%0 Journal Article %T The collapse of supertasks %A Gustavo E. Romero %J Physics %D 2013 %I arXiv %X A supertask consists in the performance of an infinite number of actions in a finite time. I show that any attempt to carry out a supertask will produce a divergence of the curvature of spacetime, resulting in the formation of a black hole. I maintain that supertasks, contrarily to a popular view among philosophers, are physically impossible. Supertasks, literally, collapse under their own weight. %U http://arxiv.org/abs/1309.0144v1
