Bang! Goes the Universe
Bang! Goes the Universe is a walking, talking, four-dimensional tour of the history, the people, and the science behind one of the greatest discoveries of all time: the Big Bang. This podcast is an attempt to demystify the science behind big bang cosmology, by working through the developments in modern thought that slowly led us to our current state of play. I’ll hold interviews and labs to help you visualize various concepts along the way. And we’ll visit some of the people and places who are or were at the forefront of discovery in the field.

Episode 9
This Ancient Greek astronomer and mathematician built upon the suppositions of his predecessor creating a heliocentric model of the universe with the earth, moon and planets orbiting the Sun during the 3rd century BCE. Using an observation from Anaxagoras about the cause of eclipses, some geometry and some clever thinking, he devised a method of determining the size of the sun and moon and even took a stab at understanding their distances to the earth. His work would be built on further by Eratosthenes a century later.
