   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."

4. Borde–Guth–Vilenkin theorem - Wikipedia

   In 2017, Vilenkin stated that he does not think there are any viable cosmological models that escape the scenario. [9] Sean M. Carroll argues that the theorem only applies to classical spacetime, and may not hold under consideration of a complete theory of quantum gravity. He added that Alan Guth, one of the co-authors of the theorem, disagrees ...

5. Eternal inflation - Wikipedia

   en.wikipedia.org/wiki/Eternal_inflation

   The universes which are generated on the plane are described using a redefinition of the no-boundary wavefunction - in fact the theory requires a boundary at the beginning of time. [24] Stated simply Hawking says that their findings "imply a significant reduction of the multiverse" which as the University of Cambridge points out, makes the ...

6. Rare Earth hypothesis - Wikipedia

   en.wikipedia.org/wiki/Rare_Earth_hypothesis

   The Rare Earth hypothesis argues that planets with complex life, like Earth, are exceptionally rare.. In planetary astronomy and astrobiology, the Rare Earth hypothesis argues that the origin of life and the evolution of biological complexity, such as sexually reproducing, multicellular organisms on Earth, and subsequently human intelligence, required an improbable combination of astrophysical ...

7. Static universe - Wikipedia

   en.wikipedia.org/wiki/Static_universe

   In cosmology, a static universe (also referred to as stationary, infinite, static infinite or static eternal) is a cosmological model in which the universe is both spatially and temporally infinite, and space is neither expanding nor contracting. Such a universe does not have so-called spatial curvature; that is to say that it is 'flat' or ...

   A screengrab from the famous “GOFAST” video, which shows an infrared radar depiction of an object that remains unidentified by the Pentagon, but which is no longer considered anomalous.

9. Big Bounce - Wikipedia

   en.wikipedia.org/wiki/Big_Bounce

   The theory explains that the universe will expand until all matter decays and ultimately turns to light. Since nothing in the universe would have any time or distance scale associated with it, the universe becomes identical with the Big Bang, resulting in a type of Big Crunch that becomes the next Big Bang, thus perpetuating the next cycle.
