Understanding the Universe: Mysteries and Discoveries

The video explores the universe's mysteries, focusing on dark energy, dark matter, and matter-antimatter asymmetry. It introduces the standard model of particle physics and its limitations in explaining these mysteries. The Muon g-2 experiment at Fermilab is highlighted as a potential breakthrough in discovering new particles or forces that could solve these mysteries.

What unexpected discovery about the universe's expansion was made in the late '90s?

• The universe is contracting.
