Once a baffling theory, quantum mechanics has evolved into a driving force behind modern technology and frontier research.

Quantum theory explains the behavior of matter and energy at the smallest scales, like atoms and subatomic particles. Unlike ...

Quantum theory and Einstein's theory of general relativity are two of the greatest successes in modern physics. Each works extremely well in its own domain: Quantum theory explains how atoms and ...

Quantum theory is often sold as a story about tiny particles, but its real disruption lands squarely on our everyday sense of what is real. At the smallest scales, the equations that power lasers, ...

Some quantum cryptographers want to find ways to keep messages secret even if the rules of quantum mechanics don’t hold. The ...

Causal Set Theory (CST) offers a compelling approach to reconciling quantum theory and general relativity by postulating that spacetime, at its most fundamental level, is discrete rather than ...

Add Yahoo as a preferred source to see more of our stories on Google. Quantum mechanics is both the most powerful theory physicists have ever devised and the most baffling. On the one hand, countless ...

Before Einstein, before Bohr, there was a Jesuit priest with a telescope and a startlingly modern vision of the universe.

If you asked a thousand physicists, they would all disagree. This statement could apply to any number of topics – whether the universe is infinite, what dark matter is made of, how to make wires ...

Quantum mechanics is both the most powerful theory physicists have ever devised and the most baffling. On the one hand, countless experiments have confirmed its predictions; the theory undergirds ...
