Dark Flow

The video explores cosmic motion, focusing on the concept of dark flow, where galaxy clusters may be moving towards a point beyond the cosmic horizon. It discusses Galilean relativity and the cosmic microwave background (CMB), explaining how peculiar velocities are measured. The Sunyaev-Zel'dovich effects are detailed, showing how they help identify galaxy clusters. The controversy surrounding dark flow is addressed, with differing results from WMAP and Planck satellite data. Finally, Feynman diagrams and quantum interactions are discussed, highlighting their role in understanding particle physics.

Describe the role of the Planck satellite in studying the cosmic microwave background.
