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 ...
Kruskal–Szekeres diagram, illustrated for 2GM=1. The quadrants are the black hole interior (II), the white hole interior (IV) and the two exterior regions (I and III). The dotted 45° lines, which separate these four regions, are the event horizons. The darker hyperbolas which bound the top and bottom of the diagram are the physical ...
In these coordinates, the horizon is the black hole horizon (nothing can come out). The diagram for u-r coordinates is the same diagram turned upside down and with u and v interchanged on the diagram. In that case the horizon is the white hole horizon, which matter and light can come out of, but nothing can go in.
It doesn't take a degree in astrophysics or expertise on Albert Einstein to appreciate “White Holes,” theoretical physicist Carlo Rovelli's latest book. Rovelli liberally sprinkles quotes from ...
Fuzzball (string theory) – theorized by some superstring theory scientists to be the true quantum description of black holes. White hole – hypothetical region of spacetime which cannot be entered from the outside, but from which matter and light have the ability to escape. Naked singularity – gravitational singularity without an event ...
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.
Scientists studying the earliest black holes may have found an answer to dark matter, putting Stephen Hawking’s theory on the subject back into the spotlight. Scientists may have found an answer ...
This diagram gives the route to find the Schwarzschild solution by using the weak field approximation. The equality on the second row gives g 44 = −c 2 + 2GM/r, assuming the desired solution degenerates to Minkowski metric when the motion happens far away from the blackhole (r approaches to positive infinity).
