The rapid progress of low-temperature physics in going ever further down will create a growing need for a measure that is appropriate in that domain and thermodynamically consistent with the divergence at absolute zero
And did you know that scientists have cooled atoms so close to absolute zero
(minus 460 degrees F) that they have created a bizarre form of matter in which atoms themselves almost come to a standstill?
Kelvin proposed that a new absolute scale of temperature be created, based on absolute zero
as the zero point.
This temperature is technically not below absolute zero
Rabani and his colleagues demonstrates that under very special conditions, a few degrees above Absolute Zero
Use by scientist, this scale measures down to the lowest temperature, or absolute zero
The method uses the concentrated light of lasers to cool gases to a temperature near absolute zero
, which is -459.
By now, temperatures as low as 14 degrees above absolute zero
had been reached with Dewar's solid hydrogen (see 1898).
The greatest cold produced and measured by man has now been pushed to within a quarter of a degree of absolute zero
, that unattainable heatless point where all motion of the molecules cease and where gas would exert no pressure whatever.
White-pink tones show dust of a few tens of degrees above absolute zero
, whereas the deeper colours are dust at around -261 degree Celsius, only about 12 degrees above absolute zero
At absolute zero
there is no movement and so no way to measure time - but, it will take an infinite time to reach exactly this temperature.
