Like black holes, white holes have properties such as mass, charge, and angular momentum.They attract matter like any other mass, but objects falling towards a white hole would never actually reach the white hole's event horizon (though in the case of the maximally extended Schwarzschild solution, discussed below, the white hole event horizon in the past becomes a black hole event horizon in ...

The negative T singularity is the time-reversed black hole, sometimes dubbed a "white hole". Particles can escape from a white hole but they can never return. The maximally extended Schwarzschild geometry can be divided into 4 regions each of which can be covered by a suitable set of Schwarzschild coordinates.
White hole may also refer to: Arts and entertainment "White Hole" , an episode of the television series Red Dwarf; White Hole, a 1979 Japanese experimental film by ...

In order to satisfy this requirement, it turns out that in addition to the black hole interior region that particles enter when they fall through the event horizon from the outside, there must be a separate white hole interior region that allows us to extrapolate the trajectories of particles that an outside observer sees rising up away from ...
Novikov put forward the idea of white holes in 1964. He also formulated the Novikov self-consistency principle in the mid-1980s, a contribution to the theory of time travel. Novikov moved to Copenhagen, Denmark, where he worked and taught at the Niels Bohr Institute. He returned to Russia in 2001.
In astronomy, the term compact object (or compact star) refers collectively to white dwarfs, neutron stars, and black holes.It could also include exotic stars if such hypothetical, dense bodies are confirmed to exist.
