If this was April 1st...

...you'd think the two acronyms had been made specifically to wind people up but not it would seem:

Dark matter is shown in blue, ordinary matter is coloured pink

The latest astronomical observations suggest that dark matter makes up some 23% of the Universe. Ordinary matter - such as the galaxies, gas, stars and planets - makes up just 4%.
The remaining 73% is made up of another mysterious quantity; dark energy, which is responsible for speeding up the expansion of the cosmos.
According to one model, dark matter may be comprised of exotic sub-atomic "stuff" known as Weakly Interacting Massive Particles (WIMPS).
Others hold that the dark substance consists of everyday matter, rather than some elusive sub-atomic particle. However, this ordinary matter, referred to as Massive Astrophysical Compact Halo Objects (MACHOS), happens to radiate little or no light.
A powerful physics experiment, the Large Hadron Collider, which is currently under construction on the French-Swiss border, could shed further light on this question after it begins operating later this year.
