What this talk is about

The Hang Theory. A lecture series by Hang Dallas.

One speaker. One big idea. One good room.

Where · 2700 SWISS Event Space.

Most of the universe is made of things we have never seen. Dark matter holds galaxies together. Dark energy pushes the cosmos apart. Together they account for 95 percent of everything, and no one has directly observed either one. Dr. Heidi Wu walks through what we know about these invisible forces, how cosmologists infer their presence, and why their nature remains one of the field's central puzzles.
