Cosmology is the study of the origins and evolution of the Universe. Cosmos is actually just another word for universe. My favorite theory is the theory of the Multiverse (thank you Spiderman!) This theory states that we are just one bubble in an infinite series of bubbles, and that the differences between the Universes are called “parallel universes”. Together, the universes comprise of everything that exists, and that is infinite as we grow, change and evolve. It is hard to wrap my head around sometimes, but I really became interested in it thanks to the Spiderman movie!
