The universe is made up of three main types of substances: normal matter, dark matter, and dark energy.
Normal matter is made up of atoms, which are the smallest unit of ordinary matter. Atoms are made up of protons, neutrons, and electrons. Protons and neutrons are found in the nucleus of the atom, while electrons orbit the nucleus.
Dark matter is thought to be made up of particles that do not interact with light or other forms of electromagnetic radiation. This makes it very difficult to study, but scientists believe that it is made up of weakly interacting massive particles (WIMPs).
Dark energy is thought to be a form of energy that is causing the expansion of the universe to accelerate. Dark energy is very mysterious, and scientists are still trying to understand it.
The universe is a vast and mysterious place, and we are still learning about its composition. The three main types of substances that make up the universe are normal matter, dark matter, and dark energy. We know a lot about normal matter, but we know very little about dark matter and dark energy. Scientists are still working to understand these mysterious substances, and they hope to one day unlock the secrets of the universe.

The composition of the universe is still a mystery, and scientists are working hard to learn more about it. By studying the distribution of matter and energy in the universe, scientists hope to one day understand what dark matter and dark energy are and how they work.
