Had a thought watching 'Gravity' last night.

[Tilt]

Along with the thought of 'cor, she is still fit'............

 

In the words at the start of the film it states about space - at 600km above earth (iirc) that there is no sound. I think it stated 'nothing to carry sound'.

 

Why / how do NASA (or whoever it is) listen for outer space messages then, if space doesn't carry sound???

Intresting read

Well, their not listening for "sounds" its radiation sources the same as tv/radio signals but in a muuuuuch wider range of frequencies.

 

Our ears hear sounds via air being mechanically moved in a pattern. Sound waves travel through a medium as they are created, whereas Radio Frequencies are subatomic particles being (basically) excited (electrically, magnetically or heated up etc) to the point they break off and go flinging into eternity carrying their energy with them until they hit something.

 

Hope that helps a bit?

To quote Douglas Adams - " Space is big. You just won't believe how vastly, hugely, mind- bogglingly big it is. I mean, you may think it's a long way down the road to the chemist's, but that's just peanuts to space. "

 

Space carries sound just fine but it's really big so astronauts need to shout really hard to be heard.

Sound needs a physical medium to transmit the waves, the more dense the faster the speed of sound. Sound travels faster in water than air for instance.

Sound has no transmission medium in a vacuum.

 

Laughable movie. Maybe it was worth it in 3D or IMAX.

Starts off well and then gets more silly as the film progresses...  would look good on a IMAX I should imagine but then you would be going "wow look at the Earth"  rather that "What? That's improbable and silly."

In space, no one can hear you scream

The Martian was much better.
