Don_DickleWe all grew up with In Space No One Can Hear You Scream...is this true? Is there any should out there without picking it up on an electronic device?
LumidaubI can almost parse this, if it weren’t for “should”. (Edit: ah, “sound” makes sense, duh)
There is no medium for sound waves to propagate in outer space. Hence, if you were able to expel air from your lungs in such a way that would produce a “scream” in our atmosphere, there’s nowhere for that scream to go so nobody could hear it. An electronic device needs that medium as well to receive the sound waves and transform them into electric signals.
Edit: but of course, if “in space” means “on a spaceship”, there’s a high likelihood of an atmosphere to transport the soundwaves through that ship.
Sound is caused by vibrations in a medium. Common mediums we experience sound in is air and water. You can hear how the difference in sound mediums affect how you perceive the sound.
Space has no medium for sound to travel it is a near perfect vacuum. There would be nothing to vibrate to produce sound.
… but if you’re in a medium in a vessel which is in space, then you’ll sure as shit hear someone scream.
Sure, just like right now, on spaceship earth!
EldritchThere’s a medium even in interstellar space. But the pressure is low, so transmission is as well. There is no hard boundary on ‘atmosphere’. Just smooth gradients of density across the universe
Technically true, there is matter in space. But the particles are so far apart that they don’t vibrate against each other, so no reasonable person would describe it as a medium of transmission.
Particle’s still collide in space. There’s nothing keeping them from doing that. Collisions simply increase due to increased pressure. It’s not really technical, just true. If anything it’s a misunderstanding to imply otherwise or that empty space exists. If you want to distinguish human audible. Then certainly it isn’t that. But then neither are infrasound or ultrasound.
Technically and extremely fascinating is that “space itself” not just the baryons inside it, is still a medium. Its literally how LIGO functions. And if that’s not mind blowing enough, there actually are massive structures in space caused by pressure waves that we can detect. Those are technical. And another fun fact, if the atmospheric pressure at sea level extended all the way to the sun. We would be able to perceive the sound of the sun. Millions of miles away. Everywhere across the surface of the earth a constant 100 Dba roar. A bit quieter than standing close to a jet engine.
LIGO Lab | Caltech | MIT
The Laser Interferometer Gravitational-Wave Observatory (LIGO) consists of two widely separated installations within the United States — one in Hanford Washington and the other in Livingston, Louisiana — operated in unison as a single observatory. LIGO is operated by the LIGO Laboratory, a consortium of the California Institute of Technology (Caltech) and the Massachusetts Institute of Technology (MIT). Funded by the National Science Foundation, LIGO is an international resource for both physics and astrophysics.
I’m surprised the sun would fall so neatly in our hearing range. Seems like the odds of it instantly shredding our eardrums, or being too faint to perceive were much higher.
Remember that dB is a logarithmic scale. Each 10 is 10x bigger than the 1 before. We talk at around 60dB, so 10,000x quieter. We can hear from around -9dB to 90dB (into hearing damage territory) that’s a 10,000,000,000x range. If you allow for hearing damage, a gunshot is around 140dB. So add 5 extra zeros to that.
Human hearing is insane.
Aha and you hearing people told us the sun wasn’t loud!
True. A sufficiently low-pitch sound will travel just fine. In neutral gas, it only breaks down as the wavelength reaches the mean free path of the particles.
On top of that, space is usually filled with ionised gas, and sound could travel electromagnetically. Actually calculating what that looks like in near-Earth space is beyond me.
RobotToasterDepending on your definition of scream, strong enough microwaves can be heard by an unaided human en.wikipedia.org/wiki/Microwave_auditory_effect
fallaciousBasisMicrowaves are electromagnetic radiation. And the effect (hearing) is produced in situ.
That’s not sound (a scream) which is a mechanical wave (relies on atoms and/or molecules to propagate.)
teftSpace has sound as sound is just waves in a medium. Space isn’t completely empty just really empty.
Here is a picture of sounds/sonic booms in space:
Wouldn’t there also be the question of what is sound? Aren’t there plenty of phenomena that allow us to “hear” something through space. Is it something like the medium is the message?
There are two components to a sound - the sound waves traveling through the air, and a mechanism to capture those waves, and translate it into sound. BOTH components are required for there to be a “Sound.”
In space, there is no air for the sound waves to travel. In addition, there would have to be an ear, or a microphone, or some other mechanism to capture the waves. Without either of them, there can be no sound.
🇰 🌀 🇱 🇦 🇳 🇦 🇰 🇮 There is no air in space, thus no medium for vibrations to propagate through; so yes, in space no one would hear you scream. You also wouldn’t be able to scream anyway since the vacuum would literally suck the air out of your lungs the moment you opened your mouth to scream. Not to mention all the other nasty shit that would happen upon being exposed to the vacuum.
As a true scientist I refuse to take your claims without proper evidence.
I require that you test this claim by releasing the richest 1000 Americans into space to assert your claims.
I will also accept the whole of the US Federal Government.
Can you do a kickstarter campaign to raise several billion dollars to build the rockets? Would it need to cost that much if there’s no cabin and we just tie them to a booster? 🤔
Which is actually surprisingly little! Just by random chance there’s no human body part that bursts in a vacuum. You inflate a bit and pass out due to partially boiled blood, but accidents have shown that if pressure is restored quickly a fit young person will get away with sore ears and nothing else.
