In the Augest issue of Astronomy on page 57, it says the contents of universe is: 70% dark energy; 25% dark matter; 4% free hydrogen and helium; .5% stars; and .5% for everything else.
Is the 4% correct? I thought intersteller matter (free hydrogen/helium) was only about 10% of the physical mass and stars 90%.
