Daily Discussion: How would you explain the essence of time to a three year old?

This is a question a friend asked recently, and while she was looking for a much more practical answer, like using a wooden clock to teach the long hand and short hand, it made me wonder how you would try to explain something like “What is time?” to a three year old? It’s a question that isn’t clearly understood at even the deepest levels of physics… we know time is a real thing, but we don’t know exactly what it is, and yet how would you explain to a three year old the very essence of time stretching across the universe and back?

Using temporal cloaking to hide data transfer

In the past several years, there have been advancements in developing visual cloaking devices that bend light around an object to make it appear invisible. But even cooler is when you can hide something in time, or temporal cloaking. Such a sci-fi feat is now possible in the field of data transfer— scientists have been able to hide data in a beam of light, hidden in time itself to make it appear to have never existed.

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."

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.
