Examples

  • A stellar black hole of 10 solar masses, for example, would have a Hawking temperature of several nanokelvin, much less than the 2. 7K produced by the Cosmic Microwave Background.

  • This corresponds to temperatures of the order of 100 nK (nanokelvin), i.e. a tenth of a millionth of a degree above absolute zero.

  • Cornell and Wieman then produced a pure condensate of about 2 000 rubidium atoms at 20 nK (nanokelvin), i.e. 0.000 000 02 degrees above absolute zero.

  • For although we can estimate the (very short) lifetimes of molecules at temperatures of the sun, and what chemistry might transpire at a nanokelvin or in a vacuum "higher" than that of outer space, the realm of high pressure, such as that at the center of a planet, gives us pause.
