Physics of Cosmic Dark Ages

Abstract

Najmuj Sahadat Sarkar

Basically in this paper I have tried to show how the Dark Age of our universe started. After the recombination phase of the Big Bang, the universe was shrouded in darkness for some 100 to 200 million years. At this time ordinary matter particles entered the structures created by dark matter. And their gravitational collapse helped create the massive structures in the universe today. All the large structures that we see in the universe today were once organized by the events that took place during the dark ages. Also towards the end of the paper I have tried to provide some observational data, both from gravitational lensing and WMAP satellites. Let's shed some light on the Dark Ages.
