Martin Rees formulates the fine-tuning of the universe in terms of the following six dimensionless physical constants. N, the ratio of the electromagnetic force to the gravitational force between a pair of protons, is approximately 10 . According to Rees, if it were significantly smaller, only a small and short-lived … Meer weergeven The characterization of the universe as finely tuned suggests that the occurrence of life in the universe is very sensitive to the values of certain fundamental physical constants and that the observed values are, for … Meer weergeven In 1913, the chemist Lawrence Joseph Henderson wrote The Fitness of the Environment, one of the first books to explore fine … Meer weergeven Some explanations of fine-tuning are naturalistic. First, the fine-tuning might be an illusion: more fundamental physics may explain the apparent fine-tuning in physical parameters in our current understanding by constraining the values those parameters … Meer weergeven • Philosophy portal • Abiogenesis – Natural process by which life arises from non-living matter • Clockwork universe – Deterministic model of the universe Meer weergeven Physicist Paul Davies has said, "There is now broad agreement among physicists and cosmologists that the Universe is in several respects ‘fine-tuned' for life". However, he continued, "the conclusion is not so much that the Universe is fine-tuned for … Meer weergeven Some scientists, theologians, and philosophers, as well as certain religious groups, argue that providence or creation are responsible for fine-tuning.

Our Improbable Existence Is No Evidence for a Multiverse

Webconstants should have been fine-tuned to make the emergence of life in the universe possible. This was first noticed by Brandon Carter,[1] and the notion was recently popularized in several books.[2,3] There are many physical constants such as the speed of light c, the gravitational constant G, Planck’s constant h, and Boltzmann’s constant k. Web2 dagen geleden · The physicists’ multiverse is usually presented in terms of some mind-bogglingly large but finite number of universes; for example, the number of universes consistent with a promising branch of string theory known as M-theory is 10 500 (1 followed by 500 zeros) – a number so colossal that the number of atoms in our universe (10 … rawburn fastball
