How You Can Get Temperatures Below Absolute Zero

It used to be that scientists all agreed that it was impossible to achieve temperatures below absolute zero, but now they realise that’s not entirely true. This video explains how you can reach temperatures below absolute zero.

How Iron Man's Arc Reactor (Probably) Works

Since the Iron Man arc reactor is a fictitious device, and it has no official scientific explanation in the Iron Man canon that I’m aware of, we might as well something up. Now, I’m mixing real science and fake science here. So physics nerds and comic-book nerds: Deal with it.

Why We Should Keep Trying To Time Travel

H.G. Wells coined the term “time machine” all the way back in 1895, just a decade before Einstein published his groundbreaking paper on special relativity that would begin show how time travel is possible. The fascination with using technology to look into the past or the future hasn’t faded in the last century. And as the thought experiment endures, you have to wonder: When will we finally do it — and why?

How Do We Make Transforming Quantum Circuits? Lasers And Ultracold Atoms

Well, here’s a cooooool finding. Take any piece of electronic equipment you can think of and its circuits are powered by, yes, electrons. But a new experiment takes us one step closer to “atomtronic circuits” made of supercold quantum matter that can be reconfigured on the fly.

You Can Make Diamonds Out Of Peanut Butter

Diamonds are beautiful, but, sadly, they’re rather expensive. Now, Dan Frost of the Bayerisches Geoinstitut in Germany has discovered that you can make them from peanut butter. No, really.

A Radically New Particle Accelerator Could Have 500 Times The Power

If you know anything about the Large Hadron Collider, you know that it is huge. Massive. 17 miles of tunnels under Switzerland. Traditional accelerators need all that space to get particles to smash into each other at close to the speed of light. But scientists at Stanford have come one step closer to a new type of particle accelerator that could do the same at just a fraction of the size.

Yes, Time Travel Is Possible; Here's How

Time travel’s been one of man’s wildest fantasies for centuries. It’s long been a popular trend in movies and fiction, inspiring everything from Charles Dickens’ A Christmas Carol to H.G. Wells’ The Time Machine to the Charlton Heston shrine that is The Planet of the Apes. And with the opening of Interstellar today — not to spoil anything — we’re about to fantasize about it even more.

Can You Help CERN Identify What's Happening In These Archive Images?

As an institute full of scientists, you might think CERN was good at keeping records. But it’s happened upon a stash of archived images that seem to make no sense whatsoever — and it wants you to help it work out what they show.

This Is What Happens In Slow-Mo When You Shoot Liquid Drops With Lasers

Lasers? Fun. Slow motion? Beautiful. Shooting things with lasers and recording what happens in slow motion? That will be what happens in this beautiful video.

Monster Machines: Scientists Are Creating The Coldest Cubic Metre In The Universe

It’s hard to describe exactly how cold the coldest cubic metre in the universe will be. Frozen to just a blip above absolute zero — the temperature at which atoms cannot even vibrate — the CUORE experiment will try to nail down a tiny number that has long eluded physicists: the mass of a neutrino.
