Consciousness is pure raw observation. Observation is measurement in a sense because, whatever tool is receiving data, whether it be a vibration or signal of some sort, the very action of data “movement” changes space time on a quantum level. The double slit experiment is going on all the time so to speak. Is it possible to warp reality slightly by the very act of meditation or a psychedelic mystical experience? Or even with the change of will, the slightest course of reality fractals out into its own universe. It goes on forever. Each reality branches out, subtly different than the previous.
