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?

A team of physicists has reimagined one of science’s most iconic experiments—but in the dimension of time. Researchers at Imperial College London have taken the classic double-slit test and turned it ...

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 ...

(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 ...

Two landmark quantum experiments have sharpened one of the oldest arguments in modern physics, and the verdict is not kind to Albert Einstein’s instincts about reality. By stripping classic thought ...

Thanks to advances in science, we’re now able to move beyond Bohm and Bohr’s theorizing; we can test their hypotheses through ...
