Cosmological Parameters

Cosmological parameters are key numbers that help scientists understand the universe's structure, history, and expansion. They include values like the Hubble constant, which measures how fast the universe is expanding, and dark matter and dark energy densities, indicating the mysterious forces that influence galaxy movement and cosmic growth. These parameters are essential for building models of the universe, interpreting observations from telescopes, and understanding phenomena such as the Big Bang, galaxy formation, and the ultimate fate of the cosmos. Together, they provide a framework for exploring the universe beyond our Milky Way galaxy.
