Scientists are testing a novel way to measure cosmic expansion using time delays in gravitationally lensed quasars. Their ...

The geometry of space, the setting in which physical laws operate, may hold clues to some of the biggest unanswered questions in fundamental physics. The underlying structure of spacetime itself could ...

For more than a century, physicists have suspected that the familiar three dimensions of space might be only a small slice of ...

Time, not space plus time, might be the single fundamental property in which all physical phenomena occur, according to a new theory by a University of Alaska Fairbanks scientist. The theory also ...

Observers moving faster than the speed of light would see a universe with one dimension of space and three dimensions of time — the opposite of how we perceive the world. This is the bizarre ...

It is believed that matter, motion, gravity, and everything else we know of originated from the three dimensions of space and one of time. However, a new idea challenges this theory, suggesting that ...

Linear measurement tools are essential for determining the dimensions of an object. These tools provide a way to quantify distance in a straight line. In engineering and physics, getting your ...

Are entangled particles connected via another dimension, since they continue to be connected and a reflection of each other regardless of distance? originally appeared on Quora: the place to gain and ...

Quantum mechanics is an outstandingly successful description of nature, underpinning fields from biology through chemistry to physics. At its heart is the quantum wavefunction, the central tool for ...

The laws of physics stay the same no matter one’s perspective. Now this idea is allowing computers to detect features in curved and higher-dimensional space. Computers can now drive cars, beat world ...
