Stanford professor Andrei Linde is one of the main authors of the inflationary universe theory, a core explanation of what happened in the first moment of the Big Bang that created the universe.

As you no doubt have heard by now, yesterday a critical element of inflation was proved, at least experimentally, and the astrophysics world is giddy with excitement.

This video shows the moment when Professor Linde was told of these results, that his decades of hard work have finally borne fruit. A truly beautiful moment.
