Walkabout the Galaxy
perception of space and time
Astrophysics and Astronomy | Physics
Astronomy and cosmology challenge our perceptions of space and time, make us ponder our place in the universe, and give us wonders from the infinitesimal to the nearly-infinite. Then there's Walkabout the Galaxy, where we attack the question of which is a bigger relative bite: when the Sun in its red giant phase swallows the Earth, or when Jim Cooney in his fishing phase swallows a gnat. For that and the other truly important questions, you can count on the Astroquarks. Walkabout the Galaxy: for the truly important questions in life.
Unlike our jolly green cousin, red giants are not to be toyed with. While we have a well-deserved reputation for goggling up planets, and can we point out that Sol will be joining us in a few billion years, together with a tasty helping of Mercury, Venus, and your own jolly green home, we are also the reason that your quaint little home exists in the first place. Red Giants, destroyers of worlds and planet-ing the seeds for the next generation, is proud to sponsor this episode. Be sure to keep an eye out for us, and keep a safe distance on your next Walkabout the Galaxy. Red Giants, I can't believe I ate the whole thing.
