It may sound less likely than hell freezing over, but physicists have created an atomic gas with a sub-absolute-zero temperature for the first time1. Their technique opens the door to generating negative-Kelvin materials and new quantum devices, and it could even help to solve a cosmological mystery

If built, such systems would behave in strange ways, says Achim Rosch, a theoretical physicist at the University of Cologne in Germany, who proposed the technique used by Schneider and his team3. For instance, Rosch and his colleagues have calculated that whereas clouds of atoms would normally be pulled downwards by gravity, if part of the cloud is at a negative absolute temperature, some atoms will move upwards, apparently defying gravity

This just blew my mind.

although I'd prefer they call it "anti-energy". Dark energy sounds like sorcery.

You say floating skateboards, I say fusion reactors.

So we can now build quantum torpedos and quantum slipstream drives? Sign me up. :)

I'd spread that poo all over my yard in the fall to keep the leaves off.
