Cosmic inflation is a theory governing the dynamics of the early universe, moments after the grand cosmic event called the Big Bang. MIT physicist Alan Guth was the first one to propose the inflationary theory in the early 1980s however, it was later advanced by other influential physicists like Andrei Linde and Paul Steinhardt [1-3]. The theory mainly deals with the exponential expansion of space and subsequently the large-scale structure formation in the universe during its evolutionary stages. It is also suggested by the theory that the epoch of inflation lasted from 10−36 seconds to sometime between 10−33 and 10−32 seconds after the Big Bang. But in order to articulate the events following the Big Bang admirably, one needs to have a full-fledged quantum theory of gravity, which is yet a substantial challenge for physicists.
