What a black hole sounds like?

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.

Is a black hole quiet?

Researchers from the European Southern Observatory say this black hole is unique, because it does not react violently with its environment: it is silent, practically invisible and the closest black hole to Earth. They detail their findings in a study published Wednesday in the journal Astronomy & Astrophysics.

Would black holes be loud?

Black Holes: Incredibly Loud and Extremely Distant.

What you'd see if you fell into a black hole?

You would be able to see out from inside, but no-one would be able to see you because any light would fall back on you. The good news is that although the gravitational pull is much stronger than smaller black holes, the stretching tidal force is less, meaning you won't be turned into spaghetti.

What a black hole looks like inside?

Black holes have gravitational fields so strong that even light cannot escape, so they are defined by the shell of a black, featureless sphere called an event horizon. But the holes can nevertheless be seen. As they consume matter that strays too close, they squeeze it into a superheated disk of glowing gas.

Is there a white hole?

The short answer, unfortunately, is no. White holes are really just something scientists have imagined — they could exist, but we've never seen one, or even seen clues that one may exist. For now, they are an idea. To put it simply, you can imagine a white hole as being a black hole in reverse.

Does time stop in a black hole?

Time does stop at the event horizon of a black hole, but only as seen by someone outside the black hole. This is because any physical signal will get infinitely redshifted at the event horizon, thus never reaching the outside observer. Someone falling into a black hole, however, would not see time stop.

Would you feel pain in a black hole?

If you're falling into a stellar black hole, you'll start feeling uncomfortable within 6,000 kilometers (3,728 miles) of the center, long before you cross the horizon [source: Bunn]. Either way, spaghettification leads to a painful conclusion.

Can we see future in black hole?

Bottom line: simply falling into a black hole won't give you a view of the entire future of the universe. Black holes can exist without being part of the final big crunch, and matter can fall into black holes.

WHAT CAN 1100 dB do?

Apparently, a sound of 1,100 decibels would create so much energy, it would act as a immensely high quantity of mass. This would, in turn, create enough gravity to form an extremely large black hole! Larger, in fact, than our observable universe.

Can we produce 1100 dB sound?

You can't add them. You have to add the logarithm. so if 1 atomic bomb is 250 db, 5 atomic bombs exploding simultaneously is 250 + 10*log(5) = 257 dB. so to get 1100 dB, you need to explode 1*10^85 atomic bombs or 1 with 85 zeros on the right.

What is the loudest sound 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.

Are we rotating around a black hole?

Yes. All astronomical objects, including black holes, are formed by gravity pulling matter together. If a cosmic body originates from anything that had even the tiniest amount of rotational motion originally, then this spin rate will become greatly enhanced as the object collapses.

Is our galaxy spinning around a black hole?

So black holes cannot be the source of galaxy rotation: they are simply too small, and too far away from most of the galaxy to do it.

Are black holes magnetic?

Astronomers have found that the magnetic field strengths near supermassive black holes can be as strong as their intense gravitational fields. In fact, these magnetic fields are able to expel material from the vicinity of the black hole to form highly energetic outflows called 'jets'.

Are black holes hot?

Black holes are freezing cold on the inside, but incredibly hot just outside. The internal temperature of a black hole with the mass of our Sun is around one-millionth of a degree above absolute zero.

Do wormholes exist?

Wormholes are shortcuts in spacetime, popular with science fiction authors and movie directors. They've never been seen, but according to Einstein's general theory of relativity, they might exist.

Can a black hole become full?

No, in fact they are a result of something being filled too much. Black holes form when a colossal amount of material gets crammed into a tiny space that's much too small for it all to exist at once. When this happens, it collapses into something called a singularity.

What happens if two black holes collide?

It is possible for two black holes to collide. Once they come so close that they cannot escape each other's gravity, they will merge to become one bigger black hole. Such an event would be extremely violent. Even when simulating this event on powerful computers, we cannot fully understand it.

How many universes are there?

In a new study, Stanford physicists Andrei Linde and Vitaly Vanchurin have calculated the number of all possible universes, coming up with an answer of 10^10^16.

Can black holes be portals?

According to a study published in Monthly Notices of the Royal Astronomical Society, a team of researchers seeking to prove the existence of wormholes say they may have found evidence that some known black holes in the universe are entrances to portals that could allow travelers to venture through space-time.

What is on the other side of a black hole?

The discovery of light from the other side of a black hole was predicted by Einstein's theory of general relativity. But it has never actually happened before, and the discovery marks the first time that light has ever been directly observed coming from behind a black hole.
