Cosmology Explained on Chalkboard: Dark Matter & Dark Energy

What really makes up our universe? 🌌 Surprisingly, everything we can see — stars, planets, galaxies, and even us — accounts for only 5% of the cosmos. The remaining 95% is made of two mysterious components: Dark Matter and Dark Energy. In this classroom-style chalkboard lecture, we break down: ✔ What Dark Matter is and how it holds galaxies together ✔ What Dark Energy is and why the universe is expanding faster ✔ Evidence from galaxy rotation curves, CMB, and gravitational lensing ✔ Why scientists believe the universe’s fate depends on dark energy ✔ Possible endings of the universe: Big Freeze, Big Rip, or Big Crunch All concepts are explained visually using clean chalkboard diagrams and simple language, perfect for students, beginners, and anyone curious about how the universe really works.
