The term "inflation" is also used to refer to the hypothesis that inflation occurred, to the theory of inflation, or to the
. The inflationary hypothesis was originally proposed in 1980 by American physicist
, who named it "inflation". It was also proposed by Katsuhiko Sato in 1981.
As a direct consequence of this expansion, all of the observable universe originated in a small
region. Inflation answers the classic conundrum of the Big Bang cosmology: why does the universe appear flat,
in accordance with the
when one would expect, on the basis of the physics of the Big Bang, a highly curved, heterogeneous universe? Inflation also explains the origin of the
large-scale structure of the cosmos
s in the microscopic inflationary region, magnified to cosmic size, become the seeds for the growth of structure in the universe (see
galaxy formation and evolution
While the detailed
mechanism responsible for inflation is not known, the basic picture makes a number of predictions that have been confirmed by observation. Inflation is thus now considered part of the standard hot
cosmology. The hypothetical
thought to be responsible for inflation is called the
