Can you scream in space?

A: Sound is a mecanical wave, which means that it needs substance to travel through, such as air or water. In space, there is no air, so sound has nothing to travel through. If someone were to scream in space, the sound wouldn't even leave their mouths.


Can you talk in space?

When astronauts are out in space, they can whistle, talk, or even yell inside their own spacesuit, but the other astronauts would not hear the noise. In fact, the middle of space is very quiet. Sound travels in waves, and it moves at different speeds through air or water or other materials.

Can you hear your own voice in space?

No, you cannot hear any sounds in near-empty regions of space. Sound travels through the vibration of atoms and molecules in a medium (such as air or water). In space, where there is no air, sound has no way to travel.


What happens if you play sound in space?

Sound waves need to travel through air to produce a sound. As there is air on a spacecraft, musical instruments should still work. However, it might not work if you try to play outside of a shuttle or space station. On a violin or guitar, the strings would vibrate without producing a sound.

Is there absolute silence in space?

Sound does not travel at all in space. The vacuum of outer space has essentially zero air. Because sound is just vibrating air, space has no air to vibrate and therefore no sound. If you are sitting in a space ship and another space ship explodes, you would hear nothing.


Can You Hear a Scream in Space? | MythBusters Jr.



What does space smell like?

A succession of astronauts have described the smell as '… a rather pleasant metallic sensation ... [like] ... sweet-smelling welding fumes', 'burning metal', 'a distinct odour of ozone, an acrid smell', 'walnuts and brake pads', 'gunpowder' and even 'burnt almond cookie'.

Where is the loudest place on Earth?

It ranks Dhaka of Bangladesh as the loudest city in the world with a noise level of 119 dB, followed by Moradabad in India with 114dB and Islamabad in Pakistan with 105dB.

What happens if you cry in space?

However, as astronaut Chris Hadfield notes, in microgravity, "your eyes make tears but they stick as a liquid ball." In other words, astronauts technically can't cry. Sure, you can get a watery substance to come out of your eyes, but it doesn't fall like it ordinarily does on Earth.


What is the loudest sound in space?

Jim Fuller. The loudest sound in the universe definitely comes from black hole mergers. In this case the “sound” comes out in gravitational waves and not ordinary sound waves.

Why can nobody hear u scream in space?

A: Sound is a mecanical wave, which means that it needs substance to travel through, such as air or water. In space, there is no air, so sound has nothing to travel through. If someone were to scream in space, the sound wouldn't even leave their mouths.

Can two person hear each other in space?

So astronauts cannot hear each other in space as sound cannot travel in space. Q.


Can you hear a star explode in space?

Light does not require a medium to travel through but sound requires a medium, so it cannot be transmitted through space. That is why we are able to see the supernova explosions but cannot hear them. Was this answer helpful?

Does a black hole make sound?

In 2003, astronomers detected something truly astonishing: acoustic waves propagating through the copious amounts of gas surrounding the supermassive black hole at the centre of the Perseus galaxy cluster, which is now renowned for its eerie wails. We wouldn't be able to hear them at their current pitch.

Do guns work in space?

Fires can't burn in the oxygen-free vacuum of space, but guns can shoot. Modern ammunition contains its own oxidizer, a chemical that will trigger the explosion of gunpowder, and thus the firing of a bullet, wherever you are in the universe. No atmospheric oxygen required.


How far would a bullet go in space?

At 9000km altitude, escape velocity is about 7.1km/s. A rifle's muzzle velocity is around 1km/s, so a bullet fired from a stationary position would either be caught in an orbit or eventually fall to Earth, depending on the direction of fire.

Can you hear radio in space?

Radio waves can travel through space. So, if you're wearing a space suit that contains a radio unit and one of your buddies sends you a radio message that there's pizza in the space station, you'd be able to hear it. That's because radio waves aren't mechanical -- they're electromagnetic.

How loud is a black hole?

Hailey et al.) For the first time in history, earthlings can hear what a black hole sounds like: a low-pitched groaning, as if a very creaky heavy door was being opened again and again.


What sound Cannot be heard in space?

No, there isn't sound in space.

This is because sound travels through the vibration of particles, and space is a vacuum. On Earth, sound mainly travels to your ears by way of vibrating air molecules, but in near-empty regions of space there are no (or very, very few) particles to vibrate – so no sound.

What's the loudest thing on Earth?

But what about the loudest sound ever heard? On the morning of 27 August 1883, on the Indonesian island of Krakatoa, a volcanic eruption produced what scientists believe to be the loudest sound produced on the surface of the planet, estimated at 310 decibels (dB).

Do bodies break down in space?

In space we can assume that there would be no external organisms such as insects and fungi to break down the body, but we still carry plenty of bacteria with us. Left unchecked, these would rapidly multiply and cause putrefaction of a corpse on board the shuttle or the ISS.


Can you laugh in space?

Astronauts can't cry the same in space as they do on Earth.

Astronauts can laugh in space all they want, but the act of crying is quite different without gravity.

Can you cry blood?

Crying bloody tears may seem like a fictional occurrence, but tears tinged with blood are an actual medical condition. Referred to as haemolacria, crying bloody tears is a rare condition that causes a person to produce tears tinged with, or partially made of, blood.

What is the loudest city in the US?

Polls show that Cincinnati, Ohio is ranked the loudest city in the U.S., with 86% of hotel-goers mentioning how loud the city was in their reviews.


What is the quietest thing in the world?

According to the Guinness Book of Records, the anechoic chamber at Orfield Laboratories in Minneapolis is the quietest place in the world, with a background noise reading of –9.4 decibels. If you chatted with someone, your speech would measure around 60 decibels on a sound-level meter.

What is the softest sound in the world?

The intensity of energy that these sound waves produce is measured in units called decibels (dB). The lowest hearing decibel level is 0 dB, which indicates nearly total silence and is the softest sound that the human ear can hear.
