The document discusses dark matter and dark energy in the universe. It states that the universe is estimated to consist of 70% dark energy, 25% dark matter, and less than 5% normal matter. Dark energy is blamed for the accelerating expansion of the universe, but its exact nature is unknown. Several hypotheses for dark energy are presented, including that it is a property of space or results from quantum fluctuations. More data is needed to discriminate between theories of dark energy. Dark matter is also not well understood, but is thought to not consist of normal matter like stars, planets, or black holes. Leading candidates for dark matter are axions or WIMPs. Recent telescope observations provide further evidence that dark matter interacts differently than
