Cosmology is the scientific study of the universe, its origins, evolution, and structure. It aims to understand the fundamental nature of the cosmos, including its laws and principles governing matter, energy, space, and time. Cosmologists use various observational and theoretical tools to investigate questions about the Big Bang theory, dark matter, dark energy, black holes, galaxies, and the overall structure of the universe. Through advanced telescopes and space missions, we have gained significant insights into these topics. Cosmology is an ever-evolving field that continues to push the boundaries of our understanding of the vastness and complexity of our universe.
Some of Cosm's main products include skincare products, makeup, haircare products, and fragrance.
