The squeaking of sneakers on a gym floor is usually attributed to friction, specifically a stick-slip variety that involves cycles of sticking and sliding between two surfaces. But that model is best ...

A study published in Nature Ecology and Evolution on February 24, 2026, confirms that animals experience time at speeds dictated by their metabolic rates and ecological demands, with small, ...

I explore how the speed of light could be visualized here on Earth in a fun experiment.

Back in 2000, a team of physicists led by Lijun Wang at the NEC Research Institute in Princeton, USA, pulled off a mind-bending experiment. They fired a precisely shaped laser pulse through a special ...

Immediately after the Big Bang boomed, the Universe was a trillion-degree ' soup ' of unimaginably dense plasma. In a ...

A beam of light weaker than the bulb inside a refrigerator has delivered internet speed data from a satellite more than ...

In physics, to qualify as another reality means it must lie beyond the four known space-time dimensions. Such a realm must also be inaccessible, like public restrooms in the Big Apple. Good examples, ...

Casimir cavities are mysterious spaces between microscopic metal plates in a vacuum. Areas of diminished energy between the plates cause them to push toward each other, as if trying to fill the ...

Cisco Systems and startup Qunnect said on Wednesday that they have built and operated a quantum network between Brooklyn and Manhattan in New York which sends signals over real-world fiber optic ...

Adjusting the size and chemistry of nanocrystals within an ultrathin surface can speed up light-driven chemical reactions, ...

Physicists artificially slowed down time to reveal the bizarre Terrell-Penrose effect, a consequence of special relativity. This image from the experiment shows a sphere seemingly moving at 99.9 ...
