How do you rectify these numbers?
The sun is 99.86% of the mass of our solar system and is quite average. [1]
Dark matter is ~27% of the mass of the observable universe. [2]
Are you claiming that exoplanets and asteroids represent 27% of the mass of the universe when a typical G-type star (not particularly massive, by any means) is almost 100% of the mass of our entire solar system?
I'm confused by your assertion - you either have some data I am lacking, have entirely made up your post, or are, yourself, confused.

- mikeash 10y agoNote that 27% is of the total mass and energy, where ~68% consists of dark energy. If you ignore dark energy and just look at matter, dark matter is about 85% of the total. Which is pretty crazy! We have no real idea what 5/6ths of the stuff in the universe actually is!
- fizx 10y agoWe're kind of out on the edge of the galaxy. As you might suspect, dark matter tends to be more dense in the middle of the galaxy. I'll let someone else be more precise: http://cdms.berkeley.edu/Education/DMpages/FAQ/question36.html http://cdms.berkeley.edu/Education/DMpages/FAQ/question36.ht...
