Is there sound in a black hole?

For the first time in history, earthlings can hear what a black hole sounds like: a low-pitched groaning, as if a very creaky heavy door was being opened again and again.

Do black holes give off sound?

It actually generates ripples in that gas more properly classified as “sound” than the X-rays and other light from Messier 84. The trick for Nasa and the Chandra X-ray center was learning to shift the pitch of the Perseus black hole's sounds into the range of human hearing.

How loud is a black hole?

Converting the energy of 1,100 decibels to mass yields 1.113x1080 kg, meaning that the radius of the resulting black hole's event horizon would exceed the diameter of the known universe. Voila!

Can we create 1100 dB?

so to get 1100 dB, you need to explode 1*10^85 atomic bombs or 1 with 85 zeros on the right. Yes, that will create a blackhole.

What is the loudest thing in the world?

The Krakatoa volcanic eruption: Not only did it cause serious damage to the island, the eruption of Krakatoa in 1883 created the loudest sound ever reported at 180 dB. It was so loud it was heard 3,000 miles (5,000 km) away.

Do galaxies make sounds?

9+4438. You can see (and hear) the many galaxies orbiting each other like a swarm of bees, centered around a massive elliptical galaxy. Smaller or more compact galaxies produce short blip sounds while some elongated spiral galaxies create longer notes that can change pitch.

Can you hear sound 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.

Do you age in space?

In space, people usually experience environmental stressors like microgravity, cosmic radiation, and social isolation, which can all impact aging. Studies on long-term space travel often measure aging biomarkers such as telomere length and heartbeat rates, not epigenetic aging.

Do we age faster in space?

It's long been known that exposure to radiation damages DNA, but a new study has found an additional risk for astronauts: DNA replication is more prone to errors in microgravity.

Will a body decay in space?

In space we can assume that there would be no external organisms such as insects and fungi to break down the body, but we still carry plenty of bacteria with us. Left unchecked, these would rapidly multiply and cause putrefaction of a corpse on board the shuttle or the ISS.

Does Sun have sound?

The Sun does indeed generate sound, in the form of pressure waves. These are produced by huge pockets of hot gas that rise from deep within the Sun, travelling at hundreds of thousands of miles per hour to eventually break through the solar surface.

Is there sound on the moon?

However, the Moon is in space, and space is mostly a vacuum (there are always some atoms floating around, but they are VERY far apart and don't interact with one another). Thus there is no sound on the Moon.

Why is space a vacuum?

By definition, a vacuum is devoid of matter. Space is almost an absolute vacuum, not because of suction but because it's nearly empty. Related: What would happen if you shot a gun in space? That emptiness results in an extremely low pressure.

Is a black hole a hole?

No, a black hole is not really a hole at all. A black hole is an object just like any other, except that it is extremely dense. This gives it such a high gravitational field that nothing, not even light, can escape.

What do black holes look like?

Black holes themselves are entirely dark and featureless. The giant ones at the centers of galaxies are also surprisingly small, despite containing millions or billions of times the mass of our sun. To make observing them yet more difficult, those giants are shrouded in clouds of dust and gas.

Can you smell a fart in space?

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 is the quietest sound in the world?

Typically, zero decibels sound pressure level (SPL) corresponds to 0.000002 Pascals — a measure of vibration or pressure waves that we really hear. So then, zero decibels is the smallest level of sound our ears can detect! So there's our answer, in its simplest form.

After walking on the Moon astronauts hopped back into their lunar lander, bringing Moon dust with them. They were surprised, and perplexed, to find that it smelled like spent gunpowder.

How loud is space?

Studies on a single space shuttle flight found temporary partial deafness in the crew. Inside the International Space Station (ISS) it is so loud that some fear for the astronauts' hearing. At its worst, the noise level in sleep stations was about the same as in a very noisy office (65 decibels).

What does the sun smell like?

But the truth is that the sun itself doesn't have a smell — or if it does, we can't get a whiff of it. So what we're left with is the "smell" of outside air. And that's where the story gets interesting, because it turns out that air really does smell differently based on whether it's a warm, sunny day or a cold one.

Is there Colour in space?

Color does not change in space, because the wavelengths remain the same. Although you can see all the colors of the rainbow, plus every color mixture from those colors, you only have three color detectors in your eyes. These color detectors, called cones, have a preference for a particular type of light.
