  2. Chronology protection conjecture - Wikipedia

    en.wikipedia.org/wiki/Chronology_protection...

    The chronology protection conjecture is a hypothesis first proposed by Stephen Hawking that laws of physics beyond those of standard general relativity prevent time travel—even when the latter theory states that it should be possible (such as in scenarios where faster than light travel is allowed).

    According to John Horgan, science journalist writing for The Wall Street Journal, Hawking, in his book, prefers string theory as a way of explaining the "theory of everything" (which Hawking predicts to be solved by "the end of this century") and, based on quantum mechanics, considers empty space as filled with virtual particles, "popping into ...

    en.wikipedia.org/wiki/Hawking_radiation

    Hawking radiation is black body radiation released outside a black hole's event horizon due to quantum effects according to a model developed by Stephen Hawking in 1974. [1] The radiation was not predicted by previous models which assumed that once electromagnetic radiation is inside the event horizon, it cannot escape.

  7. Theory of everything - Wikipedia

    en.wikipedia.org/wiki/Theory_of_everything

    Stephen Hawking was originally a believer in the Theory of Everything, but after considering Gödel's Theorem, he concluded that one was not obtainable. "Some people will be very disappointed if there is not an ultimate theory that can be formulated as a finite number of principles.

  8. Penrose–Hawking singularity theorems - Wikipedia

    en.wikipedia.org/wiki/Penrose–Hawking...

    The Hawking singularity theorem is based on the Penrose theorem and it is interpreted as a gravitational singularity in the Big Bang situation. Penrose shared half of the Nobel Prize in Physics in 2020 "for the discovery that black hole formation is a robust prediction of the general theory of relativity".

  9. Eternal inflation - Wikipedia

    en.wikipedia.org/wiki/Eternal_inflation

    In 2018 the late Stephen Hawking and Thomas Hertog published a paper in which the need for an infinite multiverse vanishes as Hawking says their theory gives universes which are "reasonably smooth and globally finite". [22] [23] The theory uses the holographic principle to define an 'exit plane' from the timeless state of eternal inflation.
