Why is the cosmological constant so small?
On a proposed OPH branch, the cosmological constant is small because the horizon is large. In Planck units it equals three pi divided by the number of records your cosmological horizon can hold, about 3.3 × 10¹²². The puzzle comes from adding up the zero-point energy of empty space, which overshoots the sky by roughly 120 orders of magnitude. Gravity's local probes are light rays, and vacuum energy looks the same to every observer at any speed, so it is a number times the metric, the geometry's ruler. Along any light ray the metric reads exactly zero, so the light-ray balance leaves that number undetermined. The vacuum-energy problem stays open, and other local measurements remain possible. The candidate record counts give values within one percent of the Planck value, a comparison made after the fact. The branch predicts dark energy that never changes, so an established change over time would rule it out.

This answer comes from OPH, Observer Patch Holography. OPH is a rigorous, consistent and complete description of the unified, self-creating computational Universe we inhabit. Its consistency is machine-checked: the fixed point at its core is constructed explicitly, and a theory with a model contains no contradiction.
