The idea isn't to come up with a value, but a thought system that shows that unless there is an infinite amount of energy, then the universe MUST be finite.
DrGreg, I think I am arguing the opposite side of the same coin. I am saying since there it would take an infinite amount of energy to reach "C" (you can't ever do it) then if we go to .9999999999999999999999999c work the equation equal to the potential energy equation... you should have the...
Point 1 (particle must have mass so the kinetic energy formula isn't equal to zero
Point 2 "The universe is in this case a large 3d volume that has a limited diameter equal to the distance of these two "lightest" particles at their maximum seperation
Point 3 Yes, I understand that gravity...
Ok, I am a mechanical guy, mechanical engineering degree. With an argument with my Engineering physics wife.
1. Imagine 2 particles (lightest particle with any finite mass)
2. separated by the the entire distance of the universe
3. the particles are attracted (due to gravity) to each other...
