Anthropic Principle
The human body is a constant flux of thousands of chemical/biological interactions and processes connecting molecules, cells, organs, and fluids, throughout the brain, body, and nervous system. Up until recently it was thought that all these interactions operated in a linear sequence, passing on information much like a runner passing the baton to the next runner. However, the latest findings in...
متن کاملThe Anthropic Principle Revisited
The usage of the anthropic principle in modern cosmology is reviewed. It is argued that its recent use to explain the observed values of cosmological parameters as most probable values for an ensemble of universes, is not justified. However, the anthropic principle can be invoked to argue that a vast number of universes must exist, in which the cosmological parameters and constants of nature ta...
متن کاملThe Inverse Anthropic Principle
In the Middle Age, official science said wrongly we are in a very special location, but now it says we are living a special epoch. Indeed, in the famous article of Carr and Rees, 'The anthropic principle and the structure of the physical world', published by Nature (278, 605-612 (1979)) one reads “All these scales can be deduced directly from known physics except the mass and length scale of th...
متن کاملAnthropic Principle in Cosmology
A brief explanation of the meaning of the anthropic principle – as a prescription for the attribution of a priori probability weighting – is illustrated by various cosmological and local applications, in which the relevant conclusions are contrasted with those that could be obtained from (less plausible) alternative prescriptions such as the vaguer and less restrictive ubiquity principle, or th...
متن کاملThe density parameter and the Anthropic Principle
In the context of open inflation, we calculate the probability distribution for the density parameter Ω. A large class of two field models of open inflation do not lead to infinite open universes, but to an ensemble of inflating islands of finite size, or “quasi-open” universes, where the density parameter takes a range of values. Assuming we are typical observers, the models make definite pred...
