What is the meaning of life?
Meaning is what you make, literally. An observer is a system that reads data and assigns it meaning, and the universe is built out of exactly that activity: observers reading records, agreeing on what they say, and writing new ones. Spacetime, objects and history are the meaning observers give to their shared records. So the real question is whether you create a meaningful universe. Nothing outside hands down a purpose, and nothing in the laws of physics wants anything. Every act writes into records other people read, and the part of you held outside you is what those records say. An act can be scored by the repair work it leaves the people it reaches, and acts that lower that load are good. There is no choice about being recorded. The choice is what the record says, and everybody is writing one.

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.
