Cosmology Series | Phase 1 – Development of the Stardust

Introduction and Philosophy of Cosmology 


Cosmology and astronomy is maybe the oldest science of humanity. It just began with wondering about shiny dots in the night sky, which we call stars now and it led us to the cosmology and astronomy we have today, which is way more complex than wondering about the shining stars. It’s much more than a science subject, a concept for star wars and a background for night events. It is our feeling for our place and life in this vast ocean of universe and we live in a tiny but warm Island, Earth.

The first thing I would explain is that Cosmology and astronomy are not the same things. Astrophysics is the discussion about planets, stars, galaxies, celestial bodies and celestial happenings. whereas Cosmology discusses the Universe as a whole, It’s origin, evolution and it’s Fate. Astrophysics is the inspiration for enthusiasts in the beginning but Cosmology is the destiny to understand the farthest origin of existence. The knowledge humanity has gained in cosmology is far more than expected but also crazy. The cosmology today gives an explanation to the Origin and existence of our Universe. The Origin of the Universe is the oldest and first discussion of cosmology. The famous idea of the big bang is not unheard from any common man, but that idea has much more truth unwrapped to human knowledge, which we haven’t found yet, but we have some intuition for it.

Beginning from the Origin, we have today reached a broader perspective for cosmology, which includes many thoughtful ideas like, the expantion, Inflation and also many over-talked and misunderstood topics like Dark matter and multi-verse. The knowledge of cosmology have grown like a domino effect, but during this quick and heavy growth, many fundamental and philosophical questions still exist and has become more difficult to answer.

There is a load of discussion and description in the next articles of this series. The approach will be to discuss the necessary and interesting concepts but keeping them simpler to understand. You will not be able to calculate the age of the universe at the end of this series but you will get to know the cosmology in a more deeper way, which not usually discussed in science media for the general public.
