   A zero-energy universe has a 1:1 ratio of negative gravitational force   
   to positive force. Gravitons with zero mass could cohere with the field   
   equations of general relative. Gravitons would have a 2 spin and for   
   the sake of simplicity they would constitute the negative force.   
   Photons have a 1 spin and constitute most of the positive force.   
   Estimates indicate that the observable universe has 10^90 photons.   
   Assuming general relativity, quantum gravity, and a zero-energy   
   universe, what is the ratio of gravitons to photons?
