The Schwarzschild solution to Einstein's field equation of general relativity connects a black hole to a white hole via wormhole known as Einstein-Rosen bridge. The term "white hole" was later coined by Russian theoretical astrophysicist Igor Novikov in 1965, and the Schwarzschild metric also influenced Penrose diagram and Conformal Cyclic Cosmology. [1] [2] Compared to black holes, white holes have been less studied in astronomy, possibly for the greater difficulties in empirical research. The highly theoretical nature of white holes, however, did not prevent it from being of pure scientific interests to the Manhattan project scientists, among which there are J. Robert Oppenheimer, "the father of the atomic bomb", and John Wheeler, who gave the name to black hole. [3] [4]
Physical Properties
Stephen Hawking once expressed his observation on antimatter concentrations around black holes, when introducing his colleague and friend Roger Penrose, whose insights on the Cauchy hypersurface around black hole singularity won him the 2020 Nobel Prize in Physics. [5]
White holes were claimed to be observed in the NASA data on NGC 3034 by Yang Pachankis, who also claimed to have confirmed the plausibilities with another independent observational experiment.[6][7]
