The Decision of the Maximum Synchronous Torque During the Solar Array Deployment Using the Closed Cable Loop
Abstract: It was a long time since mankind explored and studied the universe, but the early-age power sources have not changed a lot over that period. Solar panels have been used long ago and are still in use today. However, their efficiency has improved considerably. Large and complicated solar arrays are now used instead of simply attaching the panels directly on the face of the satellite. A solar array is essential …

Unified Mass–Energy Dissolution Cosmology (UMEDC): A Staged Framework for Cosmic Energy Transformation and Late-Time Acceleration
Abstract: The ΛCDM model successfully describes the universe’s expansion but remains fundamentally descriptive: it assigns fixed densities to matter, dark matter, and dark energy without providing a unifying physical mechanism behind their coexistence or evolution. In this work, we introduce the Unified Mass–Energy Dissolution Cosmology (UMEDC), a novel framework based on the staged transformation M → DM → DE, where ordinary matter gradually dissolves into a dark-matter-like reservoir, which subsequently transforms …
