Gravity seems holographic. What does that mean for reality?

    Amplituhedron geometry simplifies scattering amplitude calculations.

    N-body gravity derived from QED with scattering amplitudes (without spacetime curvature, in a Flat Minkowski space)

    [...]

    From this chat: <a href="https:&#x2F;&#x2F;share.google&#x2F;aimode&#x2F;O0pKsl6nYdv8Nh2fD" rel="nofollow">https:&#x2F;&#x2F;share.google&#x2F;aimode&#x2F;O0pKsl6nYdv8Nh2fD :

    &gt; The &quot;shear-jamming&quot; of Fedi’s fluid space is the physical, hydrodynamical translation of hitting a geometric boundary facet of the amplituhedron

    And, normed tensor gaussian splatters work well as a simulation primitive for this too because they do conservation.
