Energy-Mass Gravity: Universe's Gravitational Pull

[zepp0814]

Hi I was wondering if there is an equation for finding the gravitational pull on on all object in the universe (including that's that are massless)

i am aware of this already but i want to know does a is there a existing method to covert these to the unit Newtons

and also in the equation that was in the wiki, how is the Mass-Energy density expressed in the equation

I don't quite understand the question. Do you mean "from all the objects in the universe"?
