In a groundbreaking discovery, physicists have for the first time observed individual free-range atoms interacting in free space, confirming a quantum mechanical theory proposed over a century ago.

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 ...

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 ...

The problem with quantum mechanics, or at least the reason even physicists don’t understand it, isn’t that it paints an unfamiliar picture of reality. It isn’t difficult to accept that the world of ...

Just over 200 years after French engineer and physicist Sadi Carnot formulated the second law of thermodynamics, an international team of researchers has unveiled an analogous law for the quantum ...

Physicists claim they may have found a long-awaited explanation for dark energy, the mysterious force that's driving the accelerated expansion of the universe, a new preprint study hints. Their ...
