Why is the universe flat?
131017 Like and subscribe. This is an archive, check the link in the end if you are. Cosmic inflation is a theory that was proposed in the 1980s by cosmologist Alan Guth to answer some of the most fundamental questions of the origins of our universe. It also solved the Horizon Problem and the Flatness Problem.
