An unidentified source of mass in the universe, a significant physics mystery that axions might explain.

Is Dark Energy made of Black Holes?
Sabine Hossenfelder
A form of matter that interacts gravitationally and makes galaxies rotate faster, comprising about 22% of the universe's energy density. It is distinct from dark energy.

Lex Fridman
A mysterious form of matter that accounts for about five times more mass than visible matter, inferred through its gravitational effects on galaxies.

Lisa Randall Interview (Full Episode) | The Tim Ferriss Show (Podcast)
Tim Ferriss
A type of matter that interacts gravitationally but not with light, making it 'transparent.' It constitutes about five times more energy than ordinary matter in the universe.
