How did the universe begin — and how is it expanding? CERN physicist Tom Whyntie has created a new TED-ED three animated video that explains how the universe began, why it’s expanding, and other basic phenomena that concern cosmologists and particle physicists. He shows how cosmologists and particle physicists explore these questions by replicating the heat, energy, and activity of the first few seconds of our universe, from right after the Big Bang.
