Sean Carroll: Distant time and the hint of a multiverse

At TEDxCaltech, cosmologist Sean Carroll attacks — in an entertaining and thought-provoking tour through the nature of time and the universe — a deceptively simple question: Why does time exist at all? The potential answers point to a surprising view of the nature of the universe, and our place in it.

We had the pleasure of having Sean Carroll as our guest on The Think Atheist Radio Show, on May 1st.

It was a great episode.
