Time is not absolute, with gravity and velocity affecting how fast it passes, making clocks at different heights or near ...
Scientists have discovered that dark matter, the universe's most mysterious "stuff," obeys gravity on vast cosmological ...
The world's most sensitive table-top interferometric system—a miniature version of miles-long gravitational-wave detectors like LIGO—has completed its first science run. The Quantum Enhanced ...
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 ...
“You can’t beat the view,” astronaut George Clooney says to NASA scientist Sandra Bullock as they gaze from their space station at the Earth, 372 miles below. Gravity enjoyed a similarly lofty view ...
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.
