'It invites us to reconsider our notion of shadow': Laser beams can actually cast their own shadows, scientists discover
After discussing the quirks in 3D modeling software, where a laser beam is treated as a solid object that can cast a shadow, scientists decided to experiment in real life — and found that laser beams can indeed cast a shadow under the right conditions.
Shadow of light? Scientists make laser beam cast shadow for the first time
This could enable new tech for controlling light with light, opening doors to advanced fabrication, imaging, and illumination techniques.
Scientists discover laser light can cast a shadow
Can light itself cast a shadow? It may sound like a philosophical riddle, but researchers have found that under certain conditions, a laser beam can act like an opaque object and cast a shadow. The discovery challenges the traditional understanding of shadows and opens new possibilities for technologies that could use a laser beam to control another laser beam.
Light itself casts a shadow in bizarre laser experiment
A new experiment has demonstrated something that sounds physically impossible – light itself casting a shadow. It turns out that if you manipulate a laser just right, then hit it side-on with another light source,
uOttawa physicists make laser cast a shadow
In a recent study, researchers from the University of Ottawa have demonstrated a remarkable new phenomenon: a laser beam casting a visible shadow.
Scientists Defy Conventional Physics By Revealing That a Laser Beam Can Cast a Shadow
Researchers create a visible shadow using only a laser beam, an achievement that seemingly defies conventional physics.
A Laser Beam Has Blocked Light – Are Lightsabers Next?
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 crystalline assistance.
Bizarre test shows light can actually cast its own shadow
With the help of a ruby cube and two laser beams, researchers made one ray of light cast a shadow when illuminated by the other
Scientists Discover Lasers Can Block Light And Cast a Shadow
Light shines; photons travel until they hit an object through which they cannot pass; this blockage creates a shadow, a little piece of darkness where the light has been impeded. Physicists, however,
