# How far can sound travel in space

## From about 80 to about 550 kilometers above the surface, the mean free path of a molecule is about a kilometer. That means the air at this altitude is about 59 times too thin for audible sound

There Actually Is Sound in Outer Space - Gizmodo From about 80 to about 550 kilometers above the surface, the mean free path of a molecule is about a kilometer. That means the air at this altitude is about 59 times too thin for audible sound

## If the sound waves travel too far they give all of their energy to increasing the temperature of the air (no matter how little the change is) and as a result the sound waves

Sound waves from atmospheric nuclear explosions were detected traveling around the world. In fact, they were detected going around several times, by my friend at Berkeley Pete Schwemin. How Far Have Radio Signals Traveled From Earth? Jul 26, 2011 · Deep space travel doesn’t require all that much in propulsive energy. Now the energy to support life, etc, would be far more… “It might actually be simpler to become a permanently space fairing species or to revive a dead planet on the cusp like Mars” Except that “reviving” mars might be impossible. The core of the planet is dead. Sound can leap across a vacuum after all | New Scientist Sep 29, 2010 · Sound can leap across a vacuum after all. So it stands to reason that they cannot travel through empty space, where there are no atoms or molecules to vibrate. How Has NASA Recorded Sound If Sound Cannot Travel In Space

Start studying Science: Light & Sound. Learn vocabulary, terms, and more with flashcards, games, and other study tools. Why can't sound travel through space How fast does light travel in milliseconds - Answers Jan 20, 2009 · Asked in Space Travel and Exploration How fast can a star travel ? All stars are stationary (they do not move) if you are asking "how fast does the light of a star travel" then the speed of light How Far Can Sound Travel And How? by charlina hamiora on Prezi Sound conduction (the process by which sound waves travel through a medium) through air is dependent on the temperature and the strength of sound, but sound can travel extremely far in air. -It is not known how far sound can travel through air,but what is known is that it can On Mars, No One Can Hear You Scream | Science | AAAS

Does that mean it could not exist in a vacuum? In outer space there is much less matter for sound to interact with so my question is, how does a sound generated in high matter places change as it travels to low matter places? For example, if you could NASA - 21st Century Explorer Jul 10, 2006 · Since early times, people have looked into space and wondered about its mysteries. The vastness of space has opened our minds, but its size has limited our search. We want to explore distant worlds, but how can we travel faster so we can go farther into space? How Far Can You Travel? - Universe Today

## When light hits a surface, its energy can be absorbed (soaked up), But unlike sound waves or water waves, it does not need any matter or material to carry its This means that light can travel through a vacuum—a completely airless space. As a result, laser light can be concentrated and controlled far more accurately.

Jun 30, 2015 · As far as I know sound is vibrating matter. Does that mean it could not exist in a vacuum? In outer space there is much less matter for sound to interact with so my question is, how does a sound generated in high matter places change as it travels to low matter places?

The vastness of space has opened our minds, but its size has limited our search. We want to explore distant worlds, but how can we travel faster so we can go farther into space?

### When sound travels through air, the atmospheric pressure varies periodically. of the space shuttle can produce a large pressure variation at a short distance of

Sound needs air molecules to travel. That's why no one would be able to hear you if you screamed in outer space. Billionaire entrepreneurs are trying to create rockets fit for human travel, while government agencies spend billions furthering their explorations. But we are still a long way off from making our way to the red planet. Space travel, the next generation. This need for speed will pose fresh obstacles. Since the Sun is large, the sound waves resonate at very deep frequencies -- typical resonant modes have 5 minute periods, and there are about a million of them going all at once. The resonant modes in the Sun are excited by something. That something is the tremendous broadband rushing of You’ve heard it before: In space, no one can hear you scream. That’s because sound doesn’t move through a vacuum, and everyone knows

On Demand News – To mark the Super Bowl, Nasa astronauts threw an American football down the length of the ISS, to see how far it would travel in zero gravity. Report by Nikhita Chulani. Sound waves require air to travel, and although the guitar string would certainly vibrate, no sound Now consider that our species started broadcasting radio signals into space only about a century ago. That's represented by a small blue bubble measuring 200 light-years in diameter surrounding the position of the Earth. For any alien civilizations to have heard us, they must be within the bubble. If you wanted to travel 100 trillion light years away, you could make the journey in 62 years. By the time you arrived, the Universe would be vastly different. It makes you wonder if space could be the same way. If you got in a rocket ship and traveled fast enough sound can't travel in space, how can we be hearing it? Звук не может путешествовать в космосе, как мы его слышим?

Sep 29, 2010 · Sound can leap across a vacuum after all. So it stands to reason that they cannot travel through empty space, where there are no atoms or molecules to vibrate. How Has NASA Recorded Sound If Sound Cannot Travel In Space Space is full of radio waves, plasma waves, magnetic waves, gravitational waves and shock waves, all of which can travel in space without a medium. These waves are recorded by instruments that can sense these waves, and the data is transferred to earth-based stations, where the waves are sound coded. Open-and-go lessons that inspire kids to - Mystery Science This unit helps students develop the idea that sound is an actual thing, a wave of vibrations traveling through the air. Equipped with this understanding, students can begin to make sense of how sound and music work. Less How Do Sound Waves Travel? | Sciencing Apr 24, 2017 · Sound waves can travel through any material, but not in a vacuum, which is why there is no sound in outer space. The speed of sound in air is about 330 m/s, meaning that it covers a mile in about five seconds. Sound actually travels at far quicker speeds in other media; for example, in biological tissues, it moves at 1,540 m/s.
