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 event horizons bounding the black hole and white hole interior regions are also a pair of straight lines at 45 degrees, reflecting the fact that a light ray emitted at the horizon in a radial direction (aimed outward in the case of the black hole, inward in the case of the white hole) would remain on the horizon forever.
Mathematically, the conjecture states that, for generic initial data, the causal structure is such that the maximal Cauchy development possesses a complete future null infinity. The strong cosmic censorship hypothesis asserts that, generically, general relativity is a deterministic theory, in the same sense that classical mechanics is a ...
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 ...
In chemical kinetics, the substitution of a light isotope of an element with a heavier one typically results in a slower reaction rate. This is generally attributed to differences in the zero-point vibrational energies for chemical bonds containing the lighter and heavier isotopes and is generally modeled using transition state theory .
The hot accretion disc of a black hole, showing the relativistic effects imposed on light when it is emitted in regions subject to extreme gravitation.This image is the result of NASA simulations and shows a view from outside the horizon of a Schwarzschild black hole.
Q star (grey hole) A compact, heavy neutron star with an exotic state of matter where most light does not escape the star. V404 Cygni [5] Quark star: Star composed of quark matter or strange matter. 3C 58, PSR B0943+10, XTE J1739-285: Quasi-star: A conjectured star from the early universe with a black hole at its center. none
TIL that Great White Sharks across the Pacific Ocean consistently congregate at one specific spot in the Pacific Ocean. Scientists call this the White Shark Cafe. Image credits: zahrul3
