http://en.wikipedia.org/wiki/Binding_energy#Mass_Defect<br /><br /><font color="yellow">Because a bound system is at a lower energy level than its unbound constituents, its mass must be less than the total mass of its unbound constituents.</font><br /><br />But the opposite is true for galaxies! Quarks too! Their mass appears to be larger than their constituents as well....
