A closed door feels absolute. Light stays in one room, darkness settles in the next, and the boundary seems obvious enough to stop thinking about. Yet the same wall that blocks the glow from your ...

Cutting-edge atomic clocks may soon reveal a strange possibility: time itself behaving like a quantum object, existing in ...

New multiscale simulations help crack long-standing mysteries behind the enormous radio arcs generated when galaxy clusters collide. When you purchase through links on our site, we may earn an ...

Scientists in Japan have uncovered a strange new behavior in “heavy” electrons — particles that act as if they carry far more mass than usual. These electrons were found to be entangled, sharing a ...

A neglected force produced by neutrinos and other particles helps atomic physics measurements align with predictions of the standard model.

From reverse waterfalls to gravity-defying hills, some places on Earth seem to challenge physics. These strange spots attract ...

Physicist Lisa Randall believes an extra dimension may exist close to our familiar reality, hidden except for a bizarre sapping of the strength of gravity as we see it. Boston Globe via Getty Images ...
