Can black holes give birth to stars?

The black hole in Henize 2-10 is blowing new gas – which is moving at about 1 million mph (1.6 million km/h) –– into the region, triggering the birth of new stars.

Can a black hole give birth?

Astronomers have spotted a black hole "giving birth" to stars at the center of a nearby dwarf galaxy — and the stellar newborns are tethered to the black hole by a massive "umbilical cord" made of gas and dust.

Do black holes only come from stars?

Conventional black holes are formed by gravitational collapse of heavy objects such as stars, but they can also in theory be formed by other processes.

What happens when a black hole is born?

In the stellar remnants of a supernova, however, there are no longer forces to oppose that gravity, so the star core begins to collapse in on itself. If its mass collapses into an infinitely small point, a black hole is born.

Can a black hole create a universe?

The birth of our universe may have come from a black hole. Most experts agree that the universe started as an infinitely hot and dense point called a singularity.

What is a white black hole?

White holes are theoretical cosmic regions that function in the opposite way to black holes. Just as nothing can escape a black hole, nothing can enter a white hole. White holes were long thought to be a figment of general relativity born from the same equations as their collapsed star brethren, black holes.

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.

Is Earth in a black hole?

Read our answers to some of the big questions about black holes. Despite their abundance, there is no reason to panic: black holes will not devour Earth nor the Universe. It is incredibly unlikely that Earth would ever fall into a black hole.

Do white holes exist?

White holes cannot exist, since they violate the second law of thermodynamics. General Relativity is time symmetric. It does not know about the second law of thermodynamics, and it does not know about which way cause and effect go.

How are stars born?

A star is born when atoms of light elements are squeezed under enough pressure for their nuclei to undergo fusion. All stars are the result of a balance of forces: the force of gravity compresses atoms in interstellar gas until the fusion reactions begin.

Can a wormhole exist?

In the early days of research on black holes, before they even had that name, physicists did not yet know if these bizarre objects existed in the real world.

Do black holes create galaxies?

One clue comes from the observation that most galaxies contain massive black holes at their centers. That has led to the proposal that galaxies form around black holes which act as seeds for this process.

Is the Milky Way a black hole?

They saw stars whirling around a dark object at speeds up to a third of the speed of light. Their motions suggested that at the center of the Milky Way was a black hole 4 million times the mass of the Sun. Reinhard Genzel and Andrea Ghez later shared the Nobel Prize in Physics for this discovery.

Can a black hole swallow a galaxy?

No. There is no way a black hole would eat an entire galaxy. The gravitational reach of supermassive black holes contained in the middle of galaxies is large, but not nearly large enough for eating the whole galaxy.

Should we be scared 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.

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.

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.

Can you destroy a black hole?

Black holes are among the most destructive objects in the universe. Anything that gets too close to a black hole, be it an asteroid, planet, or star, risks being torn apart by its extreme gravitational field. By some accounts, the universe may eventually consist entirely of black holes.

What is opposite of black hole?

White holes, which are theoretically the exact opposites of black holes, could constitute a major portion of the mysterious dark matter that's thought to make up most of the matter in the universe, a new study finds. And some of these bizarre white holes may even predate the Big Bang, the researchers said.

What is the biggest black hole in the universe?

At the other end of the scale there is a true monster: the black hole at the center of the quasar TON 618. It possesses 66 billion solar masses, the most massive yet discovered.

What would happen 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.
