[QUOTE="PAllen, post: 5466496, member: 275028"] Often a wooden board will curve as it ages, if it hasn't been dried properly. This is known as plank curvature. Alternatively, ancient ship builders dried planks under stress to build hulls, resulting in plank curvature. The relativistic generalization of this adds a c. Real answer: The following is the very first google hit for "Planck curvature". Good form asking a question here is to show some sign of having spent more than 5 seconds trying to find the answer, and framing your question in relation to the result of such effort.
