We sketch the construction of a quantum model of 3 dimensional de Sitter space, based on the Covariant Entropy Principle and the observation that semi-classical physics suggests the possibility of a consistent theory of a finite number of unstable massive particles with purely gravitational interactions. Our model is holographic, finite, unitary, causal, plausibly exhibits fast scrambling, and qualitatively reproduces features of semi-classical de Sitter physics. In an appendix we outline some calculations that might lead to further tests of the model.

  1. New Modes for Vector Bosons in the Static Patch

    hep-th 2024-12 conditional novelty 6.0 of 10

    A massive vector boson in a de Sitter static patch has a stability edge at μ_v^2 = m_v^2 + 2(D-1)ℓ^{-2}, permitting naively tachyonic Lagrangian masses down to m_v^2ℓ^2 = -2(D-1).

  2. Singularities, Entropy and the Arrow of Time, {\it or} Is CRT a Gauge Symmetry in Quantum Gravity?

    hep-th 2026-07 conditional novelty 5.0 of 10

    CRT is an asymptotic gauge symmetry in flat/AdS quantum gravity, not a true gauge symmetry, and is absent or only spontaneously broken under special untestable conditions in de Sitter cosmologies.
