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 ...

Our universe plays by certain rules, which originate from different branches of physics. But sometimes the rules seem ...

Quantum entanglement can link two objects even when they are separated by extremely large distances. But a new study has found a limit at which such quantum correlations stop – and surprisingly, ...

This episode of the Physics World Weekly podcast features Alex May, whose research explores the intersection of quantum ...

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

For more than a century, the double-slit experiment has been the sharpest test of what reality is made of, and of whether ...

An international team of physicists has proven new theorems in quantum mechanics that describe the 'energy landscapes' of collections of quantum particles. Their work addresses decades-old questions, ...

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.

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 ...

Suppose you’re a CIO or senior application planner, and you need to understand whether you should dig into quantum computing ...

You might say it all started with a spot of hay fever. In June 1925, a young physicist named Werner Heisenberg retreated to the barren island of Helgoland in the North Sea, seeking respite from his ...
