According to the researches by astrophysicists the universe contains about 4.6 percent atoms and the others are dark energy which has the largest portion of the universe of about 71.4 percent and cold dark matter which contains about 24 Percent of the universe.
Atoms are the components of ordinary matter, also called baryonic matter, which only represents 4% of the universe, while the remaining 96% would be formed by what is known as dark matter and dark energy which constitute two of the unsolved problems in physics.
