The constancy of the speed of light is a pillar of modern physics, but questions persist about its absolute universality.

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 ...

Addressing a controversy first raised around 1910, two physicists have performed experiments with the aid of an engineer that validate anew the special theory of relativity’s limitations on the speed ...

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 ...

LIVERMORE, Calif. — Scientists have successfully observed the transformation of neutrinos – a particle that is relatively massless, has no electric charge, yet is fundamental to the structure of the ...

Physicists have taken quantum strangeness to an extraordinary new level by measuring light across 37 dimensions. Their groundbreaking experiment pushes quantum mechanics beyond classical expectations, ...

From a telescope network that spans much of the globe to a psychology study that spans 67 countries, here are the biggest science experiments on the planet. When you purchase through links on our site ...

Much of what we know about plant circadian rhythms is the result of laboratory experiments where inputs such as light and temperature can be tightly controlled. Less is known about how these ...

Physicists using near-absolute-zero detectors have reached unprecedented sensitivity in the hunt for light dark matter. A ...

Sometimes science needs to go big. From telescopes spanning the globe to particle accelerators that would take over 24 hours ...
