ΛCDM Model

The ΛCDM (Lambda Cold Dark Matter) model is the leading scientific framework describing the universe's structure and history. It suggests the universe is made up of ordinary matter, dark matter (an invisible form that exerts gravity), and dark energy (a mysterious force causing accelerated expansion). The "Lambda" (Λ) represents dark energy, while "Cold Dark Matter" refers to slow-moving dark matter particles. This model explains how the universe evolved from the Big Bang, how galaxies formed, and why the universe is expanding faster over time, providing a comprehensive understanding consistent with observations.
