Cosmology: from the Big Bang to the formation of atoms
The whole Universe was in a hot dense state, then nearly 14 billion years ago expansion started. Wait... Is the Bang Bang true and how do we know? I will describe the observational evidence for Big Bang Cosmology and how it sets the initial conditions for every atom in the Universe. The talk is especially suitable for year 11 teachers and students studying VCE Physics Unit 1, area of study 3 "What is matter and how is it formed".
The Cosmic Microwave Background is a snapshot of the oldest light in our Universe, imprinted on the sky when the Universe was just 380,000 years old. It shows tiny temperature fluctuations that correspond to regions of slightly different densities, representing the seeds of all future structure: the stars and galaxies of today.
