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…

Asteroids

The fact that in the solar system between the orbits of Mars and Jupiter numerous small bodies move, the largest of which are only stone blocks in comparison with the planets, less than 200 years ago. Their discovery was a natural step towards the knowledge of the world around us. This path was not easy and straightforward.

Who, in the era of the discovery of the first asteroids, could have suggested that these small bodies of the solar system, bodies that were often talked about quite recently with a touch of neglect, would be the object of attention of specialists in various fields: natural sciences, cosmogony, astrophysics, celestial Continue reading

The origin of the moon

The history of the evolution of the moon is interesting not only in itself, but also as part of the general problem of the origin of the Earth and other planets of the solar system. Recently, we have learned a lot about the physical and chemical characteristics of the moon. These data were obtained not only from the Earth, but also with the help of spacecraft. For example, the automatic stations Surveyor-5, -6, and -7, which made a soft landing on the moon in 1967 and 1968, made it possible for the first time to determine its chemical composition. Samples of lunar rocks delivered by American astronauts under the Apollo program (1969–1972) and Soviet automatic devices of the Luna series (1970–1976) made it possible to measure their chemical and physical characteristics in detail and determine the age of the moon .

Uranus and Neptune

Uranus is the seventh planet from the Sun in the solar system. In diameter, it is almost four times larger than the Earth. Very far from the Sun and relatively poorly lit. Uranus was discovered by the English scientist W. Herschel in 1781. It is not possible to distinguish any details on the surface of Uranus due to the small angular dimensions of the planet in the field of view of the telescope. This complicates his research, including the study of the laws of rotation. Apparently, Uranus (unlike all other planets) rotates around its axis as if lying on its side. Such an inclination of the equator creates unusual lighting conditions: at the poles in a certain season, the sun’s rays fall almost vertically, and the polar day and polar night cover (alternately) the entire surface of the planet, except for a narrow strip along the equator. Since Uranus Continue reading
