Can you hear a supernova from Earth?

Can you hear a supernova from Earth?

Sound itself can only be transmitted through a medium and so in space we cannot hear a supernova. However since a supernova is a giant explosion triggered by the final death throes of a massive star, if we could hear it, we would hear an incredibly loud blast.

Why can supernova explosions be seen but not heard on Earth?

Shikha said. “the explosion produce sound of frequency above 20,000 Hz hence they cannot hear it.”

How loud is a supernova if we could hear it?

A supernova would sound like 10 octillion two-megaton nuclear bombs exploding. When a star explodes, the massive detonation expels stellar material far into space, and that matter could theoretically provide a medium through which sound vibrations might travel.

Can you hear a star explode from Earth?

1. If a close enough star exploded would we ever be able to hear or even feel the explosion? The answer is maybe. There isn’t any sound in space, (contrary to what you might have heard in Star Wars), so any sound effects on earth would occur after the particles and light rays reached the earth’s atmosphere.

Why is 194 dB the loudest sound possible?

Strictly speaking, the loudest possible sound in air, is 194 dB. The “loudness” of the sound is dictated by how large the amplitude of the waves is compared to ambient air pressure. Essentially, at 194 dB, the waves are creating a complete vacuum between themselves.

What is louder than a supernova?

Since there is no sound in space a fart is louder than a supernova(star exploding)

What would a supernova explosion look like from Earth?

Life on Earth will be unharmed. But that doesn’t mean it will go unnoticed. Goldberg and Bauer found that when Betelgeuse explodes, it will shine as bright as the half-moon — nine times fainter than the full moon — for more than three months. “All this brightness would be concentrated into one point,” Howell says.

What is the loudest thing in the universe?

The 1883 Krakatoa volcano eruption was the loudest sound recorded on Earth, but there are much louder sounds in space, even though we technically can’t hear them.

Does space have an end?

Scientists now consider it unlikely the universe has an end – a region where the galaxies stop or where there would be a barrier of some kind marking the end of space.

What is the loudest car in the world?

According to Pretorius, the record for the loudest car in the world is held by their friend Scott van Riper in the US, who achieved 181.5 decibels. Pretorius said a project such as their Mini Cooper required financing and sponsorship.

Is it possible to hear a supernova in space?

Then they could talk, or possibly hear one another scream, or just make muffled noises under the face-hugger that had been hiding in their boot. There’s no sound in space, so you can’t hear what a supernova sounds like.

When did a supernova light reach the Earth?

So for argument’s sake, let’s say that a supernova’s light reached the Earth about 50 years ago, but it took place on the far side of the galaxy. To find that, we’d have to look for a nebula on the far side of the galaxy and that’s a hard thing to see.

Is it true that there is 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.

Can you see all of the supernovae in the Milky Way?

Surely we would be able to see all of the supernovae that happen in our Milky Way (no more than 100,000 light years away) with the naked eye, let alone with telescopes? Are some supernovae so much more super than others?
