What is Universe?

Understanding the Universe: A Simplified Guide

The universe is everything. It's the vast expanse filled with planets, stars, galaxies, and everything we can't even see. It's constantly changing and growing, and scientists are still trying to figure it all out.

What's inside the universe?

Most of the universe is made up of mysterious things we can't see: dark matter and dark energy. We can feel their effects, like gravity pulling things together, but we don't know what they are.

The other stuff, the stuff we can see, is called ordinary matter. This includes planets, stars, galaxies, and even us!

How do we learn about the universe?

Scientists use telescopes to look at the universe from afar, like staring at distant stars and galaxies. They also send spacecraft out to explore planets and other objects up close.

What are the biggest mysteries of the universe?

There are still many things we don't know about the universe, like what dark matter and dark energy are, how the universe started, and if there's life on other planets.

Is there an end to the universe?

We don't know! The universe is constantly expanding, and we haven't found an edge yet.

The universe is a big and amazing place, and there's still so much to learn. It's a journey of discovery that will never end!
