In the late 1970s, legendary physicist John Wheeler proposed a radical question: Exactly when does the universe notice that we're paying attention to a quantum experiment? And does it really matter?

(via Sabine Hossenfelder) The double-slit experiment is a famous quantum physics experiment that shows that light exhibits behavior of both a particle and a wave. In a new paper, researchers claim ...

A groundbreaking quantum experiment conducted by MIT physicists has turned a major page in the long-standing debate between Albert Einstein and Niels Bohr. Their recent work, published in Physical ...

Physicists confirm that light has two identities that are impossible to see at once. (Nanowerk News) MIT physicists have performed an idealized version of one of the most famous experiments in quantum ...

Physicists at MIT recreated the double-slit experiment using individual photons and atoms held in laser light, uncovering the true limits of light’s wave–particle duality. Their results proved ...

The famous double-slit experiment, which first demonstrated light behaving like both particles and a wave, has been recreated by physicists who now say they have achieved it in time rather than in ...

James is a published author with multiple pop-history and science books to his name. He specializes in history, space, strange science, and anything out of the ordinary.View full profile James is a ...

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 ...

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 ...

Schematic of the MIT experiment: Two single atoms floating in a vacuum chamber are illuminated by a laser beam and act as the two slits. The interference of the scattered light is recorded with a ...
