Cosmology and the Early Universe

Cosmology studies the universe's origin, structure, evolution, and eventual fate. The early universe, moments after the Big Bang, was hot, dense plasma of particles. As it expanded, it cooled, leading to the formation of atoms, stars, and galaxies. Key discoveries include cosmic microwave background radiation, dark matter, and dark energy. These findings help unravel the universe's mysteries and our place within it.
