If true, the idea would blow past one of physics’ most sacred limits: that parallel versions of reality can never talk to ...

Cosmology and quantum physics both offer tantalizing possibilities that we inhabit just one reality among many. But testing that idea is challenging.

Picture Victorian London, but its skies are filled with airships. Steam-powered robots crowd the streets, mingling with people in top hats and petticoats. That type of retrofuturistic mash-up is the ...

The properties of a quantum material are driven by links between its electrons known as quantum correlations. A RIKEN ...

An old puzzle in particle physics has been solved: How can quantum field theories be best formulated on a lattice to ...

Einstein and the Quantum Revolutions Alain Aspect Univ. Chicago Press (2024) French physicist Alain Aspect is a pioneer in ‘quantum entanglement’ — connections between the quantum properties of ...

Time feels steady and familiar in daily life, but at the quantum level it becomes slippery. That puzzle now has a fresh twist ...

It is something like the "Holy Grail" of physics: unifying particle physics and gravitation. The world of tiny particles is described extremely well by quantum theory, while the world of gravitation ...

Here’s what you’ll learn in this story: The measurement problem in quantum mechanics looks at how an experimental outcome changes, simply by observing it. While most physicists agree that human ...

I like to go running in my free time. I’m not an especially fast jogger, but I think I could keep up with a tortoise. According to Zeno of Elea, an ancient Greek scholar who lived around 450 B.C.E., ...

Technological devices are getting ever smaller, but as they approach the scale at which quantum physics matters, our understanding of how they interact with their environment evaporates. James Millen ...
