If black holes usually form when stars collapse, how do white holes form?

Nobody has ever observed a white hole.

A white hole is the time reverse of a black hole, and is thus forbidden due to the second law of thermodynamics.

To put it another way, we aren't going to be seeing any white holes out there for the exact same reason that we won't see scrambled eggs unfry and hop back in a shell.

Other universes? Seriously, there is no credible observational evidence of a white hole in this universe. That is the gold standard. Not everything that appears theoretically possible is known to physically exists in this universe.
 

What is a white hole?

A white hole is a hypothetical object in space that is the opposite of a black hole. While black holes suck in matter and light, a white hole would emit matter and light.

How do white holes form?

The formation of white holes is still a subject of debate among scientists. One theory suggests that they are formed when a black hole reaches the end of its lifespan and explodes, releasing all the matter and energy it has consumed. Another theory proposes that white holes have always existed and are connected to black holes through a cosmic tunnel.

Can we observe white holes?

Currently, there is no evidence to suggest that white holes exist in our universe. They are purely hypothetical objects and have not been observed or detected by any scientific instruments.

Do white holes violate the laws of physics?

The concept of white holes does not violate any known laws of physics. However, their existence has not been proven, and some theories about their formation and properties may require modifications to our current understanding of physics.

What would happen if we encountered a white hole?

If white holes do exist and we were to encounter one, it would most likely be a catastrophic event. The intense radiation and energy emitted by a white hole would be dangerous for any nearby objects. Additionally, the strange properties of white holes could have unpredictable effects on space and time.
