According to Einstein 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.
A black hole is a region of space-time exhibits a strong gravitational effect that nothing can escape from its sight.
A white hole behaves exactly opposite to a black hole.
we probably listen about the white holes in the theory of eternal black holes.
There are some similarities in between black hole and white hole, properties like mass, charge, and angular momentum.
They attract matter like any other mass, but objects falling towards a white hole would never actually reach the white hole’s event horizon.
In quantum mechanics, the black hole emits Hawking radiation and so can come to thermal equilibrium with a gas of radiation (not compulsory). Because 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.
How White Holes Form.
White holes are completely theoretical mathematical concepts. White holes were born as a solution to Einstein’s general relativity equation.
We still don’t know how they are formed. while many speculate that they are formed during later stages of a Black hole.
According to maximally extended Schwarzschild solution, the white holes event horizon in the past becomes a black holes event horizon in the future, so any object falling towards it will eventually reach the black hole horizon.
Interesting Things About a White Hole

- White Holes Violate the 2nd Law of Thermodynamics
- White Holes exist for Very Short Duration
- White Hole and Black Hole Together can create a Wormhole
- White Holes exist for Very Short
Duration Awhite hole behaves exactly opposite to a black hole.
The Known White Hole In the Universe!
In 2006, there was a gamma-ray burst (called 060614) that lasted for 102 seconds.
Usually, they have a short duration, so it was quite surprising to see on lasting for almost two minutes.
Five years after that incident, some scientists suggested that the gamma burst was a white hole.
The length and force of the outburst resonate with the idea of a white hole coming into existence, then imploding itself.
Not all astronomers accepted this theory, though it is a likely possibility.
