In Cosmic Jackpot, Davies argues that certain universal fundamental physical constants are precisely adjusted to make life in the Universe possible: that we have, in a sense, won a "cosmic jackpot," and that conditions are "just right" for life, as in The Story of the Three Bears. As Davies writes elsewhere, "There is now broad agreement among ...

The anthropic principle, also known as the observation selection effect, is the hypothesis that the range of possible observations that could be made about the universe is limited by the fact that observations are only possible in the type of universe that is capable of developing intelligent life.

Problem of the lack of evidence for alien life despite its apparent likelihood This article is about the absence of clear evidence of extraterrestrial life. For a type of estimation problem, see Fermi problem. Enrico Fermi (Los Alamos 1945) The Fermi paradox is the discrepancy between ...
One answer given by philosophers is the anthropic principle. If the universe came to exist by chance, and perhaps vast numbers of other universes exist or have existed, then life capable of physics experiments only arose in universes that, by chance, had very balanced forces.
[8] What is the origin of the stellar mass spectrum? That is, why do astronomers observe the same distribution of stellar masses—the initial mass function—apparently regardless of the initial conditions?

A Universe from Nothing: Why There Is Something Rather than Nothing is a non-fiction book by the physicist Lawrence M. Krauss, initially published on January 10, 2012, by Free Press. It discusses modern cosmogony and its implications for the debate about the existence of God .
Work started by Don Page and William Wootters [7] [8] [9] suggests that the universe appears to evolve for observers on the inside because of energy entanglement between an evolving system and a clock system, both within the universe. [10] In this way the overall system can remain timeless while parts experience time via entanglement.
