Quantum mechanics and relativity are the two pillars of modern physics. However, for over a century, their treatment of space ...

Quantum theory and Einstein's theory of general relativity are two of the greatest successes in modern physics. Each works ...

This interaction could help explain both why quantum processes can occur within environments like the brain and why we lose ...

This year is the International Year of Quantum Science and Technology, according to UNESCO, marking 100 years since quantum mechanics was proposed. The theory hardly needed the extra publicity, though ...

A new physics paper takes a step toward creating a long-sought "theory of everything" by uniting gravity with the quantum world. However, the new theory remains far from being proven observationally.

Physicists are quietly rewriting the rulebook for how we might cross the gulf between stars, not by bolting bigger rockets to launch pads but by probing the strange limits of quantum theory. A new ...

We’re celebrating 180 years of Scientific American. Explore our legacy of discovery and look ahead to the future. This year is the International Year of Quantum Science and Technology, according to ...

Forgetting feels like a failure of attention, but physics treats it as a fundamental process with a measurable price. At the ...

The ball rolls across the floor because it was kicked, just as Earth orbits the sun because it is tugged by gravity. The connection between cause and effect is fundamental to how we understand the ...

An international collaboration sheds new light on the relationship between quantum theory and thermodynamics. The research group demonstrated that while the laws of quantum theory alone do not ...
