Quantum gas below absolute zero: dark energy?

Another peculiarity of the sub-absolute-zero gas is that it mimics 'dark energy', the mysterious force that pushes the Universe to expand at an ever-faster rate against the inward pull of gravity.

I won't pretend to fully understand it, but I understood enough to say:

Gotta love the comments on that article!

I don't know anything about commenting, but I think you are right.
Correct me if I'm wrong.

[Umfriend]

[Elie]

Am I right in saying you are all wrong?

Please correct me if I am right

[Fat Tone]

That's just plain wrong, right?

Only when the quantum gas particles generate a negative temperature which alters the fabric of the space time contimuum due to its caustic anti-matter interaction with real space-time, which causes right to be wrong, up to be down, black to be white, and zebra crossings to become very dangerous.
