Dark matter

Three-part interview-style video discussion with Rocky Kolb about dark matter.

Part 1: Dark matter particles

What sort of things could dark matter be, and how would we tell which it is? Rafael Alves Batista and Rocky Kolb review the main candidate dark matter particles, and consider our chances for telling which one is out there.

Part 2: Why now?

We’re at a particularly interesting time in the evolution of the universe. Rocky Kolb and I chat about the interesting features of our time, and why we should–or should not–expect to be living now.

Part 3: Dark matter, fine-tuned

What surprising features of our theories cry out for explanation? Rocky Kolb and I consider features of our theories that look unlikely or unnatural, and what our chances are for building a unified theory that explains them.
