Which brings up an interesting question. Does the chemical make-up that comprise the olfactory molecules travel in space and detectable by the olfactory nerves in the nostrils? Probably not, but if they do, no one may actually hear you fart in space but especially if it is only the two of you, they’ll know you transported unauthorized contraband methane gas and then be subject to the class-3 felony punishment in which importing methane gas is strictly enforced.
