Physicist Alan Guth, the father of cosmic inflation theory, describes emerging ideas about where our universe comes from, what else is out there, and what caused it to exist in the first place.

In 1981, physicist Alan Guth proposed the theory of cosmic inflation. It suggests that during the earliest moments of the universe, it expanded 10 26 times within 10 -36 seconds. The universe ...

The SPHEREx space telescope will explore the universe's origin and gather data on cosmic inflation.

In order to explain the fact that the universe today looks roughly similar everywhere, the physicist Alan Guth proposed in 1981 that the early universe underwent a period of accelerated expansion.
