The Bekenstein-RSI information link

The Bekenstein Bound sets a limit on how much information a finite region of space can hold. Applied to the cosmic horizon, it implies the observable universe contains on the order of 10¹²² bits. This follows from the horizon's area in Planck units.

RSI notes how close this number is to the 10¹²⁰ vacuum energy discrepancy. The paper suggests the cosmological constant problem may be a misreading of what vacuum energy represents, rather than a simple failure of QFT.

The Holographic Principle holds that the contents of a volume are encoded on its boundary. Following it, RSI holds that the internal energy of any region of the medium is projected from, and constrained by, the 2D surface that bounds it. For the observable region of the universal torus, that surface is the cosmic horizon, and the 10¹²² bits are the count of Inversion Pixels needed to maintain the 0.73 N baseline tension across the observable volume. The whole torus, which RSI estimates at about 1.65 × 10³¹ meters across, extends far beyond that horizon. We do not measure this energy because it is not a force on the medium. It is the stiffness of the medium itself.
