  2. Olbers's paradox - Wikipedia

    en.wikipedia.org/wiki/Olbers's_Paradox

    The first one to address the problem of an infinite number of stars and the resulting heat in the Cosmos was Cosmas Indicopleustes, a 6th-century Greek monk from Alexandria, who states in his Topographia Christiana: "The crystal-made sky sustains the heat of the Sun, the moon, and the infinite number of stars; otherwise, it would have been full of fire, and it could melt or set on fire."

  3. Multiverse - Wikipedia

    en.wikipedia.org/wiki/Multiverse

    A common feature of all four multiverse levels is that the simplest and arguably most elegant theory involves parallel universes by default. To deny the existence of those universes, one needs to complicate the theory by adding experimentally unsupported processes and ad hoc postulates: finite space, wave function collapse and ontological ...

  4. Many-worlds interpretation - Wikipedia

    en.wikipedia.org/wiki/Many-worlds_interpretation

    The quantum-mechanical "Schrödinger's cat" paradox according to the many-worlds interpretation.In this interpretation, every quantum event is a branch point; the cat is both alive and dead, even before the box is opened, but the "alive" and "dead" cats are in different branches of the multiverse, both of which are equally real, but which do not interact with each other.

  5. Kalam cosmological argument - Wikipedia

    en.wikipedia.org/wiki/Kalam_cosmological_argument

    In the B-theory, temporal passage and becoming are subjective and illusions of consciousness. Craig explains: [38] "On a B-Theory of time, the universe does not in fact come into being or become actual at the Big Bang; it just exists tenselessly as a four-dimensional space-time block that is finitely extended in the earlier than direction.

  6. The Hidden Reality - Wikipedia

    en.wikipedia.org/wiki/The_Hidden_Reality

    The simulated multiverse implies that technological leaps suggest that the universe is just a simulation. The ultimate multiverse is the ultimate theory, saying the principle of fecundity asserts that every possible universe is a real universe, thereby obviating the question of why one possibility – ours – is special. These universes ...

  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. Anthropic principle - Wikipedia

    en.wikipedia.org/wiki/Anthropic_principle

    The absurd universe: Our universe just happens to be the way it is. The unique universe: There is a deep underlying unity in physics that necessitates the Universe being the way it is. A Theory of Everything will explain why the various features of the Universe must have exactly the values that have been recorded.

  9. Infinity - Wikipedia

    en.wikipedia.org/wiki/Infinity

    The concept of infinity also extends to the multiverse hypothesis, which, when explained by astrophysicists such as Michio Kaku, posits that there are an infinite number and variety of universes. [56] Also, cyclic models posit an infinite amount of Big Bangs, resulting in an infinite variety of universes after each Big Bang event in an infinite ...
