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.

From his home in the Egyptian city of Alexandria, he used a chance reading from a book at the library of Alexandria to devise a method of determining the shape and size of the earth. Not stopping there, he later determined the size and distance to the moon with fair accuracy and even attempted the same of the sun.
