Do supermassive black holes still exist?

Although there are only a handful of confirmed supermassive black holes (most are too far away to be observed), they are thought to exist at the centre of most large galaxies, including the centre of our own galaxy, the Milky Way.

What do supermassive black holes do?

A supermassive black hole (SMBH or sometimes SBH) is the largest type of black hole, with mass on the order of millions to billions of times the mass of the Sun ( M ☉). ... Accretion of interstellar gas onto supermassive black holes is the process responsible for powering active galactic nuclei and quasars.

What is the difference S between a stellar and supermassive black hole?

A typical stellar-class of black hole has a mass between about 3 and 10 solar masses. Supermassive black holes exist in the center of most galaxies, including our own Milky Way Galaxy. They are astonishingly heavy, with masses ranging from millions to billions of solar masses.

Are supermassive black holes larger than stellar mass black holes?

We have a supermassive black hole in the center of the Milky Way, and we call it Sagittarius A*. It has a mass about 4 million times that of the sun. Like I said, super massive. These beasts are easily a thousand times more massive than their stellar-mass cousins.

Can a black hole be bigger than a galaxy?

Astronomers Have Found A Black Hole 300 Times Bigger Than Our Milky Way Galaxy.

What happens if a black hole swallows Earth?

Will Earth be swallowed by a black hole? Absolutely not. While a black hole does have an immense gravitational field, they are only “dangerous” if you get very close to them. ... It would get very dark of course and very cold, but the black hole's gravity at our distance from it would not be a concern.

Did Einstein believe in black holes?

Over a century ago, Albert Einstein predicted that the gravitational pull of black holes were so strong that they should bend light right around them. Black holes don't emit light, they trap it; and ordinarily, you can't see anything behind a black hole.

Is anything stronger than a black hole?

Now if you fix the distance (say 150 million km), then the gravitational pull depends only on the mass of the object. A neutron star can be at most about three times the mass of the sun, black holes are nearly all larger than that, so the gravitational pull of the black-hole is greater.

What happens if Earth goes into a black hole?

The edge of the Earth closest to the black hole would feel a much stronger force than the far side. As such, the doom of the entire planet would be at hand. We would be pulled apart.

When our sun dies it will make a black hole?

First of all, the Sun is never going to turn into a black hole. Only the most massive stars become black holes at the end of their lives. Little stars, like the Sun, die in a different way. When these stars burn up all the hydrogen in their cores, they swell into red giants.

What is on the other side of a Blackhole?

Normal maps are useless inside black holes. At the event horizon - the ultimate point of no return as you approach a black hole - time and space themselves change their character. We need new coordinate systems to trace paths into the black hole interior.
