The paradox of light: why it carries power without weight
In short: Light defies our everyday intuition by possessing energy while remaining massless. This video breaks down the fundamental physics—from Einstein's relativity to quantum mechanics—that explains how photons move through the universe.
The video explores the core principles of modern physics to resolve the mystery of light's properties. It connects the concept of energy to mass through the famous equation E=mc², while contextualizing how special relativity governs the speed of light and the behavior of spacetime.
Viewers will examine key experiments and theories, including the Double Slit Experiment, the Photoelectric Effect, and the Michelson-Morley experiment. The content bridges the gap between classical mechanics and quantum physics, touching on wave-matter duality and the Heisenberg Uncertainty Principle.
