As described in astronomy, black holes are regions of spacetime characterized by intense gravity where mass is concentrated into a very small space. As such, one might posit they are similar to other very dense heavy objects known or theorized in physical theory, such as, a quark star, a neutron star, or even a white dwarf. Depending on your viewpoint and how much wiggle-room you allocate to the word 'similar', there would also be arguments that a black hole is similar to its theoretical opposite, a white hole; or, to a particle, or even to our universe. Each of these, of course, has both significant differences as well as notional similarities.

Is there any black hole near your galaxy?

Yes, probably many of them. We believe that there is a supermassive black hole at the center of the Milky Way galaxy; that there are probably similar suoermassive black holes at the centers of many large galaxies.

What is the difference between a Scchwarzschild and a Kerr black hole?

A Schwarzschild black hole is a non-rotating black hole. The Kerr black hole is a rotating black hole. Since the latter is more complicated to describe, it was developed much later.A Schwarzschild black hole is a non-rotating black hole. The Kerr black hole is a rotating black hole.

What is the similar between tornado and a black hole?

well not that much they both spin and that's about it....wat different is that a tornado is sucking in air instead of a black hole it has emense gravity and what goes in a black hole is never seen again and with a tornado is just comes out is maybe a different form (morebeat up)


Does Stephen Hawking have prove that black holes are actually white?

Not exactly - What Stephen Hawking did was to promote a rationalization for an argument that black holes and white holes have similar natures. In quantum mechanics, the black hole emits Hawking radiation, and so can come to thermal equilibrium with a gas of radiation. Since a thermal equilibrium state is time reversal invariant, Stephen Hawking argued that the time reverse of a black hole in thermal equilibrium is again a black hole in thermal equilibrium. This implies that black holes and white holes are similar objects with the same nature. However the classical consideration for white holes is that they are the reverse of black holes and theoretically support the wormhole hypothesis by pairing a black hole with a white hole.

A black hole originated as a star, that is, the star converted to a black hole.

How do you create antimatter in powder toy 2?

I don't know, but the Void and Black Hole tools are similar to antimatter.


What does a black hole do with what it suck in?

The material sucked in to a black hole becomes part of the black hole - that is, a black hole crushes matter to an nearly no size, at all.
