David Lewis had a crazy but interesting suggestion. According to Lewis, there are an infinite number of universes (“possible worlds”) out there, one for each possible way the world could be. These universes are disconnected from each other in space and time, and set up so that nothing in one universe can cause events in another universe.
Lewis may actually have heard of the physics, but Sinhababu seems to think of many worlds as a purely philosophical construct.
Sinhababu’s 2008 Pacific Philosophical Quarterly article is the definitive essay on acausal ships.
