      We think that the universe is made up of 4.6% normal matter, 23% Dark Matter and 72% dark energy.

      The normal (baryonic matter) is all made up of the of protons, neutrons and electrons inside atoms of the elements.

      Dark Matter is some invisible material surrounding galaxies and holds them together.

      Dark energy is dark energy is a hypothetical form of energy that permeates all of space and tends to accelerate the expansion of the universe

      I can’t disagree with that 🙂 It is crazy to think that we can’t see most of the matter and energy in the universe. And the stuff we are made of is rare! It is only a small bit of what is out there…
