Abstract
Remarkable percentages appear when we study the components of the Universe. These two values, 75 % and 25 %, return very often concomitantly. I wonder if there was no law hiding behind or it would be only a simple coincidence. But we can speak about coincidence when their frequency and their precision curls the regularity. It does not appear to a single place then finds itself in a different place, without relationship with the precedent, but through a set of process in chain of the same nature. In this essay, I am only raising these coincidences, and giving some hypotheses to verify.
