Physics is supposed to be predictable. Drop a ball, and gravity pulls it down. Heat water, and it boils. Light travels in straight lines. Yet throughout history, scientists have encountered ...

Physics experiments have changed the world irrevocably, altering our reality and enabling us to take gigantic leaps in technology. From ancient times to now, here's a look at some of the greatest ...

Imperial physicists have recreated the famous double-slit experiment, which showed light behaving as particles and a wave, in time rather than space. The experiment relies on materials that can change ...

In day-to-day life, light seems intangible. We walk through it and create and extinguish it with the flip of a switch. But, like matter, light actually carries a little punch—it has momentum. Light ...

The most beautiful experiment in physics, according to a poll of Physics World readers, is the interference of single electrons in a Young’s double slit. Robert P Crease reports Simply beautiful – the ...

Scientists have discovered “unexpected physics” by opening up “slits” in time, a new study reports, achieving a longstanding dream that can help to probe the behavior of light and pioneer advanced ...

Quantum physicists have measured negative time in a remarkable quantum experiment that is reshaping discussions around quantum mechanics, photon behavior, and the nature of time itself. The study, ...

Anne L’Huillier of Lund University, Pierre Agostini of The Ohio State University, and Ferenc Krausz of the Max Planck Institute of Quantum Optics won this year’s Nobel Prize in Physics “for ...

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 ...

The process that powers much of life on Earth, photosynthesis, is so finely tuned that just one photon is enough to kick it off. Scientists have long suspected that photosynthesis must be sensitive to ...
