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
For centuries, man has sought to unravel the mystery of the great world “order” of the Universe, which the ancient Greek philosophers called Cosmos (translated from Greek – “order”, “beauty”), in contrast to Chaos, which, they believed, preceded the appearance of Cosmos.
The first natural science ideas that came to us about the Universe surrounding us were formulated by ancient Greek philosophers in the 7-5 centuries. BC e. Their natural-philosophical teachings relied on previously accumulated astronomical knowledge of the Egyptians, Sumerians, Babylonians, Aryans, but were distinguished by a significant role of explanatory hypotheses, a desire to penetrate the hidden Continue reading
Asteroids are through and through cold, lifeless bodies. In the distant past, their bowels could be warm and even hot due to radioactive or some other heat sources. Since then, they have long cooled off. However, the internal heat never warmed the surface: the heat flux from the bowels was imperceptibly small. The surface layers remained cold, and only collisions from time to time caused a short-term local heating.
The only constant source of heat for asteroids remains the Sun, distant and therefore heating is very bad. A heated asteroid emits thermal energy into outer space, and the more intense it is, the stronger it is heated. Losses are covered by the absorbed part of the solar energy incident on the asteroid.
If we average the temperature over the entire illuminated surface, we get that for asteroids of a spherical shape, Continue reading
