/sci/ - Science & Math

How do you know there's no sound in space? Were you there with your ears to hear it?

No. You were here on earth pretending to be smart. Your father should have smacked you.

It's a common misconception, supported by Hollywood and "soft" sci-fi. Doesn't make it any less incorrect, but it's understandable that the general public would believe it.

Don't be a dick.

There is sound in space. Sounds are just vibrating frequencies, the only reason you hear them on Earth is because they're vibrating up against the air it's passing through; there is no air in space thus you can't hear sound, but it's still there as vibrating frequency that of which something like a radio can pick up and interpret.

OP here

damnit I know there is sound in space, bud the "sound" from the pulsars are radio signals damnit!

Radio signals are frequencies too, my boy. Please keep up.

If you don't know the difference between an EMF wave which is a plane wave and a sound wave which is a density wave then u don't need to be posting answers in /sci/. Radio waves are EMF, they are oscillations between electric and magnetic fields, thus they can move easily in a vacuum (ie. space). Sound is a density wave, transmitted by kinetic energy transferred between particles. Thus it requires a medium, thus there is no sound in space.

its just a really high frequency like a dog whistle, dumbass

That's mostly untrue, and contravening significance. If a wave is capable of being interpreted by any audio input and connotation, there would be no way to detect them.

I didn't know anyone this stupid existed on /sci/. Wow. Just wow.

>>1975910
If that were true we wouldn't have a way to detect them audibly. Maybe some other way, just not audibly.

>>1975935
Then you don't know science if you can't understand something as simple as what he posted.

...this thread embodies why I think at least half of the people that come to /sci/ are retarded.

There is no sound in space. Sound, by deinition is a compression wave and therefore must pass through a compressible media. Light [like radio waves] exists as a self propagating electromagnetic interaction that requires no media for it to be carried. Since space is a vacuum [only a single digits of hydrogen atoms in some number of cubic meters of volume], sound [a compression wave] cannot exist in it

i like how people on here would rather bring attention to a posters' intellectual levels instead of actually arguing the post itself and providing information for or against him

Oh, I fucking understand, alright.

That is not the definition of sound or audio.

See:
>http://www.google.com/search?&q=define:sound
>http://www.google.com/search?&q=define:audio

Sound and audio are frequencies that auditory input (ear, radio, speakers, etc.) can recognize and react to or with.

>>1975958
I don't really think you do since you haven't proven any understanding of the subject, neither evidence for it.

why so many of you fall into the trolls traps?

>implying that scientists don't send radio signals in space to speak with aliens, and that there isn't sound in space.

>>1976024
radio signals is light. sound doesn't have anything to do with radio signals. sound only moves through mediums, matter, in the form of a wave

Hey. Yo. Stupid people.

Radio waves = Light
Sound waves = Sound

You don't HEAR radio waves. You need a radio to convert them back to sound.

Nice, my ninja bro. At least someone here isn't retarded.

>>1975910
This person gave the best explanation.

i dont know whether its better if these idiots are actually trolls or if these trolls are actually idiots
