The Sock Hole Theory proposes that the holes in socks are not mere defects, but rather, portals to other dimensions. The more holes, the more portals. The bigger the holes, the more unstable the portal.
Researchers estimate that 9 out of 10 socks possess at least one hole, but only 3 out of 10 have a hole large enough to swallow a human.
