  2. Penrose process - Wikipedia

    en.wikipedia.org/wiki/Penrose_process

    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 ...

    However, Penrose determined that wave function collapse was a prime candidate for a non-computable process. In quantum mechanics , particles are treated differently from the objects of classical mechanics .

  7. Conformal cyclic cosmology - Wikipedia

    en.wikipedia.org/wiki/Conformal_cyclic_cosmology

    Conformal cyclic cosmology (CCC) is a cosmological model in the framework of general relativity and proposed by theoretical physicist Roger Penrose. [1] [2] [3] In CCC, the universe iterates through infinite cycles, with the future timelike infinity (i.e. the latest end of any possible timescale evaluated for any point in space) of each previous iteration being identified with the Big Bang ...

  8. Rotating black hole - Wikipedia

    en.wikipedia.org/wiki/Rotating_black_hole

    [7] [8] This can happen through the Penrose process inside the black hole's ergosphere, in the volume outside its event horizon. [9] In some cases of energy extraction, a rotating black hole may gradually reduce to a Schwarzschild black hole, the minimum configuration from which no further energy can be extracted, although the Kerr black hole's ...

  9. Penrose diagram - Wikipedia

    en.wikipedia.org/wiki/Penrose_diagram

    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.
