This theory suggests dark matter consists of axions, forming structures through primordial black holes, implying new insights for cosmology.
EUT 4.0 is the final, minimal version of the Eternal Universe Theory. All scalar fields, white holes, and exotic energy mechanisms are removed. Dark matter consists exclusively of axions produced via the vacuum misalignment mechanism. Primordial black holes (PBHs) with abundance f_PBH < 0.01 serve as gravitational seeds for structure formation. Cosmic voids amplify axion density through temperature-dependent phase stabilization, yielding Ω_DM ≈ 0.25 and Ω_DE ≈ 0.7 without fine-tuning. The theory is eternal, local, and fully falsifiable by upcoming experiments (Euclid, LISA, CMB-S4). Time emerges with the first detected photon.
