How is a white hole formed?
White holes are created when astrophysicists mathematically explore the environment around black holes, but pretend there’s no mass within the event horizon. What happens when you have a black hole singularity with no mass? White holes are completely theoretical mathematical concepts.
What is a white hole black hole?
A white hole is a time-reversed black hole – a region of space-time where matter spontaneously appears and explodes outwards, rather than implodes and disappears as with a black hole. Advertisement. White holes are essentially the opposite of black holes, in that they spit out light and matter, rather than trapping it.

What happens if a black hole meets a white hole?
So if a white hole and black hole collided, we’d have a massive black hole roaming around the Universe, destroying everything in its path.
What happens if we fall into a white hole?
They attract matter like any other mass, but objects falling towards a white hole would never actually reach the white hole’s event horizon (though in the case of the maximally extended Schwarzschild solution, discussed below, the white hole event horizon in the past becomes a black hole event horizon in the future, so …
Can a white hole exist?
White holes cannot exist, since they violate the second law of thermodynamics. General Relativity is time symmetric. It does not know about the second law of thermodynamics, and it does not know about which way cause and effect go.
Is time stopped in a black hole?
Near a black hole, the slowing of time is extreme. From the viewpoint of an observer outside the black hole, time stops. For example, an object falling into the hole would appear frozen in time at the edge of the hole.
Can a wormhole exist?
Einstein’s theory of general relativity mathematically predicts the existence of wormholes, but none have been discovered to date. A negative mass wormhole might be spotted by the way its gravity affects light that passes by.

White hole – Wikipedia
In general relativity, a white hole is a theoretical region of spacetime and singularity … White holes appear in the theory of eternal black holes.
What is a white hole? | BBC Science Focus Magazine
A white hole is a bizarre cosmic object which is intensely bright, and from which matter gushes rather than disappears. In other words, it’s the exact …

White Holes and Wormholes – JILA
The white hole is the region at the bottom of the diagram, bounded by the two red antihorizons. The black hole is the region at the top of the diagram, bounded …
Are white holes wormholes?
White holes may simply be the opposite end of black holes, connected by theoretical tunnels of space-time called (of course) wormholes. So the matter and energy falling into a black hole would eventually beam out of a white hole, somewhere in this or another universe.
Do white holes have gravity?
Its gravity is powerful. Light cannot escape it. Hence, a black hole’s blackness. White holes are the theoretical opposite of black holes.
Can you escape a white hole?
White holes are theoretical cosmic regions that function in the opposite way to black holes. Just as nothing can escape a black hole, nothing can enter a white hole. White holes were long thought to be a figment of general relativity born from the same equations as their collapsed star brethren, black holes.
What can destroy a black hole?
Black holes are among the most destructive objects in the universe. Anything that gets too close to a black hole, be it an asteroid, planet, or star, risks being torn apart by its extreme gravitational field. By some accounts, the universe may eventually consist entirely of black holes.

Whats at the center of a black hole?
The singularity constitutes the center of a black hole, hidden by the object’s “surface,” the event horizon. Inside the event horizon, the escape velocity exceeds the speed of light so that not even rays of light can escape into space.
Could a black hole be a wormhole?
Over the years scientists have looked into the possibility that black holes could be wormholes to other galaxies. They may even be, as some have suggested, a path to another universe.
Can black holes be portals?
According to a study published in Monthly Notices of the Royal Astronomical Society, a team of researchers seeking to prove the existence of wormholes say they may have found evidence that some known black holes in the universe are entrances to portals that could allow travelers to venture through space-time.
What is the nearest black hole to Earth?
| Distance | System | |
|---|---|---|
| (ly) | (kpc) | Designation |
| 5720±300 | 1.7±0.1 | XTE J1118+480 |
| 6000±375 | 1.86 ± 0.12 | Cygnus X-1 (Cyg X-1) |
| 7400±1500 | 2.3±0.46 | LB-1 |
Is there an opposite to a black hole?
White holes, which are theoretically the exact opposites of black holes, could constitute a major portion of the mysterious dark matter that’s thought to make up most of the matter in the universe, a new study finds. And some of these bizarre white holes may even predate the Big Bang, the researchers said.
Would you age slower near a black hole?
In short, a person near a black hole will age slower compared to someone far away from the black hole. This is because the passing of time is slowed down due to the extremely strong gravitational field near the black hole and thus, any physical aging processes will also happen slower.
Is time Travelling possible?
Yes, time travel is indeed a real thing. But it’s not quite what you’ve probably seen in the movies. Under certain conditions, it is possible to experience time passing at a different rate than 1 second per second. And there are important reasons why we need to understand this real-world form of time travel.
What happens if two black holes collide?
It is possible for two black holes to collide. Once they come so close that they cannot escape each other’s gravity, they will merge to become one bigger black hole. Such an event would be extremely violent. Even when simulating this event on powerful computers, we cannot fully understand it.
How many universes are there?
In a new study, Stanford physicists Andrei Linde and Vitaly Vanchurin have calculated the number of all possible universes, coming up with an answer of 10^10^16.

How many dimensions do we know of?
The world as we know it has three dimensions of space—length, width and depth—and one dimension of time. But there’s the mind-bending possibility that many more dimensions exist out there. According to string theory, one of the leading physics model of the last half century, the universe operates with 10 dimensions.
Is Dark matter real?
The phenomenon is called gravitational lensing. By studying how light is distorted by galaxy clusters, astronomers have been able to create a map of dark matter in the universe. A vast majority of the astronomical community today accepts that dark matter exists.
