On the Science Channel again, we watched a episode of Through the Wormhole narrated by Morgan Freeman. I believe this was episode 8 from the first season entitled Beyond the Darkness. The topic was dark matter and dark energy and featured a bit with Vera Rubin! Awesome! Great to learn a bit more about her. Curious timing, this show. I relayed the sad news about Ms Rubins to Mom.
A lot of people have been talking about her lately and saying she discovered dark matter. It's more appropriate to say that her research into the rotational patterns of spiral galaxies lead to the development of the dark matter theory. What she found make cosmologists throw out their old theories.
