In addition to the question of the origin of the universe, modern cosmologists face a number of other problems. So that the standard theory of the big bang could predict…

Galaxies and metagalaxies

In one of his speeches, A. Einstein said (in 1929): “To be honest, we want to not only find out how it works, but also if possible to achieve the goal of a utopian and daring-looking – to understand why nature is such. “This is the Promethean element of scientific creativity.”

Galaxies have been the subject of cosmogonic research since the 1920s, when their true nature was reliably established, and it turned out that these are not nebulae, i.e. not clouds of gas and dust, which are not far from us, but huge star worlds lying from us at very great distances from us. Discoveries and research in the field of cosmology have clarified in recent decades much of what concerns the background of galaxies and stars, the physical state of discharged matter from which they formed in very distant times. The whole of modern Continue reading

Big Bang Scenario

Like any scheme that claims to explain the data on the spectrum of microwave cosmic radiation, the chemical composition of pre-galactic matter and the hierarchy of the scales of cosmic structures, the standard model of the evolution of the Universe is based on a number of initial assumptions (about the properties of matter, space and time) that play the role of original conditions for the expansion of the world. One of the working hypotheses of this model is the assumption of uniformity and isotropy of the properties of the Universe throughout all stages of its evolution.

In addition, based on data on the spectrum of microwave radiation, it is natural to assume that in the Universe in the past there was a state of thermodynamic equilibrium between plasma and radiation, the temperature of which was high. Finally, Continue reading

Comets – Wanderers of the Solar System

Comets – (from the Greek. Kometes – “star with a tail”, “comet”, “shaggy”; literally – “long-haired”), small bodies of the solar system, rotating around the sun in elongated orbits and looking like foggy objects usually with a light clot – core in the center and tail. When approaching the Sun, the tail of the comet increases, formed by gases evaporating under the solar heat.

Comet Hale-Bopp 1996
Presumably, long-period comets fly to us from the Oort Cloud, located on the outer borders of the solar system, in which millions of cometary nuclei circulate.

Comets are shapeless lumps measuring just a few kilometers, consisting of ice mixed with dust particles. Comets move in very elongated orbits, being mostly far from the Sun, where they remain invisible, and Continue reading
