  As a layperson, I feel incredibly lucky to be able to "eavesdrop" on conversations like these.

  Thank you Sean.  Greatly appreciate your talk.

  I think there&apos;s a typo on the slide at <a href="https://www.youtube.com/watch?v=HOssfva2IBo&amp;t=245">4:05</a>. He accidentally writes the definition of a Banach space rather than of a Hilbert space. (Below that he shows an inner product, rather than just a norm, so I don&apos;t think it was intentional.)

  Hilbert space describes <b>another</b> system, not the reference system. So there cannot be a system that describes <b>itself</b> in a Hilbert space.

  I love Sean saves Schrodinger&apos;s cat 🐈. It was abused too much.<br><br>Change in area=change in entropy=change in local speed of light? <a href="https://www.youtube.com/watch?v=HOssfva2IBo&amp;t=2460">41:00</a> VSL theory language may be more natural, than GR one(putting aside the fact it is more general, because of the nonlinear dispersion).

  We need a wave superfunction. &nbsp;Also, waves don&apos;t propagate in Euclidian-like vacuums.

  Finally someone is on the right track without having listened to the rest of the video. This particle travelling in the one dimension allows for c to be constant (a displacement distance), it is able to travel from discrete to continuous and back to discrete nature which gives you equal pathtimes so that c is constant and does away with the illusion of general relativity while keeping everything conserved. Basically using the 2nd and 3rd dimensions to transverse continuously to get to next discrete 1 dimensional point.

  Thank you. I call on my spirit guides, the archangels and ancestors for help in life today. may you be blessed

  Can this approach of factorization of the Hamiltonian in the Hilbert space lead to a hierarchical structure of the universe: galaxies, groups of galaxies, clusters of galaxies, super-clusters of galaxies, clusters of super-clusters of galaxies, universes like our observable universe, and then Big Attractor as the entire universe.
