Black Holes: At the heart of a black hole is what's known as a singularity. This is a point in space where density becomes infinite and our current understanding of physics breaks down. Surrounding the singularity is the event horizon, an invisible boundary beyond which nothing can escape, not even light. Thus, any object that crosses this threshold is believed to be irretrievably consumed by the black hole. The concept of black holes emerged from Einstein's general relativity equations, and their existence has been confirmed through various astronomical observations.
White Holes: Theoretical and highly speculative, white holes are the conceptual opposites of black holes. While nothing can escape a black hole once past its event horizon, nothing can enter a white hole. They are believed to spew out matter and energy. Some have posited that a black hole and a white hole could be connected via a wormhole, a shortcut through spacetime. However, no observational evidence has been found for white holes, and their existence remains speculative.
Singularities: As mentioned, a singularity is the core
of a black hole. It's where matter is believed to be crushed to infinite density, and spacetime curvatures become extreme. General relativity predicts the existence of singularities, but such extreme conditions likely require a fusion of quantum mechanics and relativity for a complete understanding, which remains one of the biggest challenges in theoretical physics.
