Pro dark matter

Why is 22% of matter in the universe called dark? Because it is not visible in the traditional sense and even in the optical range of wavelengths, as you can see ordinary, luminous matter, which emits or reflects light. Dark matter does not take any participation in electromagnetic interaction. However, it definitely exists.
Another percentage of 74%, as part of the universe is dark energy, the assumption of the existence of which was expressed after observations of supernova and expanding universe. The properties of this substance turned out to be very strange ...
Dark matter formed the galaxies and their accumulations for the first 6.5 billion years after the large explosion, and the second 6.5 billion years prevails dark energy, accelerating the expansion of the universe. According to a number of scientists, without dark matter and dark energy, the emergence and existence of the galaxies themselves, stars in galaxies, star systems, planets and life is impossible.
The author fascinatingly talks about the history of the study of the universe, about the great astronomers, astrophysics and cosmologists, their attempts to recognize or, rather, calculate the fate of the universe.
