Physicists created conditions where light only moves forward, generating stable rhythmic oscillations.

Light can go from point A to point B but not return — like a train on a loop. Such 'one-way' light was recently made to oscillate like a perpetual motion machine.

🎯 Rydberg atoms can reach the size of a bacterium — about 0.001 mm, which is thousands of times larger than a normal atom.

🎬 Similar rhythmic, never-damping oscillations are described in sci-fi as 'eternal clocks' or temporal anomalies.
