Hour Two: Einstein,
Cosmology and the Speed of Light
What if Einstein was wrong? What if the speed of light wasn't constant,
but instead was variable? It's a bold idea, and one that might finally
lead cosmologists to the long sought after "theory of everything."
In this hour of Science Friday we'll take a look at the latest in
cosmology news, including a revised estimate of the age of the universe,
and evidence for dark energy.
