Content of the Universe Pie Chart

Planck data reveals that the universe's contents include 4.9% ordinary matter, or atoms, the building blocks of stars and planets. Dark matter comprises 26.8% of the universe. This matter, different from atoms, does not emit or absorb light. It has only been detected indirectly by its gravity. 68.3% of the universe, is composed of "dark energy", that acts as a sort of an anti-gravity. This energy, distinct from dark matter, is responsible for the present-day acceleration of the universal expansion.
