The physical basis of the modern cosmological inflationary models with baryosynthesis and nonbaryonic dark matter and energy implies such predictions of particle theory, that, in turn, apply to cosmology for their test. It makes physics of early Universe ambiguous and particle model dependent. The study of modern cosmology is inevitably linked with the probe for the new physics, underlying it. ...

SINCE ancient times, human beings have always pondered philosophical questions relating to living organisms, the planet Earth and the universe itself. What is life? Are human beings special living organisms? What is that twinkling star in the night sky? What is the universe? How big is the universe and where does it begin and end? These are just a few questions. However, these questions can har...

Abstract. How much of modern cosmology is really cosmography? How much of modern cosmology is independent of the Einstein equations? (Independent of the Friedmann equations?) These questions are becoming increasingly germane — as the models cosmologists use for the stress-energy content of the universe become increasingly baroque, it behoves us to step back a little and carefully disentangle co...

The standard model involves particle symmetry and the mechanism of its breaking. Modern cosmology is based on inflationary models with baryosynthesis and dark matter/energy, which involves physics beyond the standard model. Studies of the physical basis of modern cosmology combine direct searches for new physics at accelerators with its indirect non-accelerator probes, in which cosmological con...

Ancient origins of a modern anthropic argument against cosmologies involving infinite series of past events are considered. It is shown that this argument – which in modern times has been put forward by distinguished cosmologists such as Paul C. W. Davies and Frank J. Tipler – originates in pre-Socratic times and is implicitly present in the cyclical cosmology of Empedocles. There are traces of...

This research shows that a portfolio of wheat varieties could enhance profitability and reduce risk over the selection of a single variety for Kansas wheat producers. Many Kansas wheat farmers select varieties solely based on published average yields. This study uses portfolio theory from business investment analysis to find the optimal, yield-maximizing and riskminimizing combination of wheat ...
