The Universe

Matter & Radiation Dominance The Big Bang started off immensely hot! The time since the beginning of the universe is 1/H years or about 13.8 billion years. Radiation dominated the early universe. Matter dominance occurs after radiation “cools” enough for matter to condense per the relationship E=mc2.

Matter Dominance (today) The universe is composed mostly of matter. Most of the past 13.8 billion years has been dominated by matter. Our “horizon” is 13.8 billion light years away. During this period, the rate of expansion has been slowing (but for some recent findings!) In the past, H was much higher.

Radiation Dominance (early) Radiation dominated the early universe. The nature of the radiation was that of a black body radiator at an extremely high temperature. Remnants of the early universe are BB-like, but strongly red-shifted.
