Unfortunately for Einstein, all work done subsequently – including experiments that used springs – does point to the interference pattern disappearing when the photon's path is detected. In the latest ...

Usually, light waves can pass through each other without any resistance. According to the laws of electrodynamics, two light ...

The experiment showed that Bohr was definitely correct when he argued for complementarity, and that Einstein had got it wrong. The more atom-rustling that was measured, the weaker the diffraction ...

Scientists have shown that light can interact with itself in bizarre ways—creating ghost-like virtual particles that pop in and out of existence.

Penn State University scientists have demonstrated the complex series of events occurring inside thunderclouds that create ...

Light can behave in very unexpected ways when you squeeze it into small spaces. In a paper in the journal Science, Mark ...

Non-centrosymmetric halide perovskites are a class of semiconducting material containing a structural asymmetry with ...

This paper provides concrete evidence that the expanding and accelerating Universe mathematically expressed by dark energy is ...

Imagine two flashlights aimed at each other; do their beams collide? Nope! In everyday physics, light is too chill for drama.
