Quantum mechanics and relativity are the two pillars of modern physics. However, for over a century, their treatment of space ...

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

A new theory of quantum gravity, which attempts to unite quantum physics with Einstein's relativity, could help solve the puzzle of the universe's expansion, a theoretical paper suggests. When you ...

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

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.

Physicists have long treated space and time as the stage on which quantum particles perform, not as actors in the drama ...

The nature of quantum entanglement remains an outstanding problem in physics. But Albert Einstein's theories, along with insights from quantum computing, could finally put the mystery to rest. When ...

The original version of this story appeared in Quanta Magazine. Two blind spots torture physicists: the birth of the universe and the center of a black hole. The former may feel like a moment in time ...

Two landmark quantum experiments have sharpened one of the oldest arguments in modern physics, and the verdict is not kind to ...
