Dark matter is a special kind of matter that we cannot see. It doesn’t give off light, so it’s invisible to our eyes and telescopes. Even though we can’t see it, scientists know dark matter exists because it has gravity and pulls on things around it. It helps explain how galaxies stay together and move in space.

  • What is Dark Matter: Dark matter is a type of matter that doesn’t shine or reflect light, so we can’t see it. It is invisible but has mass and gravity, which affect stars and galaxies.
  • Why is it Important: Dark matter makes up a large part of the universe. Without it, galaxies wouldn’t hold together properly, and space would be very different.
  • How Do We Know It Exists: Scientists see how stars and galaxies move, and dark matter’s gravity helps explain their movements.
  • Mystery of Dark Matter: Even though scientists know it exists, we still don’t know exactly what dark matter is made of. It remains one of space’s biggest mysteries!
