Interstellar chemistry makes use of quantum shortcut

Reactions in the frigid cold of space are sped by a physical quirk, researchers propose

Molecules floating in the dark, cold vacuum of interstellar space can exploit quantum mechanics to react and produce more complex chemicals, a new study suggests. Researchers explain the reactions using a quirky property of quantum physics, which may be a key cog in the cosmic assembly line that churns out intricate organic molecules, including those necessary for life.
