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

Time and Calendar

In very ancient times, people did not have a correct idea of ​​the shape and size of our planet and what place it occupies in space. Now we know that the physical surface of the Earth, which is a combination of land and water, is geometrically very complex; it cannot be represented by any of the well-known and mathematically studied geometric figures. On the surface of the Earth, seas and oceans occupy about 71%, and land – about 29%; the highest mountains and the greatest depths of the oceans are negligible compared to the size of the entire earth. So, for example, on a globe with a diameter of 60 cm, Mount Everest with a height of approximately 8840 m appears as just a grain of 0.25 mm. Therefore, the body, limited by the surface of the oceans, in a calm state mentally continued under all continents, is taken for 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
