Einstein's Biggest Blunder, Explained

The video explores Einstein's equation of general relativity, which relates mass, energy, and gravity, replacing Newton's law of gravitation. It discusses Einstein's solution for a simplified universe with constant density and the introduction of a cosmological constant to allow for a universe with matter. Friedman's alternative solution, which considers a non-static universe, is also covered. Modern discoveries reveal the universe's expansion, validating the cosmological constant's role, despite Einstein's initial dismissal of it as a blunder.
