What is the difference of white hole and black hole in astronomy?

Answer 1

From what ive gathered, black holes absorb in all matter and energy, then after an infinite amount of time bc of gravity affecting time flow, all the energy and matter gets shot out of the white hole

Answer 2

A black hole is a great mass that sucks matter into it. Nobody knows where that matter goes, but they do have some pretty good hypotheses. A worm hole is not in any way related to a black hole. In fact, a worm hole isn't even a hole! It is a tunnel that bends space and time in a way that if you could travel through a big enough worm hole, you could end up on a planet millions of light years away, 100 years in the past, and only have traveled through the hole in a matter of seconds! I hope my answer is good enough.

Answer 3

A black hole is an astrophysical object that is so dense that it sucks everything, including light, into itself. According to general relativity, a white hole is the "opposite" of a black hole; i.e. instead of sucking everything into it from its event horizon, it pushes everything away, not allowing anything to enter it.

Before we start talking about the theoretically speculated white holes, we need to describe the nearly unarguably realastrophysical objects known as black holes. How do we know that black holes exist? Well, we have two sources of evidence supporting this claim.

Firstly, we have data collected from the images of telescopes that is basically inexplicable unless black holes exist. Through the analysis of these images, we have observed objects that are in an orbit around something both dark and extremely massive. These massively dark objects seem to be very small in size relative to other objects of similar or greater mass that we can observe. Based on the solutions to Kepler's equations of planetary motion for the objects orbiting these dark, massive objects, they can onlybe black holes if we are to assume that general relativity is correct.

Secondly, we have a very good, well-tested theory of gravity that predicts the existence of such objects in the universe.

So, where do white holes come in?

Well, our theory of gravity, better known as Einstein's theory of general relativity, predicts the existence of black holes, because they are a particular solution to a set of equations known as the Einstein field equations. Exact solutions to these equations can be positive and negative. This is not unusual; indeed we see this sort of thing all the time in mathematics. For example, the solutions to y2 = 9 are y = 3 and y = -3.

Depending on your choice of sign for a particular solution to the Einstein field equations, you can get a black hole, which grows by sucking in matter from far away, or you can get the "opposite," a white hole, which is like a black hole running backwards in time.

So, what would a white hole look like? Well, if you somehow had a camera that could record a black hole sucking in matter, and then you played the recording in reverse, you'd see a white hole. You'd see matter being blown away from the white hole's event horizon, and the hole would gradually decrease in size as it spat this matter out. We're pretty certain that black holes are real, but does that mean that white holes real too?

Well, just because an equation that mathematically describes the universe has a negative solution as well as a positive one, doesn't necessarily mean that both of those solutions can describe actual events. For example, if I tell you that the square of the number of Baseball tickets that I have is 9, then, mathematically, I could have either 3 tickets or -3 tickets. However, -3 baseball tickets doesn't make any physical sense; there's no such thing. Additionally, there are plenty of examples of equations in dynamics where there are both positive and negative solutions with respect to time, but only one can describe the real world. This is because that, as we can see just by looking around us, time moves in one direction; time never reverses itself.

The white hole solution to Einstein's field equations is one of these types of solutions that doesn't apply to the real world. It's like having -3 baseball tickets; it just doesn't happen.

Answer 4

White hole is a hypothetical region of space time from which matter and light can escape. Generally it is believed that white hole is the reverse of a black hole but from a black hole No one can escape. White hole generally appear in the concept of eternal black hole which isn't form from the gravitational collapse but still the evidences of the formation of white hole isn't found

Answer 5

There are many differences between white holes and black holes. The difference between a white hole and a black hole is that a white hole has properties such as mass, charge, and angular momentum while black holes do not.

Answer 6

the direction matter is moving:

• matter falls into a black hole
• matter is ejected from a white hole

Answer 7

first of all THERE IS NO SUCH THING AS A WITE HOLE

Answer 8

worm holes take u to another galixy wile black holes take u rip u up and then make u into atoms and u r trappend ionsaide it forevether but anyways u nwill be died

Answer 9

Black holes are black and white holes are white

Answer 10

One difference is that we're pretty sure black holes actually exist. "Wormholes" in the cosmological sense are pure speculation bordering on fantasy.
