7. Basic Quantum Physics, QMA.

Summary

Basic quantum physics is defined. In it, there are no particles, no collapse, and no sentient beings outside the laws of quantum physics.

Since quantum physics is so successful (principle [P3] in Schrödinger’s Cat), we will describe a scheme, called QMA, in which

*all there is*is ‘basic’ quantum physics.

[P4] Basic quantum physics, QMA is defined as follows:We will find in succeeding sections that this bare-bones theory, with no particles or collapse, does very well in describing our perceptions. The only place where it falls short—and it is a fatal short-coming—is in being consistent with the Probability Law.

(1) No particles. There are to be no particles or hidden variables.

(2) No Collapse. There is to be no collapse of the wave function, so that all versions of reality continue forever.

(3) No ‘sentient beings.’ There are to be no ‘sentient beings,’ outside the laws of quantum physics, which ‘look into’ physical reality and perceive just one version of reality.

(4) No probability law. There is to be noa prioriassumption that the probability law holds.

(5) Linearity. And finally, the theory is to be linear. (This is a technical point which basically implies that each version of reality is isolated from the others.)
