Can Sound Waves Travel Through Space and Time?

Click For Summary

Discussion Overview

The discussion revolves around the question of whether sound waves can travel through space and time, exploring misconceptions about sound propagation and the nature of sound waves compared to electromagnetic waves. The scope includes conceptual clarifications and debates regarding the properties of sound in different media.

Discussion Character

  • Debate/contested
  • Conceptual clarification

Main Points Raised

  • One participant suggests that sound waves do not vanish but instead travel into outer space and remain there, prompting a search for ways to recover them.
  • Another participant counters this by stating that sound requires a medium to propagate and cannot travel through a vacuum, emphasizing that sound energy dissipates and becomes indistinguishable from random thermal motion.
  • A different participant proposes that the confusion may stem from mixing up sound waves with radio waves, which can propagate into space but do not return to Earth.
  • Another participant asserts that sound waves can only travel through air, reinforcing the idea that sound cannot travel through space.
  • One participant humorously questions the understanding of sound propagation by referencing cell phone technology, which relies on microwave-band radio waves.

Areas of Agreement / Disagreement

Participants express disagreement regarding the nature of sound waves and their ability to travel through space. There is no consensus on the initial claim about sound waves being recoverable from space.

Contextual Notes

Participants reference different types of waves (sound vs. electromagnetic) without resolving the distinctions clearly. The discussion includes assumptions about the nature of sound and its propagation that remain unexamined.

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.
 
um how do you think Cell-Phones Work ? LOL...

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