Scientists don't know much about the mysterious phenomenon known as dark energy, but they do have a picture of what it's doing to the universe, namely, driving it apart.
In what may be the clearest detection of dark energy to date, astronomers at the University of Hawaii looked at microwaves left over from the beginning of the universe some 13.7 billion years ago. The scientists grouped the rays depending on whether they had passed through massive clusters of galaxies or bee-lined to Earthly detectors through areas largely lacking galactic real estate.
In physics and cosmology, dark matter is matter that does not interact with the electromagnetic force, but whose presence can be inferred from gravitational effects on visible matter.
In physical cosmology, dark energy is an exotic form of energy that permeates all of space and tends to increase the rate of expansion of the universe.
