Global Geometric Architecture (GID Theory)

A formal theoretical development of the Global Geometric Architecture Theory (GID)

is presented as a geometric and deterministic alternativeΛCDM paradigm. In contrast to

inflationaryscalarfieldsandaninitialtemporalsingularity,GIDpostulatesthattheobserv-

ableUniverseemergesfromanintrinsicallyinhomogeneousglobalgeometrystructured by

threecoherenthorizon-scale energydomains: ID0,ID1,and ID2.

Two fundamental equations define the theory: (i) a geometric extension of Einstein’s

fieldequationsinwhichthecosmologicalconstantΛisreplacedbyaneffectivecontribution

to the energy–momentum tensor generated by the three domains; and (ii) a global closure

relation stating that all large-scale cosmological observables are governed by the coupled

dynamics of these domains. The present cosmic state results from a process of geometric

erosion,correspondingtoa60–75%redistributionofthefoundationalmass-energycontent.

The theory remains entirely within General Relativity, removes the physical necessity

of both a Big Bang singularity and inflation, and yields a set of falsifiable predictions for

CMB anisotropies, coherent bulk flows, Hubble-parameter anisotropy, Integrated Sachs–

Wolfe (ISW) signals, and ultra-early structure formation. The framework is designed

for direct empirical testing with Euclid, DESI, and forthcoming peculiar-velocity surveys
