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 ...

"These single atoms are like the smallest slits you could possibly build." For over 100 years, quantum physics has taught us that light is both a wave and a particle. Now, researchers at the ...

Reconfigurable intelligent surfaces (RIS) are engineered structures comprised of several elements known as 'meta-atoms,' ...

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 ...

Researchers have developed a thin film device, fabricated by spray coating, that can block electromagnetic radiation with the flip of a switch. The breakthrough, enabled by versatile two-dimensional ...

Does light behave more like a particle, or like a wave? Today we know the surprising answer. Here's why it took so long to get there. When you purchase through links on our site, we may earn an ...

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 ...

A recent discovery by materials science researchers in Drexel University’s College of Engineering might one day prevent electronic devices and components from going haywire when they’re too close to ...

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 ...
