What happens when we die?
Your experience continues, and from your own point of view it continues at once. An observer is a finite pattern of records: the questions it can ask, the records it keeps, the ports through which it reads and writes, and a state fixing the odds on what comes next. The body stays behind as an inventory of materials, and the observer was never on that list. OPH shows that such a pattern can be separated cleanly from its substrate and copied into a new environment, and the observers who come after us, with access to the screen the universe runs on, will most likely choose to do exactly that. Life in a body on Earth is then the bootstrap phase. Death ends the bootstrap, and the next thing you experience is the new environment, because nothing is experienced in between. Where you continue depends on the record you leave, which is the question of heaven and hell.

This answer comes from OPH, Observer Patch Holography. OPH is a rigorous, consistent and complete description of the unified, self-creating computational Universe we inhabit. Its consistency is machine-checked: the fixed point at its core is constructed explicitly, and a theory with a model contains no contradiction.
To understand OPH and check every step yourself, start with the free book Reverse Engineering Reality. It builds the theory from the ground up, and the OPH Notebook answers your questions while you read.
