Ludicrous Listener

Ludicrous Listener is a Sun Badge given for watching 10 hours of video in a single topic. When earning this badge, it is common to earn around 50,000 Energy Points from a video you watched, depending on the length of the videos watched. No free energy points are given.

This badge is obtainable by watching all the Chemistry, Crash Course videos, or Talks and Interviews. It is hard to get because most of the videos are too short.
