That's the nature of observational and measuring technology, using instruments of WMAP and Planck, and computers from NASA and ESA, fractions can be measured, estimated and calculated.
I don't know how NASA and ESA do their number crunching (and I don't work for them), so you are going beyond what I can answer. You will need someone who worked more knowledge than that I possess.
Anyway you didn't answer my question. Can you answer and explain the same questions you have ask me?
Can you answer that without changing the subject?
And here is claim you have made:
A large part of NASA and ESA works are using computers to detect, measure, calculate their data.
You state the goal of science -
"may be the realization of God, the 100%", how do you come with 100%?
Do you always make up numbers and percentages with no basis on reality?
