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. |
Yes, and these predictions are that 73% of the total energy/matter content of the universe is in the form of dark energy,23% dark matter, and rest goes on the regular matter.Of course, big deviations from this values are possible.
