Does space ever end?
It’s because of the shape of space.
Our part of space, or the observable universe, has a special shape: it is flat.
That means if you and a friend each had your own rocket ship and you both took off and travelled in a straight line, forever and forever, you would never meet..
How does sound travel 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. … Radio is a form of electromagnetic radiation just like light and can therefore travel through the vacuum of space just fine.
Is space really silent?
While the vast majority of space is a vacuum, and thus completely silent, there still are some areas that sound can be heard. … This sound was first recorded in 2003 at NASA’s Chandra X-ray Observatory, and it came from the Perseus galaxy over 250 million light years away.
What can sound not travel through?
vacuumSound cannot travel through a vacuum. A vacuum is an area without any air, like space. So sound cannot travel through space because there is no matter for the vibrations to work in.
What happens if you yell in space?
So, Alien has it right; while it’s not strictly true that sound waves can’t travel through space, it is true that humans would not be able to hear those sounds. Scream all you want, no one is hear you. … Radio waves can travel through space because they’re electromagnetic, not mechanical, and can travel through a vacuum.
Do planets make sounds?
Scientists have picked up “sounds” from solar system bodies, including radio waves from Saturn and vibrations in the magnetic field of Comet 67P/ Churyumov-Gerasimenko. The Mars 2020 rover may carry a microphone to the Red Planet, to make the first traditional sound recordings of another world.
Can sound travel in empty space?
Sound waves are travelling vibrations of particles in media such as air, water or metal. So it stands to reason that they cannot travel through empty space, where there are no atoms or molecules to vibrate.
What does space smell like?
“Space,” astronaut Tony Antonelli has said, “definitely has a smell that’s different than anything else.” Space, three-time spacewalker Thomas Jones has put it, “carries a distinct odor of ozone, a faint acrid smell.” Space, Jones elaborated, smells a little like gunpowder. It is “sulfurous.”
Can light travel forever?
If there were no objects to absorb light, it would keep traveling forever. Light is made up of particles called photons that travel like waves. Unless they interact with other particles (objects), there is nothing to stop them. … If it is infinite, the light would travel forever.
Can we hear sound from past?
Theoretically every sound you hear is from the past because it takes time for sound to travel. … Unlike light where a photon in vacuum can travel for ever (if it doesn’t hit anything) sound waves are simply disturbances in the medium, a series of energy pulses that move the particles of the medium (air.)
Is there noise on the moon?
However, the Moon is in space, and space is mostly a vacuum (there are always some atoms floating around, but they are VERY far apart and don’t interact with one another). Thus there is no sound on the Moon.
Do sound waves travel forever?
Sound waves do not live forever. … As the energy of the sound is transferred to more and more molecules of air, they vibrate less and less until the effect is lost in the constant random jostle of air molecules.
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 have a smell?
According to astronauts, they all smell like space. While each astronaut smells something a bit different, they all agree ‘space stinks’. Obviously, space is a vacuum, so no one has really ‘smelled’ it before in the traditional sense of the word. … But we can smell it indirectly.
Does space have a sound?
Space is a vacuum — so it generally doesn’t carry sound waves like air does here on Earth (though some sounds do exist in outer space, we just can’t hear them). But the various probes zooming through our cosmos are capable of capturing radio emissions from space objects.
Can you talk 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.
Can astronauts fart in space?
But if you’re an astronaut, every fart is a ticking time bomb. The gases in farts are flammable, which can quickly become a problem in a tiny pressurized capsule in the middle of space where your fart gases have no where to go.
Which travels faster than light?
Tachyons are hypothetical particles that travel faster than light. According to Einstein’s special theory of relativity – and according to experiment so far – in our ‘real’ world, particles can never travel faster than light.
