The universe is full of mysteries, and two of the biggest ones are
Dark Matter and Dark Energy 🧠✨

They are called “dark” because we can’t see them, but we know they exist!

🌑 What is Dark Matter?

🔍 What it does

• Dark matter is invisible matter
• It does not give light
• But it has gravity

👉 Gravity from dark matter holds galaxies together

🌀 Why do scientists believe in it?

• Stars in galaxies move too fast
• Without extra gravity, galaxies would fly apart
• Dark matter provides the missing gravity 🧲

🧠 Easy example

🧠 Easy example

Imagine dots on a balloon 🎈
As the balloon inflates, the dots move apart.
