Star evolution

Like all bodies in nature, stars do not remain unchanged, they are born, evolve, and finally “die.” To trace the life path of stars and understand how they age, you need to know how they arise. In the past, this seemed like a big mystery; modern astronomers can already with great confidence describe in detail the paths leading to the appearance of bright stars in our night sky.
Not so long ago, astronomers believed that it takes millions of years to form a star from interstellar gas and dust. But in recent years, striking photographs have been taken of the area of ​​the sky that is part of the Great Orion Nebula, where a small cluster of stars has appeared over the course of several years. In the pictures of 1947. in this place a group of three star-like objects was visible. By 1954 some of them became oblong, and by Continue reading

In search of a peace system

1. Introduction.
The starry sky at all times occupied the imagination of people. Why do stars light up? How many of them shine in the night? Are they far from us? Does the stellar universe have boundaries? Since ancient times, man thought about these and many other questions, sought to understand and comprehend the structure of that big world in which we live.

The earliest representations of people about him are preserved in fairy tales and legends. Centuries and millennia passed before the science of the Universe arose and received a deep substantiation and Continue reading

Quantum Physics and Reality

All modern cosmological theories also rely on quantum mechanics, which describes the behavior of atomic and subatomic particles. Quantum physics is fundamentally different from classical, Newtonian physics. Classical physics describes the behavior of material objects, while quantum physics focuses only on a mathematical description of the processes of observation and measurement. Material material reality disappears from its field of vision. Nobel laureate V. Heisenberg says: “It turned out that we are no longer able to separate the particle’s behavior from the observation process. As a result, we have to put up with the fact that the laws of nature, which quantum mechanics formulates in mathematical form, are not related to the behavior of elementary particles as such, but only to our knowledge of these particles. ” In quantum Continue reading
