Some things are hard to see, like black holes. In this episode of Walkabout the Astroquarks discuss a couple of new observations that help us see the earliest stars in the universe and the supermassive black hole at the center of our galaxy. Plus: Josh struggles to understand superhero movies, Jim provides the trivia, and Addie, as always, is Charm.
Length Contraction, or Lorentz Contraction, is not just what happened after Hendrik Lorentz had a good time and rolled over to go to sleep.

Length Contraction. If things are feeling too long, just get a move on.
