DARK ENERGY, the greatest discovery of modern astronomy in the last 100 years

Dark Energy it has been discovered using the Hubble constant and measurements of supernovae of distant stars that the universe is not contracting, nor is it static (as Einstein thought), but instead, the universe is expanding, and the expansion is speeding up.

To account for this, a hypothetical form of energy known as Dark Energy has been proposed and is being investigated by leading astrophysicists and cosmologists.

Whether it is a scalar property of space time itself, as proposed through a cosmological constant, or something dynamic, known as quintessence, is a matter of large debate, but current astrophysics places a full 74% of the energy in the universe as being dark energy.
