Holography encodes light's amplitude and phase, creating 3D images with depth and realism, essential for advancements in ...

The film "Introduction to Holography" explains the principles of holography, focusing on how it differs from traditional photography by creating three-dimensional images. It discusses the role of wave ...

In a first, scientists have shown that they can send light through “slits in time” in time. The new experiment is a twist on a 220-year-old demonstration, in which light shines through two slits in a ...

Anomalous bunching effect in which all photons coalesce into two output beams,. Credit: Ursula Cardenas Mamani A counterintuitive facet of the physics of photon interference has been uncovered by ...

By Kat Troche September 2025 marks ten years since the first direct detection of gravitational waves as predicted by Albert ...

Can we turn back time? Ask a savvy physicist, and the answer will be “it depends.” Schemes for retrograde time travel abound but usually involve irreconcilable paradoxes and rely on outlandish ...

The famous double-slit experiment, which demonstrated that light is both a wave and a particle, has been performed using “slits in time”. The techniques involved present a new way to manipulate light ...

Interference from human activity has always been a sticking point in astronomical observations. Radio astronomy is ...

Researchers replicated the classic double slit experiment using lasers, but their slits are in time not space. When you purchase through links on our site, we may earn an affiliate commission. Here’s ...
