Lemaître's Equation

Lemaître's Equation, often related to the expansion of the universe, describes how the universe's rate of expansion relates to its overall energy, mass, and the cosmological constant (dark energy). Essentially, it explains that the universe’s expansion speed depends on these factors. If the energy density is high, gravity slows expansion; if dark energy dominates, expansion accelerates. The equation helps scientists understand whether the universe will keep expanding forever or eventually slow down and contract. It’s a fundamental tool for studying cosmic evolution and understanding the dynamic nature of our universe.
