We also discovered that the Universe is continually expanding and becoming colder on average.

But what is its origin? Where do all the matter and radiation that pervade it come from? In short, how did the Universe come about? Science’s answers to this formidable question have not always been in agreement. There was a time, for example, around the middle of the last century, when scientists were divided into two opposing fields: the steady-state advocates, led by Fred Hoyle, and the Big Bang advocates, led…
