Is space completely silent?
While space is more silent than you could ever imagine, it’s not completely devoid of sound. Sound waves cannot travel through space, but there are some infinitesimally small regions where sound can exist, under very specific conditions.
How does light and sound travel through space?
Sound cannot travel through empty space; it is carried by vibrations in a material, or medium (like air, steel, water, wood, etc). So, the sound wave gets smaller and smaller until it disappears. In contrast, light waves can travel through a vacuum, and do not require a medium.
Can sound travel in outer space why or why not?
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.
What would kill you first in space?
It’s a real thing: it’s called ebullism. Sure, you’ll look like the worst balloon animal ever, and you’ll feel pretty miserable, but you won’t be dead…at least not right away. Left unchecked, the inflated bubbles will cause significant tissue damage, but other things will kill you first.
Do we age faster in space?
So depending on our position and speed, time can appear to move faster or slower to us relative to others in a different part of space-time. And for astronauts on the International Space Station, that means they get to age just a tiny bit slower than people on Earth. That’s because of time-dilation effects.
Why can we see light in space but not hear sound?
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.
Does sound travel faster in space?
Does sound travel faster 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.
Why is space 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.
