"Curiouser, and curiouser" said Alice.
There may be a suite of organic chemical reactions occurring in interstellar space that astronomers haven't considered. In 2012, astronomers discovered methoxy molecules containing carbon, hydrogen and oxygen in the Perseus molecular cloud, around 600 light years from Earth. But researchers were unable to reproduce this molecule in the lab by allowing reactants to condense on dust grains, leaving a mystery as to how it could have formed. The answer was found in Quantum weirdness that can generate a molecule in space that shouldn't exist by the classic rules of chemistry. In short, interstellar space is a kind of quantum chemistry lab, that may create a host of other organic molecules astronomers have discovered in space.
