Several weeks ago I picked up “The Elegant Universe” because I thought it would have information on The Ultimate Theory. Soon afterwards, I picked up “How to Teach Physics To Your Dog” in order to get ...

Can a photon be caught behaving like a wave and a particle in the same run of an experiment? For almost a century, that question sat at the heart of a famous disagreement between Albert Einstein and ...

Physicists and Marvel aficionados worldwide are intrigued by multiverse theory. A new study provides a major challenge to this theory, stated Earth. The examination is based on a photon. Findings ...

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?

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 ...

Researchers demonstrate that some forms of quantum behavior can only occur via pairwise interactions, a finding that limits the number of ways in which we can reconcile quantum mechanics with ...

Most of us have heard about the double-slit experiment being performed using photons or electrons, but what about atoms and molecules? Prepare to have your mind boggled! Most of us have heard about ...

Strength in weakness: physicists in 2011 gained information about the paths of photons in a double-slit experiment without destorying interference. (CC BY Timm Weitkampf) By studying how photons ...
