BranchingPoint__F7yiEKOfEd-WfYQ0GneCwQ_subTitle=Temperature is a mearure of microscopic motion. A gas close to absolute zero temperature consists of almost immobile particles. It condenses, in a sense like atmospheric moisture in a room at the window-pane or at dust particles. <p></p> <p>The distinction\: at a billionth part of a degree the particles condense mutually, in a way; they do no longer need an interface or condensation nuclei for it - and they do it for quantum mechanical reasons. The figure shows a simulation where more and more particles accumulate near the state of rest.</p> <p><i>Bose-Einstein-Condensates</i>, as these coldest gases of the universe are coined, are artificial products. The space, at about 2.73 degrees, is much too warm so as to allow them to freely exist.</p>
