Jakarta –
Outer space is a vast space and we cannot just explore it. However, if we could travel in outer space, would there be sound and we could hear it?
Collect IFL Science, sound is a vibration that propagates through a medium as a wave. Although in outer space there are not too many particles that can serve as a medium for transmitting sound, waves can still propagate.
The sun is constantly releasing particles known as solar wind streams. Scientists estimate the particle size is equivalent to 3 – 10 particles per cubic centimeter in Earth orbit.
Sound Travels through the Medium
Sound travels faster in liquids than in gases and faster in solids than liquids. Comparison of the speed of sound propagating in several of these mediums includes air (about 340 meters per second), water (1,480 meters per second), and iron (5,120 meters per second).
In another sense, sound will travel faster in the presence of plasma. Plasma waves are found everywhere in the universe where plasma exists because they are the most abundant matter in the universe.
The speed of sound in aggregation differs from that of the interstellar medium (gas present in interstellar space) and the turbulence of the plasma present in this gas has major implications for star birth.
The interior of stars is full of waves moving at sonic speed, much like an earthquake traveling through Earth. Astronomers can measure the sound by looking at small changes in the star’s brightness.
Voice Movement
Launching from the Washington State University website, a brain expert from the university, namely Allison Coffin, explained that the Moon has no sound, so astronauts use radio to communicate with each other.
He said that all kinds of sound travel through air, water, and other matter. The existence of these molecules make up the object so that it helps the sound travel.
Coffin learns more about how sound travels. It investigates hearing and hearing loss. He explained that when someone hears, there is something moving around where that person is.
The molecules that make up water or air collide with each other when they vibrate. They pass on their movement to neighboring molecules.
Sound Doesn’t Travel in Empty Space
Although sound does not travel through empty space, there are other places outside our planet where scientists have detected sound waves. For example, several scientists have used different machines to capture sound waves from gas clouds outside our atmosphere.
“In general, the sound is probably very low frequency, mega bass, so our ears can’t hear it,” said Coffin, quoted from the Washington State University website.
