Some key physical entities such as empty space, elementary particles and the wavefunction appear to be purely mathematical int he sense that their on… - Max Tegmark

(…) the . Here we interpret the wavefunction for an object as describing not some funky imaginary ensemble of possibilities for what the object might be doing, but rather the actual spatial collection of identical copies of the object that exist in our infinite space. Moreover, quantum uncertainty that you experience simply reflects your inability to self-locate in the Level I multiverse, i.e., to know which of your infinitely many copies throughout space is the one having your subjective perceptions.

the challenge for physics is deriving the consensus reality from the external reality, and the challenge for cognitive science is to derive the internal reality from the consensus reality.

We have to get away from this idea today with some fact-checking sites which might themselves have an agenda and you just trust it because of its reputation. You want to have these sort of systems [where] they earn your trust and that is completely transparent.
