Gravity Experiment Sparks Fresh Questions About Einstein's Constant Light Speed
Original: Einstein Said the Speed of Light Is Constant. But This Gravity Experiment Is Raising Questions
A new gravity experiment is raising questions about one of Einstein's foundational claims: that the speed of light is constant. The findings suggest that under certain gravitational conditions, the assumption may deserve closer scrutiny. Scientists are urging caution, noting that Einstein's relativity has withstood more than a century of testing, but the experiment is fuelling debate among physicists about how robust the theory's core postulates really are.
Why now: New experimental results challenging a core tenet of Einstein's relativity naturally attract wide scientific and public attention.
