The Coma Cluster as a Testbed for Extended Classical Mechanics (ECM):

March 21, 2025

The Coma Cluster, a large galaxy cluster, provides crucial observational data for testing and refining theories about dark energy and gravity. Specifically, it reveals the presence of dark matter and the influence of dark energy's antigravity, particularly at its outer edges.

ECM's Explanation of Dark Energy's Effects:

Extended Classical Mechanics (ECM) offers an alternative to the standard cosmological constant model of dark energy. It proposes that dark energy's influence can be explained by refining classical mechanics, particularly through the concept of "effective mass" (Mᵉᶠᶠ<0). This effective mass accounts for the interplay between matter mass (Mᴍ) and dark energy's antigravity.

Alignment with A.D. Chernin's Research:

A.D. Chernin's studies on the Coma Cluster and dark energy strongly support ECM's principles. His research demonstrates that:

• Antigravity dominates at large radii (R ≳ 14 Mpc).
• The concept of effective mass, which can become negative, aligns with observed antigravity effects.
• Local antigravity effects are also observed.
• The idea of a zero gravity radius, where objects are no longer gravitationally bound, is also supported.

ECM provides a framework that naturally explains these observations without requiring exotic vacuum energy interpretations. It derives antigravity effects from mass-energy interactions, offering a self-consistent model that aligns with observational data from the Coma Cluster.
