Open inflation without anthropic principle

We propose the mechanism of quantum creation of the open Universe in the observable range of values of Ω. This mechanism is based on the no-boundary quantum state with the Hawking-Turok instanton in the model with nonminimally coupled inflaton field and does not use any anthropic considerations. Rather, the probability distribution peak with necessary parameters of the inflation stage is genera...

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...

The 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...

The 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...

Thermal inflation, baryogenesis and axions

In a previous paper, we proposed a simple extension of the Minimal Supersymmetric Standard Model which gives rise to thermal inflation and baryogenesis in a natural and remarkably consistent way. In this paper, we consider the λφ = 0 special case of our model, which is the minimal way to incorporate a Peccei-Quinn symmetry. The axino/flatino becomes the lightest supersymmetric particle with mã ...
