White Holes?

Question

Do they exist and if so, are they just wormholes?

Answer 1

Large white holes do not exist.

When Einstein first thought up of black holes it was assumed that the matter had to come out somewhere; maybe in a white hole. Thanks to the work of Steven Hawking and others we know that black holes are dead ends the matter goes in and it stays there. Eventually it comes out as Hawking Radiation, but there is no white hole. A black hole is a bottomless bucket.

Quantum White Holes may exist.
According to String theory the fundamental stuff of the universe on the sub-sub-atomic scale is uneven, a quantum foam. This foam is composed of strings. Each string has a hole leading in and on the other side a hole leading out. The hole leading in is a quantum black hole and the hole leading our would be a quantum white hole. The idea of the string is that you enter the quantum black hole and at the same time you exit the quantum white hole. You travel across the interval in one instant; which is fine if you are moving single quarks or electrons around. However, if you are trying to move something more complex like a single atom then you need to get a series of strings that lead to the same spot all aligned in the same direction. That could lead to teleportation.

The strings would be wormholes, quantum wormholes.

Answer 2

a white hold is not a wormhole. Theoretically speaking, a white hole is the polar opposite of a black hole: it gives off copious amounts of energy. None have been observed in the universe, but if you think of the definition i just gave, it seems like the Big Bang could have been a form of a 'white hole'!

Answer 3

White holes are the theoretical antithesis of black holes. White holes were created on paper by mathemeticians by taking the equations of black holes and removing the mass from the equations. What you get is not a hole that sucks up energy and light which cannot escape, but you get a hole that emits that same amount of energy. A major problem with the possibility of white holes is that the moment any particle with mass, a dust particulate, gas molecules, anything comes into contact with it, it immediately would turn into a black hole. It also violates the first law of thermodynamics. So...white holes work on paper. They are mathematical constructs that actually make the math relatively simpler, as well as interesting. It just makes the meaning of the mathematics nonsensical.

Answer 4

White Holes are theoretical phenomena that spew the matter and energy consumed in a black hole. Black holes end a certain point called the singularity.
