In this episode, we tackle one of the greatest mysteries in modern astronomy: the universe's missing pull. When scientists realized that the visible matter in galaxies wasn't enough to generate the gravity keeping them intact, it sparked a massive cosmic debate.
We look back at the pioneering work of Vera Rubin and Kent Ford in the desert night, whose unexpected discoveries brought this "missing mass" problem to light.
To fix the math, mainstream science introduced an invisible, untraceable substance known as dark matter. But what if we don't need a mysterious new particle? What if the problem is that our understanding of gravity is wrong?
We dive into the controversial alternative known as MOND (Modified Newtonian Dynamics), which suggests that gravity changes its behavior when it gets incredibly weak.
It’s a fascinating, high-stakes detective story where the prize is figuring out what 85% of our universe is actually made of.
