The Mysterious Cosmos: Unveiling the Secrets of Regular Matter, Dark Matter, and Dark Energy
Our universe is a vast and enigmatic place. While we can observe countless stars, galaxies, and nebulae, recent estimates suggest that only a tiny fraction, roughly 5%, is composed of the familiar matter that makes up everything we see and touch [1]. The remaining 95% is shrouded in mystery, dominated by two enigmatic substances: dark matter and dark energy. Understanding these invisible components is one of the greatest challenges facing modern cosmology. Regular Matter: The Building Blocks We Know Regular matter, also known as baryonic matter, consists of the atoms that form everything around us – from the air we breathe to the stars that light up the night sky. Atoms are composed of even smaller particles called protons, neutrons, and electrons. Protons and neutrons reside in the nucleus, while electrons orbit around it. The specific arrangement of these subatomic particles determines the element, and the combination of elements creates the vast diversity of materials in the univers...
