DARK ENERGY A MYSTERIOUS ENERGY
Dark Energy is known as “unknown energy” which is a hypothetical concept to determine the accelerating the expansion of a universe. Dark energy contributes 68.3% of the total energy in the present universe. Other is ordinary matter which contributes 4.9% of the total energy and mass-energy of dark matter contributes 26.8% and remaining contributes (protons and neutrons and photons) very small amount of energy. We find the existence of dark energy indirect but which comes from independent sources these are: 1. Distance measurements and their relation to red shift, which suggests that the universe is expanding. 2. There is additional energy which is not a matter or a dark matter to form the flat universe. It can measure from a large scale of wave patterns of mass density in the universe. 3. Dark Energy never emits or absorbs light and these are composed by Baryons or Non-Baryons matter. (REMEMBER): Baryonic matter composed of protons, neutrons and electrons a
