A newly derived “q-desic” equation suggests that quantum effects may subtly alter particle trajectories across the universe.

Austrian physicist Erwin Schrödinger developed quantum theory’s wave equation, which describes quantum systems as waves that ...

The MarketWatch News Department was not involved in the creation of this content. CALABASAS, Calif., Feb. 9, 2026 /PRNewswire/ -- A new theoretical framework released today proposes that the vacuum of ...

The mysterious quantum universe questions our conventional understanding of reality. In this reality, particles can exist in several states at once, be entangled across great distances, and where the ...

I keep coming back to a strange idea: what if everything we know about quantum physics is already encoded inside a single atom? Not in a mystical sense, but in the very real way that one tiny system ...

Physicists have long struggled to unite quantum mechanics—the theory governing tiny particles—with Einstein’s theory of ...

A radical idea that resolves many quantum paradoxes suggests there is no objective view of reality. How can the cosmos be ...

Quantum mechanics is one of the most successful theories in science — and makes much of modern life possible. Technologies ranging from computer chips to medical-imaging machines rely on the ...

According to a new theory, our universe developed from a “pre-inflationary multiverse” made of particles in quantum superposition.

More than a century before quantum mechanics was born, Irish mathematician William Rowan Hamilton stumbled onto an idea that ...

But after reading Decoherence and Quantum Darwinism, a book published in March 2025 by the physicist Wojciech Zurek, I’m excited by the possibility of an answer that does away with all those fanciful ...

Over 85 years after it began, the Einstein-Bohr debate remains the most consequential intellectual rivalry in modern science ...
