Des astrophysiciens ont mesuré la quantité précise de matière dans l’univers
Space-The precise amount of matter in the world will come us explain the essence of black matter, one of the biggest current puzzles in the cosmos.
A team of astrophysicists in the United States has achieved the most accurate measurement ever made of the overall volume of matter in the cosmos, one of the most interesting issues of cosmology.
The reply, published in The Astrophysical Journal this Monday, is that matter constitutes 31.5% (more or less 1.3%) of the overall volume of matter and energy that makes up the universe.
The remaining 68.5 percent was black radiation, a mystical force responsible for increasing the universe and whose presence was derived by the discovery of supernovae in the 1990's.
In other terms, the cumulative volume of matter in the visible world corresponds to 66 million million million million thousand thousand times the density of the Planet, or 66 million billion billion.
