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

Big Big Bang Challenges

Upon careful consideration, the cosmological theory of the origin and structure of the universe begins to crack at the seams.

Take a look at the starry night sky. How did all these countless stars and planets come about? Most modern scientists are likely to answer this question by referring to one version of the Big Bang theory. In accordance with this theory, at first all the matter of the Universe was concentrated at one point and heated to a very high temperature. At some point in time, an explosion of terrifying force occurred. In an expanding cloud of superheated subatomic particles, atoms, stars, galaxies, planets gradually began to Continue reading
