Do We Need a New Dark Matter Model?
Season 9 Episode 21 | 16m 21s

We have no idea what dark matter is, other than it’s some source of gravity that is completely invisible but exerts way more pull that all of the regular matter. Dark matter constitutes 80% or so of the mass in the universe, which means we should really try to figure out what it actually is.
