  2. Multiverse - Wikipedia

    en.wikipedia.org/wiki/Multiverse

    Extreme multiverse explanations are therefore reminiscent of theological discussions. Indeed, invoking an infinity of unseen universes to explain the unusual features of the one we do see is just as ad hoc as invoking an unseen Creator. The multiverse theory may be dressed up in scientific language, but in essence, it requires the same leap of ...

    Tegmark and others [168] have argued that, if space is infinite, or sufficiently large and uniform, identical instances of the history of Earth's entire Hubble volume occur every so often, simply by chance. Tegmark calculated that our nearest so-called doppelgänger is 10 10 115 metres away from us (a double exponential function larger than a ...

    The sum of all potential parallel universes that constitute reality is often called the "multiverse". Another common term for a parallel universe is "another dimension", stemming from the idea that if the 4th dimension is time, the 5th dimension—a direction at a right angle to the fourth —is a direction into any of the alternative spacetime ...

    Assuming that space is roughly flat (in the sense of being a Euclidean space), this size corresponds to a comoving volume of about 1.22 × 10 4 Gpc 3 (4.22 × 10 5 Gly 3 or 3.57 × 10 80 m 3). [ 29 ] These are distances now (in cosmological time ), not distances at the time the light was emitted.
