A rediscovered Einstein manuscript suggests light speed isn't constant after all — and a new experiment may prove his suppressed idea right, shaking the bedrock of modern physics.

Theory Briefing
- Einstein's 1905 special relativity enshrined a constant speed of light, a pillar that has anchored physics for over a century.
- A long-lost Einstein manuscript proposed that gravity could actually alter light's speed, contradicting his own landmark theory.
- A new experiment now claims to find evidence supporting the forgotten variable-light-speed idea, potentially forcing a revision of foundational physics.
