A theory to end theories For the first time in the history of physics we therefore have a framework with the capacity to explain every fundamental feature upon which the universe is constructed.

This theory aligns well with observations of the cosmos such as the cosmic microwave background (CMB) and the ages of the oldest stars.

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.
