1. Ordinary Matter (Atoms)

Ordinary matter is the stuff we can see and touch. It includes everything from planets and stars to humans and animals. 

This matter is made of tiny particles called atoms.Objects like Earth, Mars, stars, and even entire galaxies are made from these atoms. Surprisingly, ordinary matter makes up only about 5% of the entire universe.

2. Dark Matter

Dark matter is one of the biggest mysteries in astronomy. Scientists cannot see it directly because it does not emit light or energy. However, they know it exists because its gravity affects the movement of galaxies.

For example, in our galaxy, the Milky Way, stars move in ways that suggest there must be a large amount of invisible matter holding everything together.Dark matter makes up about 27% of the universe.

3. Dark Energy

Dark energy is an even bigger mystery. Scientists believe it is responsible for the expansion of the universe.

In fact, the universe has been expanding ever since the Big Bang.Dark energy pushes galaxies away from each other, causing the universe to grow larger over time. It makes up about 68% of the universe, which means most of the universe is made of something we still do not fully understand.

Final Thought

Even though scientists have learned a lot about space, most of the universe remains a mystery. Only a small portion of it is made of the matter we can see, like planets, stars, and galaxies. 

The rest is invisible dark matter and dark energy that continue to puzzle astronomers.As scientists explore space and study galaxies like the Milky Way, we may one day uncover the true secrets of what the universe is really made of.
