There is no gap between his death and his continued life, no possible spacetime in which he isn't. He is the Force and the Force is as intrinsic to the Universe as gravity is. When the Death Star explodes and his mortal body dies, he feels its cells violently split apart into their component atoms, feels the molecules of the station violently split apart into their component atoms, feels atoms collide against atoms in a massive release of energy that ripples through the subatomic to his elemental soul.
