  • Summary

  • What is dark matter? Why do we need it, and how can we find it? Dark matter is notorious for how it evades detection, and its presence is one of the biggest mysteries in cosmology. Yet we think it must exist. Not only that, but we think it must make up 80% of matter in the universe.

    This episode I will explore how physicists discovered dark matter, what we know so far, and the particles which attempt to solve its secrets. Then I’ll consider what dark matter fails to explain and the possible alternative theories that complement dark matter’s weaknesses.
