What is Cosmology?
Cosmology is the study of the origin of the universe, how it became what it is today, and how it continues to evolve.
COSMOLOGY MEANING
To uncover whether the universe has underlying order, it is essential to understand how, or if, the universe began. And to believe that the universe has purpose begs some understanding of how it all came to be.
Here you'll find a diverse collection of articles, videos and other resources that elaborate on cosmological models, theories, and research for a deeper understanding of how our universe works and what its purpose may be.
