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.
How fast does sound travel in space?
The speed of sound in a vacuum is
zero meters per second
, as sound cannot travel in a vacuum. Sound is a wave, which means it spreads through the vibration of particles in a medium, such as water or air. Since a vacuum is empty space, there is no medium for the sound to travel through.
Do we age faster in space?
Scientists have recently observed for the first time that, on an epigenetic level,
astronauts age more slowly during long-term simulated space travel than they would have if their feet had been planted on Planet Earth.
Is fire possible in space?
Fires can't start in space itself because there is no oxygen – or indeed anything else – in a vacuum
. Yet inside the confines of spacecraft, and freed from gravity, flames behave in strange and beautiful ways. They burn at cooler temperatures, in unfamiliar shapes and are powered by unusual chemistry.
Has NASA recorded sound in space?
The space agency used instruments on several probes (like Voyager and HAWKEYE) to record these waves. Then they put them together into a recording of a sound for all of us to hear. The result is a sound that is (frighteningly) akin to what you would expect to hear echoing as you sink into a black abyss.
Can you smell a fart in space?
In space, no one can hear you fart (but
they can smell it
). They can! 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.
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'.
How long is 1 year in space?
**One year in space would be
365 days
/1 year on earth…..
Is an hour in space 7 years on Earth?
The first planet they land on is close to a supermassive black hole, dubbed Gargantuan, whose gravitational pull causes massive waves on the planet that toss their spacecraft about. Its proximity to the black hole also causes an extreme time dilation, where
one hour on the distant planet equals 7 years on Earth
.
How long is 1 hour in space?
One hour on Earth is
0.0026 seconds
in space.
Would a flamethrower work in space?
You could use a flamethrower inside as spaceship to devastating effect if a flamethrower is specifically what you want
. However, if you want to attach a flamethrower to a spaceship that would not be the most effective use of a flamethrower or a spaceship.
Do astronauts menstruate in space?
Turns out
menstruating in space is not much different than it is on Earth
. Women have been living and working in space for decades now, and with no issues. But here's the problem: all available data on periods in space pertain to short-duration missions.
How cold is space?
Hot things move quickly, cold things very slowly. If atoms come to a complete stop, they are at absolute zero. Space is just above that,
at an average temperature of 2.7 Kelvin (about minus 455 degrees Fahrenheit)
.
Why we cant hear 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.
Can 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.
Does Earth make a sound in space?
How do astronauts wipe their bum?
Today, astronauts at the International Space Station go to the bathroom into a little plate-sized toilet hole, and
a fan vacuum sucks their excrement away
and a separate funnel equipped with a fan suction their pee away.
What happens if an astronaut floats off in space?
You'd possibly be spinning. In space, no kicking and flailing can change your fate. And
your fate could be horrible. At the right angle and velocity, you might even fall back into Earth's atmosphere and burn up
.
Can 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.
Does space have a bottom?
Space has no floor
.
However, it's not really an endless pit, either, because gravity doesn't pull in one direction. It pulls toward objects that have mass.
Do astronauts pass out during launch?
He also noted that
it's not possible to pass out during the launch
, because you are being pushed into space while lying on your back, so your blood doesn't end up draining out of your brain. Also, he said it takes about 15 seconds to go from a sunny day to complete darkness.
How dark is space?
How dark does space get? If you get away from city lights and look up, the sky between the stars appears very dark indeed. Above the Earth's atmosphere, outer space dims even further, fading to an inky pitch-black. And yet even there,
space isn't absolutely black
.
How much do astronauts get paid?
According to NASA, civilian astronauts are awarded a pay grade of anywhere from GS-11 to GS-14, so the income range is relatively wide.
Starting salaries begin at just over $66,000 a year. Seasoned astronauts, on the other hand, can earn upward of $144,566 a year
.
How much is a ticket to Mars?
In a conversation with the head of TED, Chris Anderson, published on Monday, Mr Musk reiterated that he aims to colonise Mars by building a self-sustaining city of a million people on the planet. In the past, Mr Musk has estimated that a ticket to Mars on a SpaceX flight would cost
between $100,000 and $500,00
.
How long does it take to get from Earth to the Moon?
It takes about
3 days
for a spacecraft to reach the Moon. During that time a spacecraft travels at least 240,000 miles (386,400 kilometers) which is the distance between Earth and the Moon. The specific distance depends on the specific path chosen.
