👉 The wheel-particle model, often associated with the concept of dark matter, proposes that the universe is composed of both visible and invisible components. Visible matter, such as stars, planets, and gas, makes up only a small fraction of the total mass-energy content of the cosmos. The wheel-particle hypothesis suggests that the majority of this missing mass consists of weakly interacting massive particles (WIMPs), which are hypothetical particles that interact very rarely with ordinary matter through gravity and the weak nuclear force. These particles are thought to move through space like light particles, or photons, but their interactions are so weak that they pass through normal matter almost undetected. This invisible mass provides the gravitational scaffolding necessary for the formation and stability of galaxies and large-scale structures in the universe, explaining phenomena that visible matter alone cannot account for, such as galaxy rotation curves and gravitational lensing.
