A Brief History of Everything, feat. Neil deGrasse Tyson

The video explores the universe's origin, starting with the Big Bang, the separation of forces, and cosmic inflation. It discusses matter-antimatter asymmetry, the formation of atomic nuclei, and the creation of elements. The formation of galaxies, stars, and the solar system is covered, leading to the emergence of life on Earth. The evolution of mammals and human intelligence is highlighted, emphasizing our connection to the universe.
