Cosmologists have written a series of mathematical equations sometimes referred to as the Standard Model of Cosmology that attempts to describe the Universe as it is today. Working the equations backwards in time has allowed scientists to predict how the Universe started - the Big Bang. However, they've encountered problems along the way. One issue is that the Universe's temperatures are uniform - something at odds with the expected vast temperature variations. This conundrum led particle physicist Alan Guth to develop the inflation theory.
