A Bose-Einstein condensate—a gas so cold that the atoms have lost their individual identity—can act on sound like an expanding universe does on light, either by literally flying apart or by being manipulated using a magnetic field to give the same effect.

一团玻色–爱因斯坦凝聚（一种冷到原子会丧失其个体性的气体），可以像膨胀的宇宙对光的作用一样，来对声音作用，不管是令其飞散，或是用磁场来操纵，都可以得到同样的效应。
