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 ...
Penrose diagram of an infinite Minkowski universe, horizontal axis u, vertical axis v. In theoretical physics, a Penrose diagram (named after mathematical physicist Roger Penrose) is a two-dimensional diagram capturing the causal relations between different points in spacetime through a conformal treatment of infinity.
Within a small region, the horizontal compression balances the vertical stretching so that a small object being spaghettified experiences no net change in volume. Stephen Hawking described the flight of a fictional astronaut who, passing within a black hole's event horizon , is "stretched like spaghetti" by the gravitational gradient ...
The strong cosmic censorship hypothesis asserts that, generically, general relativity is a deterministic theory, in the same sense that classical mechanics is a deterministic theory. In other words, the classical fate of all observers should be predictable from the initial data.
By: Patrick Jones. A 30-year-long question about black holes has finally been resolved. Apparently, black holes twist space time like taffy. This finding is based off a principle put forward by ...
