What is a white hole and how is it formed?
Black holes are created when stars, much more massive than our Sun, die catastrophically in a supernova. So then what’s a white hole? White holes are created when astrophysicists mathematically explore the environment around black holes, but pretend there’s no mass within the event horizon.
What is the power of white hole?
The user can create, shape and manipulate white holes, a hypothetical region of space-time where gravity prevents entry, but energy and matter can escape. Considered the antithesis of black holes, general relativity theory says white holes could form from spinning black holes.
What is in a white hole?
In general relativity, a white hole is a hypothetical region of spacetime and singularity that cannot be entered from the outside, although energy-matter, light and information can escape from it. White holes appear in the theory of eternal black holes.
Is a white hole a real thing?
White holes are the theoretical opposite of black holes. But further thought caused people to realize that white holes would be extremely unstable, and hence highly unlikely to exist, in fact so unlikely that no one has talked about them much in recent decades. They are truly fringe science.
Can a white hole exist?
Do we live in white holes?
There are no known physical circumstances that can lead to the existence of white holes. They are purely hypothetical (due to the math). Though Smolin says that they actually exist on the other side of black holes.
What are white holes?
White holes are theoretical cosmic phenomena that function in the opposite way as black holes; instead of attracting matter into an infinitely dense singularity due to immense gravity, it pushes out matter and light, preventing anything from re-entering past its event horizon.
What is the meaning of white hole in general relativity?
General relativity. In general relativity, a white hole is a hypothetical region of spacetime which cannot be entered from the outside, although matter and light can escape from it. In this sense, it is the reverse of a black hole, which can only be entered from the outside and from which matter and light cannot escape.
Is there a white hole in the future?
In addition to a black hole region in the future, such a solution of the Einstein field equations has a white hole region in its past. This region does not exist for black holes that have formed through gravitational collapse, however, nor are there any observed physical processes through which a white hole could be formed.
Is the black hole/white hole eternal?
The black hole/white hole appears “eternal” from the perspective of an outside observer, in the sense that particles traveling outward from the white hole interior region can pass the observer at any time, and particles traveling inward which will eventually reach the black hole interior region can also pass the observer at any time.
