Web24 de ene. de 2014 · WMAP determined that the universe is flat, from which it follows that the mean energy density in the universe is equal to the critical density (within a 0.5% margin of error). This is equivalent to a mass density of 9.9 x 10 -30 g/cm 3, which is equivalent to only 5.9 protons per cubic meter. Of this total density, we now (as of … http://labsci.stanford.edu/images/Atomic-Structure-T.pdf
