Physicists have developed a novel approach to solving one of the most persistent problems in theoretical physics: uniting gravity with the quantum world. In a recent paper published in the journal ...

"We have long treated the Planck scale like a blurry limit," said Kulkarni. "But if you treat space as an information storage medium, geometry dictates a specific packing efficiency. The universe has ...

For nearly a century, some of the simplest questions in quantum theory have stubbornly resisted clean answers, turning basic ...

Scientists test Einstein’s quantum challenge with one atom, directly measuring when photon paths erase interference stripes.

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

On 9 July 1925, Heisenberg sent a paper titled ‘Quantum-theoretical re-interpretation of kinematic and mechanical relations’ to Max Born, whom he was assisting at that time, and Born sent the paper to ...

As Joe Howlett points out, "the Schrödinger equation remains physicists’ foremost window into the quantum realm. It tells scientists how that strange world works; that is, how quantum objects interact ...

“This retroactive idea. It has to be that,” says Nobel Prize-winning mathematical physicist Sir Roger Penrose, reflecting on a problem about the building blocks of reality that has dogged physics for ...

The notion that quantum reality is your reality looms as a rich and enticing possibility. Until very recently, the very prospect was all but unthinkable, however. In everyday life there appears to be ...

Physicists long believed time was a basic feature of the universe. But it may just emerge from cosmic information.

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.
