Astronomers have just made a new measurement of the Hubble Constant, the rate at which the universe is expanding, and it doesn’t quite line up with a different estimate of the same number. That ...

The flow of time isn’t as consistent as we might think – gravity slows it down, so clocks on the surface of Earth tick slower than those in space. Now researchers have measured time passing at ...

Pittsburgh Physicists Expose Flaw in How Quantum Breakthroughs Are Claimed In A Nutshell The solution: share complete ...

In a dual set of papers published in Science last week, an international group of researchers presented an experiment which used relativistic time dilation to measure the curvature of spacetime. The ...

Forgetting feels like a failure of attention, but physics treats it as a fundamental process with a measurable price. At the ...

Biology has always been an unruly science. Cells divide when they want to. Genes switch on and off like temperamental lights.
