Who are the strongmen? Detailed answer Directory / Big encyclopedia. Questions for quiz and self-education Did you know? Who are the strongmen? These are participants in competitions for lifting and carrying weights over a certain distance. Although this sport is not an Olympic sport, the title of the strongest man on the planet (strongman) is very honorable. Author: Mendeleev V.A. Random interesting fact from the Great Encyclopedia: What are shooting stars? For many millennia, man has observed shooting stars, wondering what they are and where they come from. For some time it was believed that they come from other worlds. Today we know that these are not "stars" at all. We call them "meteors". They consist of a solid body and, moving in outer space, sometimes fall into the Earth's atmosphere. When a meteor passes through our atmosphere, we can observe it as it leaves a bright trail in the sky. This comes from the fact that as a result of the friction of the surface of the meteor on the air, heat is released. Surprisingly, most meteors are very small, no bigger than a pinhead. Some meteors can weigh up to several tons. Most meteors burn up completely in the atmosphere, and only large meteors reach the Earth's surface. According to scientists, thousands of meteors fall on Earth every day, but since most of the Earth is covered by seas and oceans, meteors fall mainly there. We may see a single meteor flying in any direction, but usually we see meteor showers made up of thousands of shooting stars. When the Earth crosses a meteor shower, a huge mass of meteors, falling into the upper atmosphere, heats up, and then we see a "meteor shower". How did meteors appear? Modern astronomers believe that these meteor showers are the remnants of comets. When a comet is destroyed, millions of its particles continue to move in space in the form of a stream of meteors. They move in circular orbits. Every 33 years, the Earth crosses the orbit of such a meteor shower. A meteor that hits the earth's surface is called a meteorite. It falls to Earth due to gravity. In 467 BC, a meteorite was recorded in ancient Rome. This event was considered so important that even ancient Roman historians noted it.
