I suppose most of us have wondered why there are, as far as we know, no moths in space, apart from the fact that, if there were, they would fly directly towards the billions of suns out there and be burnt to nothingness. But space will probably be forever moth free because it smells like mothballs, which astronauts could attest to if they could only remove their helmets to take a whiff.
In addition to its mothball odor, space is also greasy, a fact that may explain, in addition to lack of friction and being a vacuum, why things can travel so fast through it. What's more, there is silica like sand in space, which, along with the grease, brings to mind a beachcomber with sand stuck to their sunblock. The universe is mysterious.
