Chinese scientists claim they have made a converging energy beam weapon — but did they really, or have they been watching too ...

Can light itself, perhaps from a laser, cast a shadow? It might seem like a trick question, but the answer to this is "yes." ...

Can light itself cast a shadow? It may sound like a philosophical riddle, but researchers have found that under certain ...

International scientists, including a team from Heriot-Watt University, has announced plans to develop a revolutionary new ...

Scientists have shown that laser light, under certain conditions, can behave like an object and cast a shadow.

This could enable new tech for controlling light with light, opening doors to advanced fabrication, imaging, and illumination ...

Researchers have made a significant breakthrough by observing how light can block other light, creating a visible shadow. This remarkable phenomenon, seen for the first time in their experiments using ...

Abrahao from Brookhaven National Laboratory, researchers observed that under specific conditions, one laser beam can block ...

To ask if a beam of light can make a shadow sounds like a sort of Zen paradox, but physicists have demonstrated the possibility. They used a laser beam to block another laser beam, albeit with some ...

They found that the shadow's darkness increased proportionally with the power of the green laser beam, reaching a maximum ...

Researchers used a ruby crystal and specific laser wavelengths to demonstrate that a laser beam could obstruct light and ...
