White holes are a hypothetical class of celestial objects that are postulated to be the opposite of black holes.
According to the theory, while black holes are capable of absorbing all the matter and energy around them, white holes, on the other hand, would expel matter and energy in an enormous way.
The idea of white holes is based on Einstein's equations of general relativity, which allow for theoretical mathematical solutions that indicate the existence of such objects.
It is believed that white holes could be the result of certain extreme cosmic events, such as the merger of two black holes.

However, it is important to note that so far no solid evidence for the existence of white holes in the universe has been found.
No direct observations have been detected and no distinctive signal has been found that can be attributed to these objects.
Furthermore, the existence of white holes raises a number of questions and contradictions.
For example, if black holes are able to absorb all the matter and energy around them, how could a white hole form and eject everything it has absorbed? What would be the physical mechanism behind this ejection?

Another interesting question is the relationship between white holes and time. According to some theories, white holes could somehow be connected to black holes through space-time tunnels called "wormholes".
However, this idea is still purely speculative and has not been proven.
