The Universe is thought to consist of three types of substance:
Ordinary matter, Dark matter and Dark energy.
>>Ordnary matter consists of the atoms that make up stars, planets, human beings, and every other visible object in the Universe.
>>Dark matter is composed of particles that do not absorb, reflect or emit light, so they cannot be detected by observing electromagnetic radiation. Dark matter is material that cannot be seen directly. We know that dark matter exists because of the effect it has on objects that we can observe directly.
>>Dark energy is a hypothetical form of energy that exerts a negative, repulsive pressure, behaving like the opposite of gravity.
