The quantum revolution in physics — whose 100th anniversary we have just celebrated — taught us that at the most basic level ...

Physicists have long treated space and time as the stage on which quantum particles perform, not as actors in the drama themselves. A new theoretical framework now flips that script, treating space ...

A photon enters an extraordinarily intense laser field. When it exits, its polarization has rotated, as though empty space ...

Quantum mechanics and relativity are the two pillars of modern physics. However, for over a century, their treatment of space and time has remained fundamentally disconnected. Relativity unifies space ...

Physicists have shown how time can effectively be reversed for some quantum systems, which would allow for new ways to ...

Add Yahoo as a preferred source to see more of our stories on Google. For close to a century, scientists have been trying to marry Albert Einstein’s General Theory of Relativity and quantum theory—our ...

Astrid Eichhorn spends her days thinking about how the laws of physics change at the tiniest scales. Imagine zooming in closer and closer to the device on which you’re reading this article. Its ...

Einstein, Juan Maldacena, Mark Van Raamsdonk, Brian Swingle and other physicists have pushed modern physics into a place ...

As physicists search for a theory of quantum gravity, new results show that classical gravity can still interact with quantum fields to allow matter to become entangled. When you purchase through ...
