The black matter is a category of hypothetical matter, which does not interact with the so-called ordinary matter, nor with the photons. It is estimated that it constitutes 85% of the matter of the universe. Its assumed presence is detected only indirectly, through its gravitational influence in astrophysical models. It is estimated that it constitutes 85% of the matter of the universe. Its assumed presence is detected only indirectly through its gravitational influence in astronomical models. It is simply said that astronomers have observed several phenomena which can only be explained if space is filled with invisible matter which does not interact with the electromagnetic field, detectable only by its mass and therefore its gravitational field. To the extent that black matter has never been detected directly, alternative hypotheses have been made to explain the above mentioned astrophysical phenomena: for example, that space is filled with invisible matter which does not interact with the electromagnetic field, detectable only by its mass and therefore its gravitational field. To evaluate these counter-sens, one must look at the various points suggesting the existence of black matter: - - **The rotationally curve of galaxies.** The stars of a galaxies.** The starss are arm* A gravitational lens is an optical effect produced by the presence of a massive celestial body between an observer and a source of distant light. This effect, for example, was measured during the Eddington experiment of 1919, which was the first empirical confirmation of Einstein's General Relativity. The presence of a gravity lens around a galaxy allows the estimation of the mass of this galaxy to be estimated. These estimates systematically indicate a mass 6x greater than the mass attributable to the stars and clusters of gases detected in the galaxy. - **The Ball's cluster.** The Ball's cluster is the result of the collision of two clusters of galaxies. The stars of these galaxies, being extremely spaceless, have not been significantly affected by the mass attributable to the stars and clusters of gases detected in the galaxy. - **The Ball's cluster of the Ball.** The Ball's cluster is the result of the collision of two clusters of galaxies. The stars of these galaxies, being extremely spaced, have not been significantly affected during the collision, the stars of these galaxies, the stars of these galaxes, the stars were not much affected during the collision, and most were notThese theories are generally very capable of explaining the first phenomenon (the rotational curve of galaxies). However, they often find it difficult to explain other observations, especially those around the Ball's cluster. The above observations, taken as a whole, can only be explained by the presence of a large quantity of matter, which does not interact with visible matter, does not interact with itself, and is detectable only by its gravitational field.
