Can you smell a fart in space?
In space, no one can hear you fart (but they can smell it).
Zero gravity could even help them to travel, if the aroma was spreading through a virtual vacuum.
Smells travel by the movement of individual aroma molecules..
Is sound louder underwater?
Sound that’s generated underwater stays underwater; very little sound passes from water to air. … But if you put your head under the water, the sound becomes much louder. You also feel more of a sound when you’re underwater. Above the surface, the sound waves only vibrate your eardrum (unless the sound is very loud).
Can you hear whales above water?
The sound this creates can be heard above and below the water. Lobtailing is when a humpback whale will hold their tail above the water and swing it around before slapping it on top of the surface of the sea. This is an action that also creates a sound that is heard, once again, both above and below the ocean.
Do planets make sounds in space?
NASA Space Sounds: what happens when spacecraft are used to record radio emissions from planetary environments, which are then converted to sound waves. Here’s something you don’t hear everyday. … More specifically, it’s a translation of electromagnetic vibrations from various planetary environments into sound.
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.
Why do you think outer 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 people hear you scream underwater?
You’ll be able to hear it clear as a bell from hundreds of feet away. Sound needs a medium to travel through (that’s why in the vacuum of space, no one can hear you scream), and sound moves four times faster through water than it does air.
Who wrote in space no one can hear you scream?
Dan O’Bannon”In space no can hear you scream” is the iconic tagline of Ridley Scott’s Alien. The original concept for Alien came from Dan O’Bannon, who wrote and co-starred in 1974’s sci-fi comedy Dark Star.
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.
How is space cold?
The reason outer space is so cold is because cold is what you get when there is no source of heat nearby. … Objects in space cannot cool off by thermal conduction or convection, but they can cool off by radiating infrared light. All objects do this, and they radiate more the hotter they get.
Is there sound on the moon?
NASA astronauts in orbit around the moon in 1969 heard a whistling sound described as “outer-spacy,” “weird,” and “eerie.” Recordings of the strange sounds are featured on the Science Channel show “NASA’s Unexplained Files,” which will air Tuesday night at 10 p.m. ET.
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.
Will a body decay in space?
If you do die in space, your body will not decompose in the normal way, since there is no oxygen. If you were near a source of heat, your body would mummify; if you were not, it would freeze. If your body was sealed in a space suit, it would decompose, but only for as long as the oxygen lasted.
Why can Noone hear you scream in space?
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 hear yourself 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.
