A recent experiment shows how quantum mechanics can make heat flow from a cold body to a hot one, an apparent (though not real) violation of the second law of thermodynamics.
The renowned British physicist, who died at 76, left behind a riddle that could eventually lead his successors to the theory of quantum gravity.
A recently proposed experiment would confirm that gravity is a quantum force.
Physicists are trying to rewrite the axioms of quantum theory from scratch in an effort to understand what it all means. The problem? They’ve been almost too successful.
Time isn’t just another dimension, argues Tim Maudlin. To make his case, he’s had to reinvent geometry.
A simple analogue could offer insights into one of the most astonishing results of quantum mechanics.
A new class of quantum particle is about to emerge from the tangled considerations of quantum statistics.
Can balloon animals help blunt uneasy feelings about “spooky action at a distance”?
Physicists are closing the door on an intriguing loophole around the quantum phenomenon Einstein called “spooky action at a distance.”
