More Evidence Supporting Dark Energy

Dark energy and its running mate, dark matter, constitute one of the biggest mysteries in modern day physics. Scientists don't understand exactly what they are or how they work. The role they seem to play in the universe, however, is profound. Estimates are that 74% of the universe is dark energy, 22% dark matter, and only 4% everything we see and touch and know. Dark energy seems to be responsible for the acceleration in the expansion of the universe scientists have recently discovered.

A recent study by a team of astronomers at the University of Hawaii buttresses the case for the existence of dark energy. The team studied microwave radiation before it entered a supercluster of galaxies, and microwave radiation leaving the supercluster. The team also studied microwaves before they entered a supervoid, and microwaves leaving it. Supervoids are exactly what you'd expect-- huge areas of space that contain little or no matter. The obsrved behavior of the microwave radiation fit precisely what it would be if dark energy exists.

We may not know what dark energy is, but it certainly seems to be around.
