very entertaining
Fun fact shrapnel only exists when it comes from a WW1 Shrapnel shell created by Henry Shrapnel. This is actually fragmentation.
Thanks for setting that straight. Keep up the great videos Simon.
"If a tree falls in the woods, and no one is around to hear it, that tree doesn't make a sound.' is gibberish. It still makes a sound, as there are adjacent molecules to transfer said vibrations. The laws of physics don't just stop to work, just because you're not around.
Even if there are no ears within the area of a falling tree, it still makes a sound. Just as a star continues to burn brightly even if there are no eyes to behold it. Several people here have already stated the (presumed accidental) reversion regarding hydrogen comes from helium so I will leave that one out.
It makes sound waves, not 'a sound'. Sound is an experience interpreted from sound waves, not a thing itself. (edited for harshness)
@@keithposter5543 Which is all the falling tree ever makes regardless of ears nearby. The falling tree never interprets the sound waves it creates so it makes what it makes in all cases.
@@craigthomas2497 OK, looks like I've opened a Pandora's box of semantics. 'Sound' seems to be commonly defined as 'sound waves' - but the original philosophical question referred to in the video asks whether the falling tree makes "a sound" if no one is there to hear it. Discounting birds/animals (let's say that "no one" means "nothing"), the tree does not make "a sound" because "a sound" is an experience
By this logic, light isn’t a thing either, it’s just light waves. So I guess all the stars in the early universe were just wasting their time shining since there were no eyes to see them 😂
@@user-om7yl4dz8h Ha - well, you're getting deeper with that one. Light is electromagnetic and perpetual, sound waves are just movement of objects and dissipate quickly. We can still see stars from the early universe and light might be a particle or wave depending on who's looking 😉

For those looking for more intormation about actual solar fusion...
Two protons (basically Hydrogen plasma) fuse into Deuterium, a heavier isotope of Hydrogen
A third proton then fuses with a deuterium atom to form Helium-3
Two Heilum-3 atoms fuse to product (eventually) Helium-4 and a lot of energy
After that, older stars will start fusing Helium into Oxygen, Oxygen into Nitrogen, then Nitrogen into Iron.
Sadly, at that point, fusing iron into anything heavier requires an input of energy instead of generating energy, so the star stops generating energy and collapses.
There are more branches after formation of deuterium. For instance two deuterium nuclei can form helium-4 directly
I love how Gravity(2013) didn't make your list. As much as I love space films and science, I couldn't watch that film for the one inexcusable Hollywood element they showed in the trailer that was no doubt wildly annoying throughout the whole film: an astronaut constantly panicking and breathing heavily.
Astronauts go through rigorous training to get rid of the panic response and know that hyperventilation and lack of oxygen can lead to their death by using up all their oxygen or passing out and being unable to do anything. No astronaut with this temperament would ever make it through the training, let alone into space.
Nonsense. Hyperventilation only consumes your oxygen supply if you're using an open loop supply. That would be incredibly wasteful. Spacecraft and spacesuits use carbon scrubbers, and operate more closely to rebreathers than standard SCBA gear.
But wasn't Sandra Bullock's character a scientist? Yes, they have training but they're not freaking robots.
All humans have some degree of panic response, even highly trained soldiers.
remember being around 6 or 7 when i first saw Akira and running over to my dad to show him the space explosions with no sound thinking how cool it was : p
At 8:27 - You made a mistake - what you want to say is that Hydrogen isotopes fuses to produce Helium, plus byproducts.
Someone else might have mentioned this. Hydrogen fuses into helium not the other way around. You seem to have accidentally said it backwards.

No, sound can also just refer to the waves traveling through a medium (not just air) - so you don't need anyone around to hear a tree fall to call the waves sound. Sound is not only defined by brain-connected ears processing compression waves.
Detonation exceeds the speed of sound. Deflagration does not. 3:21

There is a Tv show (Firefly) without sound in space...It's strange so they play country music to fill the void which is stranger.
The expanse tv show is top notch also on physics in space (gravity, freeze...)
I love firefly!! And Serenity, except for that thing we pretend didn’t happen! Does this mean they were wrong about the freezing to death episode too?🤔
Why is country music strange in a show about the wild frontier? Firefly is a Western. Country music is mandatory.

Fine, but Kahn still has one of the very best lines in Hollywood history:
“Do you know the Klingon proverb which tells us revenge is a dish that is best served cold? It is very cold in spaaaaace.”
Plenty of ears in a forest.
My favourite space movie incongruity is when George Clooney stops floating away in Gravity when Sandra Bullock catches him, but then somehow continues to float away when she lets go of him. It's my understanding that he wouldn't continue to float away once his momentum is stopped. (Although, I'm no expert on the subject.)
I'm glad you out The Expanse on that list of things one should watch. Having watching rockets flip and burn to slow down was a nice touch from the get-go. Plus, there are plenty of other reasons.
I like how "by definition" rests on that concept in general.
Special props to the editor for using the light show to explain how sound waves work. That was fantastic editing. 😁
2 things. Hydrogen fuses into helium, not the other way around. And Voyager 1 started sending signals again after a 5-month break.
Also as an aspiring student wanting, and if all goes to plan, I must point out that stars work because of quantum tunneling, not just pure pressure or heat because they are not either.
Because sound doesn't travel in space, the Apollo 13 crew only heard a muffled bang inside their craft and only found out, how catastrophic the damage really was, when they abandoned the damage module, while returning to Earth.
