Dark matter and dark energy are mysterious substances that scientists believe make up most of the universe, but we can't see or detect them directly. Dark matter is thought to be a type of matter that doesn't interact with light, so it doesn't give off any radiation that we can detect. Dark energy is thought to be a type of energy that is causing the expansion of the universe to accelerate. Scientists study these mysterious substances by observing how they affect other things in the universe, such as the movement of galaxies and the behavior of light. They hope to understand more about these substances to help us understand more about the universe and how it works.
