The universe is now 13,700 million yearsold, but the cosmic microwave backgroud radiation was formed when the universewas only 380,000 years old. "It means that we are now looking very far away and also very far back in time, before any galaxieshad formed. By doing so, we can find ...
The History of the Universe (Astronomers' Universe) This book gives an accessible account of the history of the Universe; not only what happened, but why it happened. An author of textbooks on the early Universe and inflation, David Lyth now explains both cosmology and the underlying physics ...

This relic of the Big Bang pervades the universe and is visible to microwave detectors, which allows scientists to piece together clues of the early universe. In 2001, NASA launched the Wilkinson Microwave Anisotropy Probe (WMAP) mission to study the conditions as they existed in the early ...
When this gas accretion process begins, it is very dramatic because the rate of accretion of gas is proportional to the square of the mass already accreted. In other words, the bigger it gets, the faster it grows. If gas could be continually fed to it, it would consume the Universe in...
but it inspired a lot of people. before long, other entries started popping up, and then one day someone made a wiki for it, so they wouldn't all 404 eventually. This was when /x/ was still young-ish, and The Holders, Ted the Caver, Treedog, and other old-school /x/ rubbish wa...

The QCD phase transition exhibits different periods during the evolution time of the universe. We explore the cosmological implications of QCD phase transition in the early universe, which was mainly full of QGP matter, through the Friedmann equations. This is performed by studying the effect of ...
