What is the speed of sound in a black hole?

For a schwartzchild black hole, this suggests that the speed of sound everywhere except at the singularity would be zero (since a Schwartzchild black hole is nothing but a singularity and event horizon).

Can sound travel in a black hole?

Sound waves are NOT emitted from black holes. Nothing is emitted from black holes. No energy, no particles, nothing. Except (there is always an ‘except’) a statistical process known as Hawking Radiation; a very, very slow ‘leakage’ of virtual particles.

How deep is the sound of a black hole?

The voice of a black hole is a deep, deep bass, 57 octaves below middle C and far beyond the hearing range of humans. The Chandra X-ray Observatory has picked up sound waves for the first time from a cluster of galaxies 250 million light years away.

Did Sonic outrun a black hole?

The black hole appeared and Sonic was fast enough to run away from it… since it was powered by Hyper Go on Energy it’s much stronger. Not only was Sonic running away from it he did get sucked in as well but he survived the “tidal force” of the black hole as well.

What is the loudest noise in the universe?

The sound made by the Krakatoa volcanic eruption in 1883 was so loud it ruptured eardrums of people 40 miles away, travelled around the world four times, and was clearly heard 5,000 kilometers away. This is hailed as the loudest noise ever – and reported in Nautilus.

Do black holes suck in sound?

Black holes are certainly capable of pulling in those materials, with their sound waves. Sound needs a material medium (e.g. air, water, metal…) to be able to transfer within. Apparently a black hole will suck in the medium rendering sound waves existence impossible.

Do black holes hum?

Artwork depicting a binary black hole system, the precursor to a merger. And there are billions of them coming from the sky in all directions, from all those black holes everywhere in space, which means they all add up to a background hum of these waves arriving at Earth, like voices in a crowded room.

Can Sonic survive a black hole?

Can Sonic move faster than the speed of light?

Either Sonic can’t move at Light Speed, or everyone and their mother has light speed travel. 1. Sonic Adventure, Adventure 2 and Unleashed all state the Light Speed Dash is light speed. In Sonic Heroes and Generations he can do that without Light Speed Shoes, and the Light Speed Attack in the former.

Can sound be heard from a black hole?

Sept. 9, 2003: Astronomers using NASA’s Chandra X-ray Observatory have found, for the first time, sound waves from a supermassive black hole. The “note” is the deepest ever detected from any object in our Universe. The tremendous amounts of energy carried by these sound waves may solve a longstanding problem in astrophysics.

How fast can a black hole spin?

The laws of physics won’t let it spin any faster. And here’s the amazing part. Astronomers have actually detected supermassive black holes spinning at the limits predicted by these theories. One black hole, at the heart of galaxy NGC 1365 is turning at 84\% the speed of light.

Can we measure the pitch of a black hole?

So if we can measure the distance between the waves, we can determine the ‘pitch” of the black hole. Human ears can only hear sound waves that are close together and cycle very rapidly, so the sounds of this black hole are not something the human ear could detect.

Can a black hole vibrate?

The detection of these sound waves around the hole would also be a measurement of gravitational waves . I googled “vibrating black hole” . the first hit: A black hole can vibrate, and its vibrations produce gravitational waves (ripples in the fabric of spacetime).
