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 – (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
