“Although there are no observed white holes within our Universe, the theoretical description of one has many facets in common with what we identify as the hot Big Bang. There could be a connection between white holes and what happens on the other side of black holes, with implications for the origins of our own Universe.” (BigThink, Ask Ethan: Do white holes, the opposite of black holes, physically exist?)
The existence of white holes is uncertain. No confirmed observations of white holes exist. That phenomenon should be the opposite of black holes. It should be. End of the wormhole. Mathematically, that event exists. But the problem is that nobody has seen it yet. Theoretical gravitational wormholes are channels through space and time.
But why can’t we see white holes? The easy answer should be. That. They don’t exist. But then we can start to think about other possibilities. There is a possibility. That even if white holes exist. They are not similar objects to stars or black holes. This means that if the wormhole is like a spring. And if that structure acts like a spring.
That means. When the end of the wormhole closes, the structure starts to open like a serpent. This means that the structure loses its density. And. Let’s energy travel out from it more slowly. Than we even imagine. That means the wormhole is a leaking tube.
And it leaves energy over a longer distance. This means that the white hole might not have a sharp-edged shape like black holes. There is a possibility. The white hole sends out high-energy gamma photons, so we cannot see those photons or the white hole. And that causes an interesting thought. What if a white hole is invisible?
Another possibility is even more interesting. That possibility is that. If. A white hole is the opposite version of a black hole. That causes an effect. Where. Matter and energy come out from the wormhole to form a bubble. So. Could the wormhole be responsible for the cosmic voids?
Another version of this model is even more interesting. In this model, the thing is. Maybe energy. That travels in the wormhole. Just pushes the bubble ahead of it. This means that a wormhole and a white hole could exist. But we cannot see them. Because. All of them are outside the universe. This means that a wormhole pushes that bubble ahead of it. Until. It comes out of the universe.

Outside the universe, quantum resistance cannot keep that structure. Its form. The wormhole’s diameter can be less than a quark. This means that those hypothetical wormholes can be. The same. As hypothetical superstrings.
There is a model. In which dark energy forms in those hypothetical wormholes. The wormhole is structured so that the entropy is minimal. That allows information to travel faster than outside it. The best evidence of the wormhole's existence is the cosmic web. The galaxy filament. A giant megastructure that connects galaxy clusters. Those filaments can form only if there is a gravitational center.
The third and most fascinating idea is: maybe the white hole is anchored in time. This means that. The white hole is not bound in time like regular stars. So the white hole exists only at one point in time. When. We travel through time. The white hole’s location in time remains static. And we would see that event as a flash. But then we must realize. Maybe the white hole is an event. That. Connected with the black hole formation.
When we think about a black hole’s gravitation. Its. Escape velocity is higher than the speed of light. This means. Time dilation causes a situation where time travels backwards in the black hole’s event horizon. This means that a black hole transports information into the past. Or into a point in spacetime. Where the black hole formed. This. Is logical.
Einstein’s theory of relativity describes time dilation like this. Time moves slower. When. Speed rises. When speed reaches the speed of light. Time stops. And when speed crosses the speed of light. Time should start moving backwards. Gravity is directly compatible with speed. So, when escape velocity crosses the speed of light.
That means time moves backward. And that forms the model that a black hole itself is a white hole. In this model, the black hole itself transports information. Into. The point where it was born. We see a white hole as the flash of the supernova explosion. Those models are interesting. But they are only models. Direct observations are needed to confirm those events.
