    It’s going to take some time to unpick all this but if this survives tests of the neutrino masses, the sheer scope and power of this is beyond jaw-dropping. Right now it seems to me bigger than Einstein’s entire career

    Fellow South African expat here University of Cape Town mechanical engineering degree living in Portland Oregon USA. Physics has been my hobby for 30 years. Thank you Neil for all you have done for theoretical physics. Baie lekker:)

    For neutrino mass to represent the results of the gravity of dark matter would be astonishing.
    Very interesting

    Our world looks like the inside of a black hole, the horizon is a big bang, time is the collapse inside it, expansion is where we are inside it. (layman's couch meditation)

      It, really, is a BH. Watch Susskind lectures.

      Yes, 100%
      And think of all the many other universes that
      are located in the enormous number of
      black holes.

      Neutron decay cosmology
      The path of least action, physical process solution to black hole paradoxes, dark energy, dark matter and critical density maintenance.
      A homeostatic universe maintained via the reciprocal processes of electron capture at event horizons and free neutron decay in deep voids.
      Gravity gathers mass to event horizon.
      Because of electron capture ONLY neutrons contact event horizon.
      They drop kinetic energy off at event horizon as mass for it.
      Then take an EinsteinRosen bridge from highest energy pressure conditions to lowest energy density point of space.
      From maxima to minima
      Re Emerging in a deep void somewhere.
      There the neutron soon decays
      Into amorphous monatomic hydrogen
      Dark matter. Proton electron soup.
      Cross section around 10-³¹ barn.
      The decay from neutron 0.6fm³ to one cubic meter of amorphous hydrogen is a volume increase, EXPANSION, of 10⁵⁵.
      Dark energy.
      As well, given PV=nRT and an expansion of 10⁴⁵ means a corresponding temperature drop.
      No wonder space is still cold.
      In time the amorphous hydrogen stabilizes and scintillates and follows the usual evolution pathway until at some point on the distant future that neutron is again about to contact an event horizon.
      Time is a compactified dimension one single Planck second in size.
      The closure to the universe is continuous.
      Neutron decay cosmology
      Inevitable

    15:52 DESI does not show that. A varies a lot. We seem to be surrounded by intense clusters smoothing out to large quasar groups and then the CMB

    Great conversation. There will be a big surprise for everyone soon. Base Twelve Mathematics - surprisingly - will save the day in terms of revealing a geometry which is currently not available to us in base ten. The geometry of the Universe is in base twelve and gives rise to a type of geometry which is able to accommodate the empty space inside of everything, and the base twelve version of Pi which emerges from this geometry has different characteristics from what we think Pi is. It gives rise to a geometric structure within the circumference of the circle which eventually solves the problem of infinity by giving structure to the smallest of the small, as well as access to the environment in which it resides. It will open up many avenues for exploration, and eventually lead us through the journey from quantum to the stars.

    If you are going to get rid of the quantum gravity renormalization problem by adding those 36 fields that have no particles, I assume you have to make some assumptions about how those fields interact with the Standard Model fields. Isn't that a significant addition to the Standard Model? I don't understand how to judge simplicity of a model so I can't tell if that is better than, say, string theory with whatever number of dimensions and topology required to make things work.
    Oppenheim's post-quantum gravity approach doesn't add new particles or dimensions AFAICT but the equations are complex enough to need new tricks to fit on a page that I haven't seen before. It is an objective collapse scheme. Does your story have wave functions objectively collapsing? If not, what do you think should be done about the measurement problem?

    If live in a flat universe, how thick is this flat space? I'm guessing that its thickness is time itself.

    • @andymccracken4046
      @andymccracken4046 4 месяца назад +1

      The flatness of space isn't about thickness - what it means is that it isn't curved space - this means that 2 parallel lines never get closer together or further apart. It sounds obvious but it would happen in a curved space.

    Never underestimate the human's proclivity for complicating everything it can. Simplicity in nature is considered esoteric and philosophical by today's scientific community. Ego is the order of the day.

    Inflationary guys can't get pass their fact that the theory has more holes than swiss cheese and after so many years of trying the theory still has more inputs than product....and the crazy eternal inflation rabbit hole.

    • @trucid2
      @trucid2 8 месяцев назад +1

      As a layman I don't know how anyone can take inflation seriously. It's the most egregious example of a fudge factor I've ever seen. Equations came out 1 = 2? No problem, just add 1 to the left side and say that it works!
