Hi...

Wikipedia says that only five percent of the universe is matter that we know.... Can anyone tell me a paper where the percentages of visible matter, dark matter and dark energy in the universe are given?

Any of the papers from the WMAP science team will discuss this. However, an introductory cosmology text book is probably a better place to go.

The numbers are easier to find here. "Baryonic" means normal matter.
