Most of us have experienced the frustration of seeing a film on the computer hacked into different still images because the computer couldn't process the information fast enough to give us a fluid picture of the movie. Once the computer gets up to speed — that speed being twenty-four images flashed at us for every second we're watching — we see motion, not pictures. Sped up a little faster, and we'd still see motion, not pictures. We wouldn't be able to distinguish between one and the other. That is the limit of our temporal resolution, or the number of times our mind and eyes can 'update' the picture we're seeing. More »

For decades, the world has relied on incredibly accurate atomic clocks to keep time; but atomic clocks are much more consistant than the rotation of the Earth, which varies in speed ever-so-slightly as it spins about its axis. Consequently, every few years, the time based on the Earth's rotation falls out of sync with time kept by atomic clocks. More »

We all know that time has direction, because we've all experienced it; you will never again be as young, for example, as you are at this very second. Or this second. Or this second. The directionality of time prohibits it. More »

Back in the days before satellites beaming the time at our phones, finding the correct time was a challenge. Once the Industrial Revolution turned each hour into a billable hour, it was necessary to standardize time across a whole city. Enter Ruth Belville, a real-life Time, ah, Lady, who kept London on schedule. More »

With Valve's breakout video games, Portal and Portal 2, attracting so much attention as of late, it's easy to forget that portals are something of a time-honored tradition in science fiction and fantasy. So, in the spirit of inclusiveness, we've reached outside the orange box to bring you this collection of concept art, fan art, and stills from some of our favorite windows in time and space. More »

Are we living out the results of a temporal conspiracy in which hundreds of years were smuggled into the Roman calendar to convince us that the Middle Ages happened? Are we really living in the 1700s? This chart explains. More »

A crucial goal for the Large Hadron Collider is to find the long-sought Higgs boson. It might also create another Higgs particle that only travels through hidden dimensions, meaning it can pop in and out of any point in time. More »

Quantum entanglement says that two particles can become intertwined so that they always share the same properties, even if they're separated in space. Now it seems particles can be entangled in time, too. Who's ready for some serious quantum weirdness? More »

There is a force called "dark flow" that exists outside our universe, and it's tugging several galaxy clusters at 2 million mph toward an empty spot in space between Centaurus (pictured) and Vela. This isn't like dark matter, which exerts a more localized pull: Dark flow is a force that's operating at a universe level to push enormous chunks of matter around. Writing in Astrophysical Journal Letters, a group of astronomers say that this dark flow comes from a place where constants like time don't exist — nor do stars and galaxies. More »
