Dark Matter

Dark matter is a mysterious force in the universe. Astronomers are making a dark energy camera to figure out what dark matter really is.

In the mid 1990's astronomers tried to figure out why the universe kept on expanding, they found out that a dark energy was making it expand. It has also been found out that every day the universe starts to expand even faster. It seams that everything we have observed is only five percent of the universe, the rest is made up of dark energy and matter. Astronomers are currently trying to observe the affects of dark energy which accounts for some 70 percent of the universe. But it's not the only dark stuff in the cosmos because roughly 25 percent of it is made up of an entirely separate material called dark matter. Completely invisible to telescopes and the human eye, it neither gives out or absorbs visible light, but its gravitational effect is obvious in the motions of galaxy clusters and individual stars.

Although dark matter has proven extremely difficult to study, many scientists say that it might be composed of subatomic particles that are different from those that create the matter we see around us.There is also a theory on alternate universes because of dark matter. These alternate universes may or may not have dark matter or energy.
