Vacuum Hum Before the Big Bang

General Projection Geometry proposes a fundamental historical positioning: all spacetime and physics originate from the Big Bang, but before the Big Bang, there existed a "vacuum hum" state — it is the creator of the new universe, and also its observer. This draft starts from the boundary of general relativity and argues for the ontological status of the vacuum hum as the "pre-Big Bang" state, and repositions physical objects such as black holes, the speed of light, and the mass-energy equation within the framework of General Projection Geometry. General Projection Geometry does not seek to replace general relativity, but rather to establish a reference framework outside of spacetime for it.
