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."
The argument can be used to explain why the conditions happen to be just right for the existence of (intelligent) life on the Earth at the present time. For if they were not just right, then we should not have found ourselves to be here now, but somewhere else, at some other appropriate time.
New inflation does not produce a perfectly symmetric universe due to quantum fluctuations during inflation. The fluctuations cause the energy and matter density to be different at different points in space. Quantum fluctuations in the hypothetical inflaton field produce changes in the rate of expansion that are responsible for eternal inflation.
Enter the realm of the multiverse and alternate realities, one of the most glorified canvases in popular culture's recent years — and a repository for the ache and longing of living in an era of ...
The measure problem in cosmology concerns how to compute the ratios of universes of different types within a multiverse. It typically arises in the context of eternal inflation. The problem arises because different approaches to calculating these ratios yield different results, and it is not clear which approach (if any) is correct. [1]
In science class, we always learned that all the planets in our solar system orbit around the sun. Scientists have figured out this is not necessarily true. Jupiter actually does not orbit the sun
