Is it completely silent in space?
While the vast majority of space is a vacuum, and thus completely silent, there still are some areas that sound can be heard.
An example of where sound in space occurs is within black holes, but unfortunately, it’s humanly impossible to hear..
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?
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 …
Has an astronaut ever been left in space?
Cosmonauts Georgi Dobrovolski (left), Vladislav Volkov (middle), and Viktor Patsayev (right), the only three people to die in space, are featured on three USSR stamps. On June 29, the cosmonauts loaded back into the Soyuz 11 spacecraft and began their descent to Earth. And that’s when tragedy struck.
Why Cannot we talk 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!
Can a grenade explode in space?
Yes, it would explode. Most hand grenades are nowadays triggered chemically, electrically or contain a fuze enclosed within the assembly, so they don’t require atmospheric oxygen to ignite, are watertight and otherwise more reliably go off at a preset time since activation.
Do astronauts drink alcohol in space?
Alcoholic drinks are generally disallowed in spaceflight, but space agencies have previously allowed its consumption. NASA has been stricter about alcohol consumption than the Roscosmos, both according to regulations and in practice. Astronauts and cosmonauts are restricted from being intoxicated at launch.
Would you be able to hear an explosion in space?
Sound needs a medium to travel (such as air), but space generally doesn’t have it. Therefore, sound can’t really propagate in space. So you can’t hear an explosion or any other sound in space.
Can you hear 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.
Would an explosion in space have a Shockwave?
A ‘shock wave’ is the disturbance of material that’s created when a wave moves through a medium at greater than the local speed of sound. Provided there is a ‘medium’ of sufficient density through which a shock wave can travel, there is no reason why shock waves can’t form in space.
Can a spaceship explode in space?
Yes, provided there is an oxidizer. A spaceship with liquid hydrogen and liquid oxygen will blow up quite well in the vacuum of space. Chemical explosives will also explode in space since they function by breaking weakly bonded chemical components; no oxygen is necessary.
What happens if a nuke goes off in the ocean?
Unless it breaks the water surface while still a hot gas bubble, an underwater nuclear explosion leaves no trace at the surface but hot, radioactive water rising from below. … During such an explosion, the hot gas bubble quickly collapses because: The water pressure is enormous below 2,000 feet.
Why can’t Two astronauts hear each other 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. … But two astronauts in space suits floating around in space will not be able to talk to each other directly no matter how hard they yell, even if they are only inches away.
What happens if there is an explosion in space?
If a nuclear weapon is exploded in a vacuum-i. e., in space-the complexion of weapon effects changes drastically: First, in the absence of an atmosphere, blast disappears completely. … There is no longer any air for the blast wave to heat and much higher frequency radiation is emitted from the weapon itself.
Why can’t we hear any sound on the moon?
The air here on Earth allows sound waves to move from one point to another (sound can also move through water, steel, earth, etc… it just requires that particles/atoms/molecules are touching one another). … Thus there is no sound on the Moon.
