The universe is a vast and mysterious place, filled with a wide variety of celestial bodies and natural phenomena. From the stars that light up the night sky to the black holes that bend the very fabric of space and time, there is much to explore and discover.
This glossary is designed to provide a basic understanding of some of the key terms and concepts related to the universe and nature. Whether you're an aspiring astronaut or simply curious about the world around you, these terms will help you navigate the cosmos and appreciate the beauty of nature.
- Universe - the vast expanse of space and all the matter and energy it contains
- Nature - the physical world, including all living and nonliving things
- Cosmos - the universe as a whole, including all of its galaxies, stars, and other celestial bodies
- Astronomy - the study of the universe and its workings
- Astrology - the study of the movements and relative positions of celestial bodies in the belief that they have an influence on human affairs
