The hourglass universe

الجزء الثاني: باللغة الإنجليزية (English Version) Subject: Submission of Scientific Report: Hypothesis on the Dynamically Gradient Density of Gaseous Spacetime Dear Professors and Colleagues, I would like to share with you a concise scientific report that introduces a novel cosmological paradigm regarding the fundamental nature of the cosmic fabric. This research posits a mechanical and geometric hypothesis wherein spacetime is treated as a fluid-like entity—a miscible gas intrinsically linked to local time—characterized by a dynamic density and thermal gradient that transitions from a heavy-hot state to a light-cold state through a kinetic sorting process analogous to fractional distillation. This model offers an alternative mechanical explanation for the forward structural expansion of the universe and certain observational anomalies, such as thermal anisotropies in the Cosmic Microwave Background (CMB). Please find the updated scientific report attached below in both Arabic and English. I would highly appreciate your academic feedback, constructive criticism, and insights regarding this hypothesis and its mathematical development. Sincerely,
