What's inside a black hole?

What is at the center of a black hole? At the center of a black hole, it is often postulated there is something called a gravitational singularity, or singularity. This is where gravity and density are infinite and space-time extends into infinity.

What is inside of Blackhole?

The singularity at the center of a black hole is the ultimate no man's land: a place where matter is compressed down to an infinitely tiny point, and all conceptions of time and space completely break down. And it doesn't really exist.

Is there anything in a black hole?

Don't let the name fool you: a black hole is anything but empty space. Rather, it is a great amount of matter packed into a very small area - think of a star ten times more massive than the Sun squeezed into a sphere approximately the diameter of New York City.

Is there life inside a black hole?

The short answer to the question is no because nothing can escape a black hole once it passes through the event horizon. There is, however, a theoretical possibility you can live inside of a black hole if you happen to enter a supermassive one.

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.

What's Actually Inside 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.

Is Earth in danger of a black hole?

Since this black hole already weighs a few million times the mass of the Sun, there will only be small increases in its mass if it swallows a few more Sun-like stars. “There is no danger of the Earth (located 26,000 light years away from the Milky Way's black hole) being pulled in.

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.

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.

What can escape a black hole?

Black holes are the blackest things in the universe. Because of their enormous, space-bending gravity, everything that falls into them is instantly ripped apart and lost. Scientists have never seen a black hole, because nothing, not even light, can escape them.

What is beyond a black hole?

At the center of a black hole the gravity is so strong that, according to general relativity, space-time becomes so extremely curved that ultimately the curvature becomes infinite. This results in space-time having a jagged edge, beyond which physics no longer exists -- the singularity.

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.

Is time Travelling possible?

Yes, time travel is indeed a real thing. But it's not quite what you've probably seen in the movies. Under certain conditions, it is possible to experience time passing at a different rate than 1 second per second. And there are important reasons why we need to understand this real-world form of time travel.

What comes out of a white hole?

Objects inside a white hole can leave and interact with the outside world, but since nothing can get in, the interior is cut off from the universe's past: No outside event will ever affect the inside.

Does gravity bend time?

The gravitational field is really a curving of space and time. The stronger the gravity, the more spacetime curves, and the slower time itself proceeds.

Should I be afraid of black holes?

Black holes are one of the most fascinating occurences in the universe, but they are nothing to be afraid of. A rogue black hole is not going to suddenly appear and destroy the earth, nor is the sun going to become a black hole. There is so much we don't know about black holes, and they should be studied, not feared.

Will our Sun become a black hole?

Will the Sun become a black hole? No, it's too small for that! The Sun would need to be about 20 times more massive to end its life as a black hole.

What do black holes eat?

The diet of known black holes consists mostly of gas and dust, which fill the otherwise empty space throughout the Universe. Black holes can also consume material torn from nearby stars. In fact, the most massive black holes can swallow stars whole.

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.

Would you see the end of the universe in a black hole?

No. The black hole will completely evaporate in finite time, so by the end of the universe it will no longer exist.

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.
