Atoms find quantum solace in the deep chill of space

By Lisa Grossman SPACE is cold, really cold. That should mean very little happens, and yet there are stars, planets and people. Now an ultracold experiment could help explain how chemical reactions get started in the freezing near-vacuum of interstellar space. It seems that, far from staying aloof, some atoms actually find it easier to get cosy with each other at temperatures close to absolute zero, which is -273.15 °C, or 0 kelvin. The reason could be to do with that well-known mischief-maker, quantum physics,
