Proposed four dimensional crystal clock could theoretically outlast the universe itself
The problem with thinking about the improbability of a perpetual motion machine is that regardless of how clever you think you are, forever is forever, meaning even our own universe will one day, a long time from now, completely run out of energy and will die. This situation is known as the heat death of the universe, and at that point, nothing will be left. Except perhaps this clock…

Scientists posit theory that at some point, all time could just stop
It’s the current accepted wisdom that the universe is expanding and expanding, and at one point, it might all just drift apart or it could contract into a singularity again. Or, as an alternate theory, at some point, billions and billions of years from now, time could eventually come to a stop and everything just freezes in place forever.

Minute physics: “How long is a second?”
The moon may be 1.3 light-seconds away, but why on earth do we measure distances using time?

What’s the difference between the past and future?
Why is the past different from the future? Caltech physicist Sean Carroll explains how the arrow of time is not an intrinsic property of physics, but rather an emergent feature.

Mind-bending reading material: “An Experiment With Time” by JD Dunne, 1927
In 1927, an Irish aeronautical engineer named JW Dunne wrote one of the most influential and controversial books that you’ve probably never heard of called An Experiment With Time.

So this is what the end of time looks like
Since it’s highly unlikely that you’ll be around to see the end of time, so a pair of physicists have simulated what the end of time would look like using the magic of metamaterials.

Update: Time cloaking is real and it’s pretty wicked
Last week, there was an article on IHC from November of last year on how temporal cloaking was very possible and recently, a team at Cornell university actually fucking did it— they created a temporal cloak and a hole in time itself. Fuck.
Space time cloak could hide events in the folds of time
“If you had someone moving along the corridor, it would appear to a distant observer as if they had relocated instantaneously, creating the illusion of a Star Trek transporter,” says McCall. “So, theoretically, this person might be able to do something and you wouldn’t notice.”
Carl Sagan explains time dilation
You may already understand time dilation, but everything is better with Carl Sagan.

Could the Large Hadron Collider be the world’s first time machine?
Physicists at Vanderbilt University have proposed a theory that the Large Hadron Collider could be the first machine capable of causing matter to travel backwards in time, says professor Tom Weiler.
DON’T DO IT.

How to measure one year on Earth
Seems simple enough, right? Just pick a starting point in the orbit and when the Earth returns to that point, we’ve completed a year. Done. Well… not so much. The problem is that the Earth doesn’t go along the exact same path every year.

Scientists measure the shortest amount of time ever
Proving your girlfriend wrong, there is a shorter amount of time than “Was that it?” Scientists in Germany decided to hit electrons with light and then measure how quickly they moved. The result was 20 attoseconds, the shortest period of time ever measured. One attosecond is one quintillionth of a second.

Is time slowly disappearing from the universe?
We always use the term “running out of time” for all sorts of things in our daily lives, and Jack Bauer was always running out of time, but we’ve generally accepted that time is something that’s constant and will always be around literally forever and ever. Except a couple of guys from Spain seem to think that time will run out some day. Shit. I’d better get on that to-do list.
