Can you hear you scream in space?

A: 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 someone talking in space?

When astronauts are out in space, they can whistle, talk, or even yell inside their own spacesuit, but the other astronauts would not hear the noise. 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.

What have we discovered in space?

Since NASA’s inception in 1958, astronauts have landed on the moon, parked a robot-controlled rover on Mars, and discovered thousands of exoplanets—planets that orbit stars outside of this solar system. Scientists can even explore the 95\% of invisible space comprised of dark energy, dark matter, and dark radiation.

Can you shout in space why or why not?

With no molecules in the vacuum of space there is no medium for the sound waves to travel through. So there is no sound. And that is the reason nobody can hear you shout in space. Sound cannot travel in the vacuum of space.

What happens if u breathe in space?

The vacuum of space will pull the air from your body. Without air in your lungs, blood will stop sending oxygen to your brain. You’ll pass out after about 15 seconds. 90 seconds after exposure, you’ll die from asphyxiation.

How quiet is it in space?

Space isn’t completely quiet — in fact, it’s rather loud. That being said, if you scream in space, the sound will still technically travel; just at too low a frequency for our ears to be heard. In essence, there’s no medium for the vibrations to travel through.

Can you smell a fart in space?

Does it push the astronaut? Therefore, the fart will not be smelled by the astronaut, although they may marinate in it for a time. When astronauts are not in the space suit and floating about, the fart smell is exaggerated by the lack of airflow from the recycled air used and its inability to mask any smell.

What are the new discoveries in outer space?

They hunted through radio waves for mystery signals, discovered new galaxies and even figured out which alien star systems might be able to detect Earth.

• Radio emissions from an alien world.
• X-ray blobs bursting from the Milky Way.
• A long-lost rocket booster.
• Ghostly radio circles.
• A million new galaxies.

Does space make noise?

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 hear through your ears in outer space?

You wouldn’t have any air in your ears, so you couldn’t hear in the traditional sense. However, you might be able to make out a few sounds through bone conduction before the perils of space caused you to expire. In bone conduction, sound waves travel through the bones of the jaw and skull to the inner ear, bypassing the eardrum.

Why is there no sound in space?

They say that there is no sound in space and that it is because there is no air in space. For instance if someone were talking to you, you couldn’t hear what they were saying. Answer by Lynn: You’re right that there are gases in space, and it’s true that these gasses can propagate sound waves just like Earth’s air allows sound to travel.

Why can you hear radio messages in space?

So, if you’re wearing a space suit that contains a radio unit and one of your buddies sends you a radio message that there’s pizza in the space station, you’d be able to hear it. That’s because radio waves aren’t mechanical — they’re electromagnetic. Electromagnetic waves can transmit energy through a vacuum.

What will happen to the voice they hear from space?

On the ground, people get the signal and hear a voice. The voice they hear from space belongs to a child! This may sound like a science-fiction story. But it will really happen in February 2006. Don’t worry though. There won’t really be a student lost in space. In fact, no one will be in the space suit.
