Abstract
Olbers’ paradox asks: Why is the sky dark?
But we can also ask: Why is the sky reionised?
During the Epoch of Reionisation, the first stars and galaxies were hard at work changing the phase space of the Universe: from neutral to ionised. But how do these sources of light (ionising radiation) perceive each other, and what lies betwixt and between them? In this talk, I will discuss the Epoch of Reionisation in the context of Olbers’ paradox and my own work and hopefully entertain you along the way!
