Exploring White Holes: Theoretical Opposites of Black Holes

White holes are theoretical cosmic bodies, the hypothetical opposites of black holes. Where black holes absorb matter, white holes are said to expel it, seemingly defying the laws of physics.

White holes emerge from Einstein's field equations as time-reversed black holes. They're solutions to the General Theory of Relativity, although no physical evidence supports their existence.

Despite their theoretical underpinnings, white holes have never been observed. Their properties suggest an explosive, short-lived presence, making detection highly unlikely with current technology.

Some theories suggest a black hole could transition into a white hole over vast timescales, possibly through quantum effects at the end of a black hole's life.

White holes might offer solutions to the black hole information paradox, where information seemingly lost in black holes could reemerge from a white hole.

Astrophysicists have speculated that some unexplained cosmic jets could be associated with white holes. However, this remains a contentious and largely speculative connection.

Remarkably, some scientists propose that the Big Bang itself might have been a supermassive white hole, with our expanding universe being the ejected material.
