Dark matter: it makes up 80 to 85 percent of the matter in the universe, it’s invisible, you can’t touch it, and according to this week’s guest astrophysicist Katie Mack, it’s probably passing through you right now.
Dark matter is weird.
On the show this week Indre talks to Mack about dark matter, dark energy, and the big bang.
