Is there silence in space?

Sound does not travel at all in space. The vacuum of outer space
outer space
Outer space, commonly shortened to space, is the expanse that exists beyond Earth and its atmosphere and between celestial bodies.
https://en.wikipedia.org › wiki › 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.


Why space is completely silent?

In space, no one can hear you scream. This is because there is no air in space – it is a vacuum. Sound waves cannot travel through a vacuum. 'Outer space' begins about 100 km above the Earth, where the shell of air around our planet disappears.

Can u scream in space?

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.


How do astronauts talk if there is no sound in space?

Because there is nothing out in space (like an atmosphere), the sound waves from one astronaut's whistling can't travel over to the other astronaut's ears. That's why the astronauts use radios to communicate—even if they're floating in space right next to each other!

What does space smell like?

Astronaut Thomas Jones said it "carries a distinct odor of ozone, a faint acrid smell…a little like gunpowder, sulfurous." Tony Antonelli, another space-walker, said space "definitely has a smell that's different than anything else." A gentleman named Don Pettit was a bit more verbose on the topic: "Each time, when I ...


Mysterious 'Music' Heard in Outer Space



How cold is the space?

The Temperature of Deep Space

In the vast gulfs of space between stars and nebulas, however, scientists think there's a pretty uniform temperature of 2.7 degrees Kelvin, or -455 degrees Fahrenheit. Isn't space cool?

Can you cry tears 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.

Does suffocating in space hurt?

Just in case you were planning to jump out into the vacuum of space without a spacesuit, I urge you to reconsider. There's nothing but painful suffocation and death.


Can a gun be fired in space?

Yes. Bullets carry their own oxidising agent in the explosive of the cartridge (which is sealed, anyway) so there's no need for atmospheric oxygen to ignite the propellant.

What breaks silence of space?

The silence of space was broken by a sudden roaring sound of the river. Was this answer helpful?

Is it completely Dark in space?

Above the Earth's atmosphere, outer space dims even further, fading to an inky pitch-black. And yet even there, space isn't absolutely black. The universe has a suffused feeble glimmer from innumerable distant stars and galaxies. This artist's illustration shows NASA's New Horizons spacecraft in the outer solar system.


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.

Does space smell like burning?

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'.

What would smoke look like in space?

Without gravity, hot air expands but doesn't move upward. The flame persists because of the diffusion of oxygen, with random oxygen molecules drifting into the fire. Absent the upward flow of hot air, fires in microgravity are dome-shaped or spherical—and sluggish, thanks to meager oxygen flow.


Is it hard to fart in space?

With very little airflow in a small, compact space shuttle cabin, that funky smell lingers like an irritating housemate that doesn't pay rent. "Farts can kind of hang out. There's not as much airflow as on Earth.

Would your blood boil in space?

First, the good news: Your blood won't boil. On Earth, liquids boil at a lower temperature when there's less atmospheric pressure; outer space is a vacuum, with no pressure at all; hence the blood boiling idea.

What happens if you bleed in space?

In space, blood can splatter even more than it usually does on Earth, unconstrained by gravity. Or it can pool into a kind of dome around a wound or incision, making it hard to see the actual trauma. (Fun fact: If you are bleeding more than 100 milliliters per minute, you are probably doomed.


Why can't you burp in space?

In space, there is no gravity to pull things straight down, so the gas and liquids in the astronauts' stomachs don't seperate. This means the gas can't come back up to create a burp! Or, at least, a burp like we would known on Earth.

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.

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.


Would a person freeze in space?

Acute exposure to the vacuum of space: No, you won't freeze (or explode) One common misconception is that outer space is cold, but in truth, space itself has no temperature.

Why can't you see the sun in space?

In space or on the Moon there is no atmosphere to scatter light. The light from the sun travels a straight line without scattering and all the colors stay together.

How quickly would you freeze in space?

It's also very cold in space. You'll eventually freeze solid. Depending on where you are in space, this will take 12-26 hours, but if you're close to a star, you'll be burnt to a crisp instead. Either way, your body will remain that way for a long time.


How fast 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.
