Chapter 23: Dark Energy as Readout Artifact

In 1998, observations of Type Ia supernovae riess1998observational,perlmutter1999measurements revealed that the expansion of the universe is accelerating. The standard cosmological model (ΛCDM) attributes this acceleration to a cosmological constant Λ—a uniform energy density filling all of space, comprising ∼ 68% of the total cosmic energy budget. This substance is called dark energy. Nobody knows what it is. Its only observational signature is the acceleration itself.

This chapter demonstrates that the acceleration is real but the dark energy is not. “Dark energy” is diagnosed as a readout artifact: a base-progression phenomenon on τ¹ misinterpreted as an energy component by the orthodox readout functor. No cosmological constant is needed. No new energy component exists. The 68% of the cosmic budget attributed to dark energy vanishes when the correct readout is applied.

The structural dissolution is τ-effective: it follows from the thermodynamic inversion (Chapters 21–25), the τ-Einstein equation (Part II), and the cosmological readout . The quantitative prediction for the acceleration rate is conjectural: it depends on the detailed dynamics of the defect exhaustion process at the current cosmological epoch.
