Can u hear 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.

How loud are black holes?

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 you feel a black hole?

What Would You Experience? If you were falling toward a black hole, most of the time you would simply feel weightless. The gravity of a black hole is just like the gravity of any other large mass, as long as you don't get too close.

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.

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 If You Fall into a Black Hole?

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.

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.

Can a black hole spin at the speed of light?

For the first time, astronomers have managed to measure the rate of spin of a supermassive black hole—and it's been clocked at 84 percent of the speed of light, or the maximum allowed by the law of physics.

How painful is a black hole?

The fate of anyone falling into a black hole would be a painful “spaghettification,” an idea popularized by Stephen Hawking in his book “A Brief History of Time.” In spaghettification, the intense gravity of the black hole would pull you apart, separating your bones, muscles, sinews and even molecules.

Are wormholes real?

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 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 noise ever?

The loudest sound in recorded history came from the volcanic eruption on the Indonesian island Krakatoa at 10.02 a.m. on August 27, 1883. The explosion caused two thirds of the island to collapse and formed tsunami waves as high as 46 m (151 ft) rocking ships as far away as South Africa.

CAN 1100 dB create a black hole?

With energy as great as 1100 dB, it would create enough gravity to cause a black hole to form, and an incredibly large one at that. Decibels are a logarithmic unit. That means 20 decibels isn't 2 times more powerful than 10 decibels, it's 10 times more powerful.

Do you think black holes are hot cold or neither?

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.

Does our sun orbit anything?

Does the Sun Orbit Anything? Yes! The Sun orbits around the center of our Milky Way Galaxy, which is a spiral galaxy. It's located about two-thirds of the way out from the center of the Milky Way which is about 28,000 light–years away.

What might happen if you got too close to the center of the Milky Way galaxy?

Q. What might happen if you got too close to the center of the Milky Way galaxy? You would be burned up by the galaxy's brightest stars.

Do charged black holes exist?

The two types of charged black holes are Reissner–Nordström black holes (without spin) and Kerr–Newman black holes (with spin). A black hole can be completely characterized by three (and only three) quantities: M – mass.

Can gravity bend light?

Gravity bends light

Light travels through spacetime, which can be warped and curved—so light should dip and curve in the presence of massive objects. This effect is known as gravitational lensing GLOSSARY gravitational lensingThe bending of light caused by gravity .

Is a black hole faster than the speed of light?

Using NASA's Chandra X-ray Observatory, astronomers have seen that the famous giant black hole in Messier 87 is propelling particles at speeds greater than 99% of the speed of light.

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 long is one minute in a black hole?

Black hole news: Standing on edge of black hole would cause 700 years to pass in 1 minute.
