Reionization, public talk at ‘Skeptics at the Fringe’


Here is a public talk I gave at an Edinburgh fringe event, ‘Skeptics at the Fringe’.

I was talking about the ‘Epoch of Reionisation’ which is the period in time when the neutral Hydrogen in the Universe was ionised (again, hence the ‘re’) by the first stars.

Here’s a pdf of the talk, which was mostly made up of videos, either freely available on the internet or made by myself: reionisation_talk

The ones that I made myself were a couple of fun animations to show the process of stripping the electron from neutral Hydrogen.  They’re meant to be entertaining rather than scientifically accurate!
