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.
Is space completely silent?
How do astronauts hear sounds?
Why can’t astronauts hear in space?
What can astronaut hear space?
Do we age faster in space?
Previous research has shown that spending time in space causes bone density loss, immune dysfunction, cardiovascular issues such as stiffening of arteries, and loss of skeletal muscle mass and strength in both humans and rodent models. These changes resemble aging in people age on Earth, but happen more quickly.
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’.
Why we Cannot talk in 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.
Does space have a smell?
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 …
How noisy is 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.
Does space have an end?
No, they don’t believe there’s an end to space. However, we can only see a certain volume of all that’s out there. Since the universe is 13.8 billion years old, light from a galaxy more than 13.8 billion light-years away hasn’t had time to reach us yet, so we have no way of knowing such a galaxy exists.

Why can’t people cry in space?
Astronauts can’t cry the same in space as they do on Earth.
Your eyes make tears but they stick as a liquid ball. In fact, they sting a bit. So — space tears don’t shed.” Unless an astronaut wipes that water away, tears in space can form a giant clump that can break free of your eye, as The Atlantic explained.
Can you play music 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.
Will a body decay in space?
Inside a spacesuit, rigor mortis would still occur since it is the result of the cessation of bodily functions. And bacteria from the gut would still devour the soft tissues. But these bacteria need oxygen to function properly and so limited supplies of air would significantly slow down the process.
What is the loudest thing on Earth?
The loudest sound in recorded history came from the volcanic eruption on the Indonesian island Krakatoa at 10.02 a.m. on August 27, 1883. The explosion caused two thirds of the island to collapse and formed tsunami waves as high as 46 m (151 ft) rocking ships as far away as South Africa.
Does the multiverse exist?
Even though certain features of the universe seem to require the existence of a multiverse, nothing has been directly observed that suggests it actually exists. So far, the evidence supporting the idea of a multiverse is purely theoretical, and in some cases, philosophical.
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 a scream be heard 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.
Does silence exist 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.
What is forbidden in space?
The Outer Space Treaty
There is no claim for sovereignty in space; no nation can “own” space, the Moon or any other body. Weapons of mass destruction are forbidden in orbit and beyond, and the Moon, the planets, and other celestial bodies can only be used for peaceful purposes.
How many bodies are lost in space?
During spaceflight. As of March 2021, in-flight accidents have killed 15 astronauts and 4 cosmonauts, in five separate incidents. Three of them had flown above the Kármán line (edge of space), and one was intended to do so. In each case, the entire crew was killed.
