Strange Universe 11/14/21

History's most famous eclipse happened in the same place in the sky as the lunar eclipse we saw a couple weeks ago. Einstein’s General Relativity theory said space can warp, so a star near the massive sun's edge should appear in a new, wrong place. And astronomer Arthur Eddington planned to confirm this from Africa by observing the 1919 solar eclipse, with the sun in front of the Hyades star cluster. Afterward he said he detected the tiny predicted star-shifts — and Einstein became an instant celebrity. This week we’ll hear from those who have dedicated their lives to the sky.
