New research has uncovered an unexpected flaw in Einstein’s theory of relativity — a gap that no one had the tools to detect ...
They recreate how a camera would see objects traveling at 99.9% of the speed of light, revealing surprising relativistic ...
The speed of light has been one of science’s most trusted markers of stability. For more than a century, the idea that light ...
A single sewing needle is tiny enough to slip through fabric unnoticed, yet physics suggests that if it somehow struck Earth at light speed, the result would look less like a pinprick and more like a ...
If a very large disc on a frictionless, horizontal spindle were gradually rotated faster and faster, what would happen as the ...
In 1887, one of the most important experiments in the history of physics took place. American scientists Michelson and Morley ...
Several leading quantum gravity theories predict that there is a dependence of the speed of light on photon energy, which would bridge incompatibilities between general relativity and quantum physics.
