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 ...

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 ...

Does the universe notice that we're paying attention to a quantum experiment? The answer goes against everything we thought we knew.

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 ...

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, ...

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 ...

There is a glaring gap in our knowledge of the physical world: none of our well-established theories describe gravity’s quantum nature. Yet physicists expect that this quantum nature is essential for ...

Scientists are planning on 'dimming the Sun' in a bid to curb global warming. The UK government is set to announce funding of up to £50m of funding for Sun-dimming experiments in the coming weeks, the ...

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 ...
