| No, we can't make good enough speculations about the universe's total energy, at least no good enough to include in equations.l But we sort of can do something:
1. Get avarage samples of the universe that we can investigate from telescompes. Some areas with suns, others with planets, most with nearly nothing... The amount of samples of each kind have to be correspondance to the ration of the amount we believe there is in the total universe.
2. Measure the energy in those places. Multipy it by how many times we think there are of each sample in the universe. Add it all.
The problem is that we have generalized, estimated and avaraged. These three mathematical workings are part of statistics and have no real correctness. |
