DARK MATTER

All te viible matter in the uiverse—including all the planets, stars, and massive galaxies—makes up only 5% of everything that exists.
That means the remaining 95% of the universe is completely invisible. We can't see it at all, and scientists call this mysterious, missing part Dark Matter.
What is Dark Matter?
Dark matter is a strange phenomenon:
It does not reflect light.
It does not absorb light.
Instead, light passes straight through it.
Because of this, we cannot see it with our eyes, nor can we detect or "touch" it with any machine or scientific instrument. It is all around us, yet completely invisible.
How Do We Know It Exists?
If it is totally invisible, how do scientists even know it’s there?
The answer is gravity.
We know that every galaxy in the universe is spinning at an incredible speed. According to the laws of physics, they are spinning so fast that they should have flown apart and scattered into deep space long ago. But they don’t.
Galaxies stay bound together because an invisible force is holding them in place like cosmic glue. That force is the gravitational pull of Dark Matter. We might not be able to see it, but we can clearly see its massive effects on the universe.
The Ultimate Question
So, what is Dark Matter actually made of?
Well, that is a secret the universe is still keeping—because even the world's top scientist
