宇宙中有黑洞,还有白洞吗?
Ren Min Ri Bao· 2025-10-12 10:02
Core Concept - The article discusses the theoretical concept of white holes, which are the opposite of black holes, and explores their potential existence and implications in the universe [1][2][5]. Group 1: Black Holes - Black holes are formed when a massive star collapses within a critical radius, creating a region from which nothing, not even light, can escape [3]. - The existence of black holes was once doubted, but observational evidence since 1971 has confirmed their presence in the universe [3][4]. - The first image of a supermassive black hole was released in 2019, providing visual evidence of their existence [3]. Group 2: White Holes - White holes theoretically expel matter and energy, preventing anything from entering, and are mathematically related to black holes, differing only in the direction of time [3][4]. - There is currently no observational evidence for the existence of white holes, and some scientists question their formation mechanisms [5]. - Some theories suggest that white holes could explain certain cosmic phenomena, such as the energy output of quasars or the origin of the universe itself [5]. Group 3: Theoretical Implications - Theories propose that black holes and white holes may be connected by wormholes, allowing for the possibility of interstellar travel [4]. - A new hypothesis suggests that when matter is compressed in a black hole, it could undergo a quantum rebound, potentially transforming into a white hole [6]. - If this theory holds true, every black hole in the universe could eventually become a white hole [6]. Group 4: Future Prospects - There is hope that white holes may one day be discovered, potentially opening a gateway to deeper exploration of the universe [7].

Group 1 - The article discusses the theoretical concept of white holes, which are considered the opposite of black holes, expelling matter and energy instead of absorbing them [2][3]. - Black holes were once doubted in their existence until observational evidence, such as the detection of a black hole in the Cygnus X-1 system in 1971, confirmed their presence [2][3]. - The mathematical relationship between black holes and white holes suggests that they share the same properties, with the only difference being the direction of time [2][3]. Group 2 - There is currently no observational evidence supporting the existence of white holes, and some scientists argue that there is no reasonable mechanism for their formation [4]. - Some theories propose that white holes could explain certain cosmic phenomena, such as the energy output of quasars or even the origin of the universe, but these ideas lack observational support [4]. - A new hypothesis suggests that black holes could transform into white holes through a process of quantum rebound when matter is compressed to its limits, potentially allowing every black hole in the universe to become a white hole in the future [5].
