是不行的~~ 絕對零度只能逼竟無法等於
是個可論不可得的溫度
==============================================
如果不行, 實驗室可以達成最低溫是幾度?
在1995年兩位美國物理學家將依些鉫厡子的溫度降至絕對零度以上10億分之20度 ~~
很厲害疤~~

我知道的最低溫只達0.002k(很老的資料)

In May 2005, the European Space Agency proposed research in space to achieve femto-kelvin temperatures.[12]
In May 2006, the Institute of Quantum Optics at the University of Hanover gave details of technologies and benefits of femto-kelvin research in space.[13]

上面沒說錯 只能無限接近 就像是光速只能無限接近 縮短會使它速度達不到光速
而且必然無限制地縮短
(假設相對論現在還是對的)
