What is the speed of sound in vacuum?
Correct answer: Sound can not travel in vacuum

If sound cannot travel in a vacuum, why is my vacuum cleaner so damn loud?
Earth Janitor
That means the death star explosion should've been eerily silent
PTSD
that's why i can't hear my thoughts

Alien:BECAUSE YOU CANNOT SCREAM IN SPACE!
Shonkatron
Earth Janitor, Imagine all the space battle scenes in Star Wars being completely silent. Wouldn't have been such good viewing would it?
Guillermo
Greyghost 68, I need to buy my mother in law a vacuum

Thank you to the creator of this great game, not many games are not only educational, but are also a workout for your brain, really appreciated.

Mitrilys, Science astronomers say we pick up sound signals from far away stars and galaxies!
Maybe the sound carries through a vacuum, but is unable to be heard until it reaches a substantial medium for it to be heard!
brickmartian
no, it will travel through the beam!
kind of like the telegraph, or the older style telephone wire poles!
You spoke into a transmitter, carried through the wires, and heard on the receiver!

SpaceMan626, unless the sound was generated inside the cockpits which would have had to hold an oxygen like medium for the pilots!

I actually remembered that from highschool. I graduated in 1976
Tony
Greyghost 68, Ha ha ha. Because you're not in a vacuum, sweety.
SpaceMan626
Earth Janitor, and all the spaceships should not have gone "voom" when in space. lol
tessa j
Greyghost 68, Exactly!! I thought the question was the level of sound in a vacuum cleaner at first.
KW
Greyghost 68, just geekin out, but your home vacuum doesn't make noice from the negative pressure compartment :)
Puladancer
I think Dark Star and Silent Running were two of the few films to get it right
Lee
this may actually be proven to be wrong
ROCKET
Had me seriously thinking. I should've gone with my first instinct ie cannot travel in a vacuum lol

Shonkatron, silence in space worked in "2001: A Space Odyssey" because of the music. I'm sure John Williams could have handled it.
Wannabe Vulcan
Earth Janitor, thank you! Sound in outer space has always been a cinematic pet peeve of mine.

Greyghost 68, that’s why I don’t understand this question. I thought all sounds travel.
Purple dolphin
This question almost caught me out until I reread the question and saw sound and vacuum in the same sentence
Warda Fatima
Subhana ARMY💜, well same I will like it if you reply me
no
if you put a metal beam in a vacuum and connect it to a sound source, the sound will travel through the vacuum? 😬
Manpreet Kaur
it is so much fun to play this game. we can learn lot of things.
Mitrilys
Fun fact, since space is not a perfect vacuum, some sounds can still travel there. But regular humans can't hear them.
john
i like this app . a never ending learning
john
that is why some people appears so bright until they speak

Player #54731451, He was in his spacesuit where there was not a vaccum and a radio thing
Eduard

Fiona

Mouse
Player #54731451, he was talking in the radio station microphone, not in vacuum.
Mouse
TwoTin16, don't think it travels faster, just that we can hear better as less background noise, or silence.
Rick
