Thorne (1994) relates that this approach to studying black holes was prompted by the realisation by Hanni, Ruffini, Wald and Cohen in the early 1970s that since an electrically charged pellet dropped into a black hole should still appear to a distant outsider to be remaining just outside the event horizon, if its image persists, its electrical fieldlines ought to persist too, and ought to ...
The Penrose process (also called Penrose mechanism) is theorised by Sir Roger Penrose as a means whereby energy can be extracted from a rotating black hole. [1] [2] [3] The process takes advantage of the ergosphere – a region of spacetime around the black hole dragged by its rotation faster than the speed of light, meaning that from the point of view of an outside observer any matter inside ...
Astronomers said the V404 Cygni system holds a central black hole in the act of consuming a small star. This star appears to be very close to the black hole, orbiting it every 6.5 days, resembling ...
The theory predicts that Nature's parameters should be optimized for black hole production. Hence if one changes a coupling constant or a particle mass, the number of black holes should decrease. Theorists can analyze the effects of such a variation through calculations and computer simulations.
A binary black hole (BBH), or black hole binary, is an astronomical object consisting of two black holes in close orbit around each other. Like black holes themselves, binary black holes are often divided into binary stellar black holes , formed either as remnants of high-mass binary star systems or by dynamic processes and mutual capture; and ...
Or, the Big Bang was a supermassive white hole that was the result of a supermassive black hole at the heart of a galaxy in our parent universe. Shockwave cosmology , proposed by Joel Smoller and Blake Temple in 2003, [ 7 ] has the “big bang” as an explosion inside a black hole, producing the expanding volume of space and matter that ...
Black holes have a role in natural selection. In fecund theory a collapsing [clarification needed] black hole causes the emergence of a new universe on the "other side", whose fundamental constant parameters (masses of elementary particles, Planck constant, elementary charge, and so forth) may differ slightly from those of the universe where the black hole collapsed.
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.
