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.

Dark energy, the mysterious phenomenon that powers the expansion of the universe, may undergo periodic 'violent transitions' that reverse the growth of the cosmos, a new pre-print study hints.
