The Big Bang — It's Still With Us (Physics)

Astrophysicists are fond of saying we are all made of stardust. How is it possible that material in the far reaches of the Universe could be related to us? In this seminar we explore the Big Bang theory, which explains how the first three minutes of the Universe created the material from which we are all made. We shall discuss how precise “relic abundances” (quantities of specific elements from the periodic table) are generated, and how this connects to other cosmological relics, such as dark matter and dark energy. Finally, we shall look at cosmic inflation and theoretical controversies about what might have preceded the Big Bang.
