can lead to breakage....

 
So... once the barrier of sound is broken, are things so loud you can't hear them, or does sound simply cease to exist altogether?!
Hmmmm!

Hi,
 
There used to be a theory that sound could only be "heard" when there an atmosphere with some kind of "air" in it. A lot of this fell apart when the Pioneer spacecraft found the "aura" of Jupiter, and when it broke through it, there was a sound.  And that same spacecraft, also had recordings of sounds in space, which have been used by various musicians here and there.
 
Exist or not, is not for me. We spend too much time trying to say that something is or isn't, and not even appreciating it.

It's not a "theory". It's fact.
 
The "sound" recordings from NASA are not sound waves in the conventional sense, but are another completely different type of wave that just happen to fall in the same frequency range as human hearing.

But different from the waves people make at stadiums when they should be watching the game being played, ya? 

But, if a tree falls in the woods...
 
 
...on Jupiter?  

Here's a blip from http://www.physicscentral.com/experiment/askaphysicist/physics-answer.cfm?uid=20080512101814
 
"... at a certain point, something totally new happens. When the plane outruns its own sound waves, thus traveling faster than sound itself, its sound begins to pile up in a cone that radiates outward and backward from the supersonic plane. Outside the cone, you can't hear the plane at all. Inside the cone, you hear the plane as it was sometime in the past. But right at the cone, you hear a "sonic boom," a sudden surge in pressure as the piled-up sounds of the plane finally reach your ears. The cone moves along with the plane and as it sweeps over you, you hear the sonic boom.
 
The angle of the cone depends on how fast the supersonic plane is going but the fact that it sweeps along the ground means that not everyone hears it at once. Furthermore, the sonic boom has little to do with actually passing through the speed of sound. Sonic booms can be heard throughout the plane's supersonic flight and they're so disturbing to people and animals that supersonic fight is limited to unpopulated areas or oceans."

 
 
 
btw, When did they discover trees on Jupiter?

A good question for these guys:

I have always been fond of this bird. She basically did one thing. Go fast. Go very, very fast.
Growing up in the 60's I remember two things about military aircraft.
Sonic booms from F-100's flying out of Lowry AFB(Denver, CO) were fairly routine. If you saw them first, you knew the boom was coming. More often than not, you didn't, and by the time you heard it, they were gone.
My kids have never heard a sonic boom.
The second was B-52's. You could see the telltale 4 track contrail in the stratosphere. At the time, not much else could fly that high, so you knew what it was.

soens Sonic booms can be heard throughout the plane's supersonic flight and they're so disturbing to people and animals that supersonic fight is limited to unpopulated areas or oceans.

IOW, it's the aeronautical version of a bass solo.
