No calculation can be done to establish it. Correct?* Correct, that can only be established through observation and experimentation. However if General Relativity is correct and if empty space does contain residual vacuum energy (both those things can only be determined through observation and experimentation but the evidence is piling up that both are correct) then the net amount of energy in the universe is indeed zero.
