Quantum physics is the realm of the strange. And one of the strangest discoveries in the field is also one of the most fundamental: Particles fired at barriers with two slits in them can act like ...

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 ...

And an international team of physicists appears to have found just such a loophole: the only thing that goes faster than ...

Physicists have experimentally confirmed a strange prediction: the dark “holes” inside light waves can appear to move faster ...

The following is an extract from our Lost in Space-Time newsletter. Each month, we dive into fascinating ideas from around the universe. You can sign up for Lost in Space-Time here. When physicist ...

Here’s what you’ll learn when you read this story: Although people often say nothing travels faster than the speed of light, this cosmic speed limit only pertains to particles with information or mass ...

A theoretical study accepted by Physical Review Letters predicts that gravitational waves, the faint ripples in spacetime produced by colliding black holes and neutron stars, can leave detectable ...

NEW YORK, March 13, 2023 — When we look in a mirror, we are used to seeing our faces looking back at us. The reflected images are produced by electromagnetic light waves bouncing off of the mirrored ...
