Universal Expansion is the Receding of Galaxies, Not Space Itself:

I see many posts on the expansion of the universe but those posts read like that of someone inspired by a childlike curiosity about the universe, yet lacking a commitment to rigorously studying science and mathematics.

Unfortunately, these posts convey several inaccuracies, largely rooted in a relativistic bias. Observational evidence suggests that dark energy exerts a repulsive effect, opposite to the attractive force of gravity. This repulsion causes isolated galaxies and galactic clusters to move toward the universe's edges, increasing the distance—and thus the space—between these structures. Although this process makes it appear as though the universe is expanding, it does not imply that space within the universe is expanding.

To clarify, we can observe that space within gravitationally bound systems, such as galaxies, remains unaffected by this expansion. The spatial structure within any galaxy, anchored by its central gravitational forces, does not expand. This phenomenon is feasible only if space itself is not expanding; if the entirety of universal space were expanding, we would see expansion occurring universally, including within each galaxy. However, this is not supported by observational data.

In summary, these posts incorrectly imply that space itself is expanding, a misconception driven by relativistic interpretations that treat space-time as a fundamental entity. This overlooks the concept that time emerges as a result of existential events, rather than as an inherent dimension.
