If all mass in the universe  were converted to energy (E=mc^2), how much would 
the energy of the universe increase in percent?  This should be roughly the 
same fraction of energy that condensed into matter in the first instants after 
the big bang. 

A related question would be how much has the fraction of energy/mass changed 
from the period after inflation until now?  Stars are eating up the mass.
