its important not to confuse black matter with dark matter
The Energy distribution in our universe is like this:
0.4% visible matter (stars etc.)
3.6% invisible (dark) -> black matter
23% Dark Matter (that theoretical stuff explaining galaxy rotation)
means its 23% of 'stuff' which causes an odd gravitational pull
70% Dark Energy (That theoretical stuff explaining the expansion)

There is a nice pie chart showing the percentages of various components in the Universe. The actual amount, in terms of an absolute amount, is unknown because we discover more of the Universe as our observational instruments improve.

Can you explain the word "black" and in what context are you using it?
