Veritasium
Veritasium explores why energy is not conserved in general relativity, using Emmy Noether's theorem linking symmetries to conservation laws. Physicists interviewed explain energy loss in an expanding universe.
Recommended as high-quality physics communication and as an introduction to Noether and energy non-conservation in cosmology.
