Whilst the mass has a standard Newtonian interpretation, the spin does not, with the effect of nonzero spin leaving an indelible imprint on the space-time closest to the black hole. As a consequence of relativistic frame-dragging, particle orbits are affected both in terms of stability and ...
Black Hole Theory At the beginning of the lesson, the theories and theorists who discovered black holes were explained. In more recent years, new ideas and theories about black holes have been developed. One of these theories is from quantum physicists from Louisiana and Uruguay. Their theory ...
History and Theory The concept of an object from which light could not escape (e.g., black hole) was originally proposed by Pierre Simon Laplace in 1795. Using Newton's Theory of Gravity, Laplace calculated that if an object were compressed into a small enough radius, then the escape veloc...
Due to extreme gravitational influence, a black hole can distort space-time in the near neighborhood. According to the general theory of relativity, the closer you get to a black hole, the slower time runs. The event horizon is the boundary around the black hole where every matter, including...
According to this theory, a "direct collapse black hole" of this kind would have taken around 150 million years to form — the blink of an eye in cosmic terms. Another hypothesis invokes the idea of primordial black holes, which are theorised to have been created in the Big Bang itself...
theory with diffeomorphism invariance. The 4D−EL gravity not only covers the solution of 4-dimensional Einstein–Gauss–Bonnet gravity with the quadratic in curvature (e.g.,m̃=2) by the covariance and general method, but also contains the most general static 4Dblack-hole solution allowing ...

theory, and j ust half a century ago today - can be considered to mark the birth of black hole theory as a subject of systematic development by physicists of a new and less inhibited generation, whose enthusastic investigations have revealed structures of unforeseen mathematical beauty, even ...
The masses of primordial black holes that survive to the current day is likely to be larger than 1015g. Such a black hole would have aSchwarzschild radiusof 10−15m so it would be about the size of a proton. To investigate the detectability of such objects it is interesting to estimate...
