What a great question! You’re certainly asking us some hard ones Roony. This is a question that people have asked for as long as people can ask questions and one that scientists are still trying to figure out today.

The Universe is made up of three different types of stuff: normal matter, dark matter and dark energy.

Normal matter is all the things that you can think of in the universe – the planets, the stars, people, animals, plants and objects like tables and XBoxes. All these things are made up of atoms. Atoms are the building blocks of objects and life. So everything you can see around you is made up of atoms. Only a small part of the universe it made up of normal matter, or atoms, though.

Most of the universe is made up of dark energy. Dark energy is what fills all the empty space in the universe. Scientists are still trying to full understand what it is. Its funny to think that empty space is full of something! The rest of the universe is made up of dark matter. Because dark matter is, well dark, we can’t see it to really understand what it s. We know it is there because it effects the stuff around it.

Maybe you can grow up and become a scientist so you can help find out what dark energy and dark matter really are?!

If you’re interested in space, did you know that the Britain, as part of Europe, has a space agency – our very own NASA? We send rockets and astronauts to space to try and answer some of these questions. The European Space Agency have a great website all about the universe and space here: http://www.esa.int/esaKIDSen/SEMX4EBE8JG_OurUniverse_0.html
