Invisible Universe !!

We can see about only four percent of our universe. About 74 percent of it is accounted for by a mysterious force called "dark energy", while another 22 percent is composed of an invisible matter, termed as "dark matter". It is a big puzzle in cosmology and particle physic, to determine what this missing mass composed of.

In 2005, Astronomers at Cardiff University have discovered a galaxy some 50 million light years away which appears to be made up entirely of invisible dark matter.

About 96 percent of our universe is therefore not composed of "normal" visible matter but of invisible dark matter and dark energy. We know very little about these strange and mysterious forces around us. This is therefore a huge unsolved mystery.
