My answer starts thus: The Radius of the Universe is R^2 = 2/ kp, where k is a Newtonian constant of gravitation, and p is the average density of matter this could be from 1.29E-17 to 5E-30 it seems to change. I'm going to use the first value. Bear in mind that K/2 = 1.08E27. K = was calculated to be 2.16E27. If you let K/2 = variable Y then to find k = 2 * Y. Now multiply the variable Y * p and you arrived at the answer 13.99E9 years. If you have input on this let me know at rvwil66@hotmail.com
