A physicist has proposed a bold experiment that could allow gravitational waves to be manipulated using laser light. By ...

While the concept of time travel has long captured public imagination, modern physics actually approaches time in a much more subtle manner. Instead o.

Researchers have developed a novel experimental platform to measure the electric fields of light trapped between two mirrors with a sub-cycle precision. These electro-optic Fabry-Perot resonators will ...

Breakthroughs, discoveries, and DIY tips sent every weekday. Terms of Service and Privacy Policy. There’s a gap on the electromagnetic spectrum where engineers can ...

A scattering-invariant mode of light is generated by a spatial light modulator. This modulated beam propagates through free space (top) or a strongly scattering medium (bottom) such that the pattern ...

University of Illinois Physics Professor Paul Kwiat and members of his research group have developed a new tool for precision measurement at the nanometer scale in scenarios where background noise and ...

The speed of light is a fundamental constant, approximately 299,792,458 meters per second. It's the same for all observers and hasn't changed measurably over billions of years. Nothing can travel ...
