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?

You can say the universe has a split personality. Or better said, our physical models of the universe are the ones fractured. On the grand scale of stars and galaxies, gravity rules. Albert Einstein’s ...

Cold atom experiments are among the most powerful and precise ways of investigating and measuring the Universe and exploring the quantum world. By trapping atoms and exploiting their quantum ...

Quantum technologies promise powerful new kinds of computers, giving scientists new tools to mimic and explore nature at its tiniest scales. At those levels, everything in nature—from atoms and ...

As physicists search for a theory of quantum gravity, new results show that classical gravity can still interact with quantum fields to allow matter to become entangled. When you purchase through ...

Quantum physicists have uncovered a bizarre phenomenon in which photons appear to spend a “negative” amount of time ...

Scientists have directly watched angular momentum move through a crystal for the very first time — and discovered a bizarre ...

Scientists have pulled off a mind-bending quantum experiment that sounds almost impossible: they showed that tiny metal particles made of thousands of atoms can exist in multiple places at once. Using ...

Perfect randomness sounds simple, until you try to make it. A die can be polished, balanced and rolled thousands of times.

Can a small lump of metal be in a quantum state that extends over distant locations? A research team at the University of Vienna answers this question with a resounding yes. In the journal Nature, ...

Some researchers believe consciousness is a byproduct of the constantly firing web of neurons in our heads. However, others believe something more theoretical must be involved to explain our complex ...
