can a loud sound travel through the universe ?

Sound waves does not fall under Electromagnetic spectrum. Only electromagnetic waves (Eg:- Light, X-ray, Gamma Ray, radio waves, Infrared rays etc) travel through vacuum. \n\nSound waves require vibration in the air molecules. Since there is no atmosphere in the space, sound can't travel.

Not on any realistic scale.  The particles in matter move according th the net of all the forces acting on them, including gravity.  Sound is a disturbance to the position of those particles, which propagates as a compression wavefront.  Gravity affects the steady-state behavior of each particle.  Sound just creates a short-term displacement.

Yes!\n\nAs it turns out, radio waves are nothing more\nthan the propagation of electrical and magnetic\nfields through space--the E & M fields perform\nan intricate dance around each other and fly\nthrough space.  So yes, you can transmit\nenergy through the air and "catch it" with\na receiver antenna. That's exactly\nwhat a microwave oven does:  the business\nend of a microwave is a transmitter and antenna,\nand the food is the receiver.\n\nI suspect the energy needed to propel\na car-sized vehicle, however, would involve \ndangerous amounts of power.  Any bird, pet,\nor human which passed between transmitter and\nvehicle would be zapped.  Streets\nwould be littered with smoking corpses, and\nyou'd smell BBQ all day.\n\nBut hey, BBQ ain't a bad thing!

No, it doesn't damage the voice box...it has a different density, thus sound travels faster in helium

Sound travels at approximately 720 miles per hour. Light travels at 186,000 miles per second.

Sound travels in waves like light or heat does, but unlike them, sound travels by making molecules vibrate. So, in order for sound to travel, there has to be something with molecules for it to travel through. On Earth, sound travels to your ears by vibrating air molecules. In deep space, the large empty areas between stars and planets, there are no molecules to vibrate. There is no sound there.

If they were close enough to hear it.Yes...if not...no sound is made....sound consists of a transmitter (tree) and a receiver (ears) if one is missing then its not sound.\n\nGood Luck

Yeah, it will produce a compression wave in the air - which is the definition of sound.  It doesnt matter if someone is there to hear it or not.  A sound is still made.

Probably a similar thing to that which happens when you reach the sound barrier.  I'm sure the light particles/energy build up and will create an explosion.

Sound does not travel in space. \n\nSound is created when a vibrating object (your vocal cords, a guitar string, etc.) causes the air around it to vibrate. This vibration continues to expand outwards through the air (or water if you happen to be under water) until it reaches your ear drum, which in turn vibrates. Your brain interprets these vibrations as sound.\n\nSound does not travel in space because space is a vacuum. There is nothing to vibrate. So, when the vibrations (sound) reaches the upper levels of our atmosphere, it stops.\n\nSound does travel in the space shuttle because the space shuttle is pressurized and contains air that the astronauts breath. The air provides the medium to transfer the vibrations from the source object to the astronaut's ears.

Sound is actually just vibrations in atoms and molecules. Our ears are able to decipher these vibrations into sound, if the vibrations are strong and close enough. The laws of the earth are forever constant, so if a tree falls, whether someone is close enough or not, it will cause vibrations in the air and on ground nonetheless. Animals will hear it. There is no sound in space

The answer to this depends on if you are a physicist or a biologist! A physicist would say "yes" because to him/her sound is vibration of air molecules which will occur when a tree falls. \n\nA biologist, however would say "no" because sound is a perception in the brains of living things capable of perceiving it. The perception is a brain's interpretation of the nerve signals sent to it as a result of vibrations causing the eardrum to vibrate, then the ossicles in the middle ear, then the fluid in the cochlea, then the hair cells etc. There is no sound until a brain perceives it, only vibrating air.\n\nEven if the vibrations are recorded, there is still no sound until the recording is played and heard/interpreted by a capable brain.

It's the whispers from the big bang.

Yes, through wormhole and warp drive. A wormhole should be able to connect distant locations in the universe by bending spacetime, allowing travel between them that is faster than it would take light to make the journey through normal space. \n\nA warp drive would be a mechanism for warping space-time in such a way that an object could move faster than light.\n\nIf you would like to learn more about wormhole, follow this link http://en.wikipedia.org/wiki/Wormhole

Sound does not travel in a vacuum.

Universe is not exactly rotating or spinning... it is said to be constantly expanding... and sorry i don't know about the big band

They did this on mythbusters, episode 8.   I can't exactly remember why you can't hear it, but it does echo.  I think the echo came back so fast, you still heard it when you were hearing the origonal quack.
