fine-structure

Over billions of light years and looking back billions of years in time, we now know that the fine-structure constant hasn't changed any more than about .001 percent.

And so it may well be that laboratory experiments that look for a tiny variation in the fine-structure constant, either over time of a year or while we orbit the sun - because while we orbit the sun we're moving through space, or as the sun moves through the galaxy we're also moving.

So this fine-structure constant is something that we can measure in the laboratory much, much more accurately, but we don't have the same time base.

We're going to now talk about the alpha, the fine-structure constant called alpha, with my guest Michael Turner, director of the Kavli Institute for Cosmological Physics, professor of physics at the University of Chicago.

A very good example of a coincidence that is too good to be true, and therefore a candidate for future physics principles, is the fine-structure constant.
