Conceptual illustration depicting matter transitioning from a black hole to a white hole. Black holes are regions in space-time where the gravitational force is so strong that even light cannot escape. Conversely, a white hole is a hypothetical region in space-time that is the opposite of a black hole. This signifies that nothing can enter it from the outside, but matter and energy would be ejected outwards. The possibility exists that a black hole might be connected to a white hole through a tunnel-like structure called a wormhole. However, this idea is purely theoretical, and there is currently no direct observational evidence to support it.
