Our cosmic horizons. Part one: From the cradle of creation
- Harvard Univ., Cambridge, MA (USA)
This is the first article in a series of 4 on cosmological research. In this article the author looks at the origin of the universe and how conditions created in the Big Bang could have shaped the universe we seen today. We take it for granted that the universe contains galaxies, stars, planets, and people. And yet there is no good physical explanation for why any of these concentrations of matter should exist. One of the major problems with the Big Bang theory is that this theory cannot explain how matter built up from atoms to sizable chunks of material in a rapidly expanding universe. So why do galaxies exist Evidence indicates the answer might be found in the conditions that existed at the birth of the universe, when temperatures, pressures, and densities were far beyond what can be created in a laboratory, and bizarre physical processes that can only operate in such an environment might have given rise to much of what we see today.
