Socks that become lost in your washer or dryer are now being investigated as indisputable proof that M-theory is, indeed, a valid hypothesis to explain all existence.
Apparently, vibration along the strings that make up all matter in the universe allows certain articles of clothing, when heated to the correct temperature and set into a tumbling motion, to seemingly disappear.
M-theory, as most people will recall, insists that multiple dimensions exist right next to the 4 we know, but are impossible for the human brain to process. Small inanimate objects, unaware that these extra dimensions are "hidden," are able to slip through to these other dimensions when conditions are precisely correct, much the way you or I might slip effortlessly through an open door, but would break our noses trying to walk through a closed door.
