A Space-Energy Conversion Model: A Unified Framework for High-Energy Events and Cosmic Expansion without Dark Energy

We propose a novel space-energy conversion model that redefines space as a dynamic entity responsive to high-energy events, ranging from chemical explosions ($10^6$ J) to supernovae ($10^{37}$--$10^{40}$ J) and gamma-ray bursts (GRBs, $10^{46}$--$10^{47}$ J), spanning 10 orders of magnitude in energy. Unlike general relativity’s passive spacetime, this model posits that energy release triggers a non-linear, entropy-increasing conversion, analogous to matter-antimatter annihilation, producing a residual energy state in space. A material shielding effect, \(\alpha(\rho_m) = \frac{\alpha_0}{1 + k \rho_m}\), explains the absence of expansion in galaxy clusters and accelerated expansion in cosmic voids without dark energy. The shielding parameter \(k\) is derived from quantum vacuum suppression, incorporating the Hubble length. Using 2023--2025 public datasets (DES, ZTF, Fermi, Swift), we validate the model across 50 events (25 supernovae + 25 GRBs). Statistical analysis (power-law fit, exponent $\sim 1.03$, $p<0.001$) confirms cross-scale consistency. Unique predictions include transient gravitational waves, TeV photon excess at high redshift ($z>5$), and neutrino pulses, testable with LIGO, JWST, and IceCube. Compatible with general relativity in the weak-field limit, this framework unifies micro- and macroscopic physics, offering a paradigm-shifting alternative to \(\Lambda\)CDM.
