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

A thought experiment that was at the heart of an argument between famed physicists Albert Einstein and Niels Bohr in 1927 has finally been made real. Its findings elucidate one of the core mysteries ...

Scientists have made leaps and bounds in bending atoms to their will, making them into everything from ultraprecise clocks to ...

As strange and unique as the laws of the quantum realm appear in our everyday experience, every now and then experiments catch sight of phenomena that seem both alien and yet eerily familiar. For the ...

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 ...

Learning how a physical system behaves usually means repeating measurements and using statistics to uncover patterns. That ...

Scientists are using anesthesia to probe the quantum roots of consciousness—and the research offers tantalizing evidence.

A team of researchers at University of Science and Technology of China (USTC) has reconstructed one of Albert Einstein’s most famous attempts to poke holes in quantum theory, and the results land ...

A paradox at the heart of quantum physics has been tested in an extraordinary fashion, pushing the boundaries of human intuition beyond breaking point by measuring a pulse of light in 37 dimensions.

A real mind-melter: Quantum mechanics is strange, but even for a field of science that regularly defies our conventional understanding of reality, the latest discovery is particularly baffling.

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 ...

Physicists seem to be obsessed with cats. James Clerk Maxwell, the father of electrodynamics, studied falling feline s to investigate how they turned as they fell. Many physics teachers have used a ...
