Is there such a thing as a white hole?

A white hole is a bizarre cosmic object which is intensely bright, and from which matter gushes rather than disappears. In other words, it’s the exact opposite of a black hole. But unlike black holes, there’s no consensus about whether white holes exist, or how they’d be formed.

Could black holes create new universes?

But that’s a big ‘might. ‘ A team of scientists has proposed a new theory where they do: Black holes might not only bend space and time into a singularity of extremely high density. …

Are black holes at the heart of most galaxies?

Astronomers are now fairly certain that these supermassive black holes are at the heart of almost every galaxy in the Universe. Furthermore, the mass of these black holes is somehow tied to the mass of the rest of the galaxy. They grown in tandem with each other.

Is dark matter made of black holes?

Dark matter is a mysterious substance composing most of the material universe, now widely thought to be some form of massive exotic particle. An intriguing alternative view is that dark matter is made of black holes formed during the first second of our universe’s existence, known as primordial black holes.

What are supermassive black holes?

The supermassive black holes, on the other hand, can contain hundreds of millions of times the mass of a star like our Sun. Astronomers are now fairly certain that these supermassive black holes are at the heart of almost every galaxy in the Universe. Furthermore, the mass of these black holes is somehow tied to the mass of the rest of the galaxy.

Will the Earth be pulled into the Milky Way’s black hole?

There is no danger of the Earth (located 26,000 light years away from the Milky Way’s black hole) being pulled in. Future galaxy collisions will cause black holes to grow in size, for example by merging of two black holes.
