Q&A 154: How Big are Meteors? And More...

The new season has begun! We're back with an all-new series of question shows. In this week's episode, I provide a quick guide to seeing fireballs (bolides), which are the brightest meteors you can see (and sometimes hear). I explain the philosophy behind Dyson Spheres, and explain why dark matter can't be made out of antimatter.
