Can Sound Waves Travel Through Space and Time?

In summary: James Townsend discovered the microwave-band radio in the 1940's. Microwave radiation is generated by sending energy into a medium at a very high frequency. This energy causes water molecules in a microwave oven to vibrate faster than the eye can see. This vibration creates waves in the water that can be seen as microwaves. These waves can travel through metal objects and hit your cell phone antenna.

I've been searching for a long time now, I hope some one knows something about it.
I heard that when u speak the sound waves do not vanish, they go into outerspace and stuck there, now scienets are trying to find a way to get the sound waves back and hear what old people siad (specially prophets)
is this right?
I need an artical about it with more info, anyone know where can find?
please please help
thx

I am not sure what you have been reading. You need to find better sources. The idea of a sound wave being stuck in outer space is preposterous.

Sound is propagated though a medium, such as a gas or a liquid or even a solid. It cannot propagate into or through a vacuum.

The energy which forms a propagating sound wave is dissipated in the atmosphere as the wave spreads, it soon reaches a point where it is indistinguishable from random thermal motion of the air, therefore is unrecoverable.

I am sure I read that some where, anyway now I have to search for a new topic, do u have any nice, easy topic to talk about... it must be related to scientific discoveries

You may have been read about radio waves instead of sound waves. Some frequencies of EM waves originating on Earth will propagate beyond the atmosphere and into space.
But since they don't turn around and head back to earth, listening to them from Earth is, as I understand, impossible.
One other point. Even if it were possible, the prophets did not use radio waves.

wrong

This is all wrong. Haven't you ever heard that sound waves can only travel through air! That why sound can't travel through space.

Microwave-band radio. How do you think they work?

FAQ: Can Sound Waves Travel Through Space and Time?

What are sound waves?

Sound waves are a type of mechanical wave that is created by vibrations in a medium, such as air or water. These vibrations cause the molecules in the medium to compress and expand, creating a wave that travels through the medium.

How do sound waves travel?

Sound waves travel through a medium by causing the molecules in that medium to vibrate. The molecules pass on this vibration to neighboring molecules, creating a chain reaction that allows the sound wave to travel.

What is the speed of sound?

The speed of sound varies depending on the medium it is traveling through. In dry air at room temperature, sound travels at approximately 343 meters per second (767 miles per hour). However, in water, sound travels at a much faster speed of about 1,500 meters per second (3,355 miles per hour).

How does sound intensity affect the loudness of a sound?

The intensity of a sound wave is directly related to its loudness. The greater the intensity, the louder the sound will be. This is because the higher intensity sound waves cause greater vibrations in our eardrums, resulting in a perception of a louder sound.

Can sound waves travel in a vacuum?

No, sound waves require a medium to travel through. In a vacuum, there are no molecules for the sound waves to vibrate and pass through, so they cannot travel. This is why sound cannot be heard in outer space.
