(via PBS Space Time) We know that gravity must cause clocks to run slow on the basis of logical consistency. And we know that gravity DOES cause clocks to run slow based on many brilliant experiments.

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 ...

The Universe, as we know it, has a fundamental flaw staring us right in our faces, letting us know that our knowledge is incomplete. The four fundamental forces are described by two different and ...

Gravitational waves may leave a permanent timing gap in light, revealing how gravity preserves information through a memory ...

Most lovers of science fiction are quick to tell you that there's a "time-honored" (pun intended) way to build a time machine - somehow get a wormhole and use it as a bridge to travel through time.

We first discovered the laws of gravity, and then those of quantum mechanics. But new work suggests nature might go about it the other way around: space-time, and hence gravity, could emerge from a ...
