Dark Matter

 

Dark matter is a idea based on the assumption that the universe must contain about 73 % more mass as that what we are able to see.

 

Some scientist imagine that there exist matter as we cant see.

 

The theory  reach so fare to claim that such 'dark matter' (of course) composed off completely different elements, - and even that the Universe probably is full of whole galaxies made of such dark stuff.

 

Therefore (expensive) space-probes  now are being send out in space searching for proof for  this 'complex' assumptions.

 

Surly it is a fact that the gravitation force is stronger as our calculations, -(based on the known matter) shows. - This article logically shows a more down-to-earth explanation on that 'problem'.
