Dark-Matter StarsBy Jim Hartsell, Dec. 29, 2010.

The universe is 23% dark matter, 73% dark energy, and 4% atoms (regular matter). Dark matter is neutral with no positive or negative charge. It cannot form atoms as regular matter does. It does not interact with regular matter. Dark matter particles are constantly passing unimpeded through our bodies, and even Earth. However, they ARE affected by gravity. They are being called Weakly Interacting Massive Particles (WIMPS).
There is an interesting possibility that the initial matter in the universe was only dark matter, that the very first stars were fueled by dark matter, and that regular matter (atoms) was first formed inside these stars.
Dark matter is its own anti-particle, and when forced together inside the star, produces the energy that caused the star to shine.
This to me is very aesthetically pleasing.
