Do white holes have a shorter lifespan than black holes?

White holes and black holes are theoretical objects in general relativity, and their properties are still a subject of active research and debate among physicists. While black holes are widely accepted and supported by observational evidence, white holes are purely speculative and have not been observed or confirmed.

According to current understanding, black holes are formed when massive stars collapse under their own gravity, resulting in a region of spacetime from which nothing, not even light, can escape. They have an event horizon, a boundary beyond which nothing can return. Black holes are characterized by their mass, charge, and angular momentum.

On the other hand, white holes are hypothetical solutions to Einstein's field equations that describe a region of spacetime where matter and energy can only escape and nothing can enter. They are often considered as time-reversed versions of black holes. However, there is currently no observational evidence for the existence of white holes, and their properties are still highly speculative.

Given the speculative nature of white holes, it is difficult to make definitive statements about their lifespan compared to black holes. The lifespan of a black hole is determined by its mass and the rate at which it emits Hawking radiation. According to Stephen Hawking's theory, black holes slowly lose mass over time due to the emission of this radiation. As they lose mass, their lifespan increases, and smaller black holes evaporate faster than larger ones.

Since white holes are purely theoretical constructs, their properties and lifespan are not well-defined. Some theories suggest that white holes, if they exist, could be connected to black holes through wormholes or other exotic mechanisms, but these ideas are highly speculative and not yet supported by empirical evidence.

In summary, while black holes have been extensively studied and are supported by observational evidence, white holes are still purely speculative and their properties, including their lifespan, are not well-understood.
