That is my point. Decoherence falsifies collapse. Exactly.
Decoherence falsifies many worlds.
Decoherence is just the contagion of superposed states to the observer/
environment. It vindicates the many-worlds.
Many-worlds is not an interpretation, but an easy consequence of the
linearity of the wave, and the linearity of the tensor product.
That is so true, than when the founders got this, they introduces a
new axiom for the measurement which basically says that quantum
mechanics is wrong for the observer, to avoid the spreading of the
superposition. But that is ad hoc, and contradict the idea that
physicists obeys to physical laws.
With decoherence everything is a wavefunction and those wave
functions just keep on going and interacting in this single world.
The waves don't interact, and the superposition, by linearity, never
disappeared, and spread at light speed.
QM-without-collapse = MW.
Explain me with only QM how a branch of the wave could ever disappear.
Then with comp, arithmetic contains all dreams, and QM becomes the
digital seen from a first person plural points of view. the math
confirms this up to now. This makes "mono-universe" still less
plausible.
