Our universe exists since 13 800 million years. It has about 70% of dark
energy responsible for the accelerated expansion of the universe today,
26% of dark matter component mainly in galaxies and 4% of the atoms making
up the visible matter including ourselves.
The turning point made recently in the understanding of dark matter (warm
dark matter) provides a essential simplification in the formation process
and evolution of galaxies in agreement with the observations.
In addition, the latest available data on the evolution of the cosmos and
the primordial inflation determine the two fundamental numbers of the
origin of the universe -the amount of germs of the density of matter and
space-time (the primordial gravitons) -measurable today by the fossil
microwave radiation remained intact since the universe was 300 000 years old.
Quantum mechanics plays an essential role in the understanding of the
Universe. Theory and cosmological observations, galactic black holes and
sterile neutrinos must be thoroughly and carefully examined.
