3. But the best thing is that they don't have to actually create neutron degenerate matter itself, just cool some lithium-6 gas to nearly absolute zero, grab it inside a laser trap and make it wobble.

- absolute zero (n.) "lowest possible temperature which the nature of heat admits" (determined to be –273 centigrade, –458 Fahrenheit), the idea dates back to 1702 and its general value was guessed to within a few degrees soon thereafter, but not precisely discovered until Lord Kelvin's work in 1848. It was known by many names, such as infinite cold, absolute cold, natural zero of temperature; the term absolute zero was among them by 1806.
