We cloak it in meaning and make up stories about what will happen to us, but we don't really know. When a person dies, we cannot see beyond the corpse. We speculate on reincarnation or talk in terms of eternity. But death is opaque to us, a mystery. In its realm, time ceases to have meaning.
All laws of physics become irrelevant.
Death is the opposite of time. Certainly not the body, which falls into its constituent parts of water and chemicals. That is mere transformation, not destruction. We don't know for sure, and few can come up with anything conclusive. Nothing of the person dies in the sense that the constituent parts are totally blasted from all existence.
