When will the sun go out? Detailed answer Directory / Big encyclopedia. Questions for quiz and self-education Did you know? When will the sun go out? The very posing of such a question may raise doubts. Won't the sun shine on us forever? No, unfortunately it is not. We know that the Sun is an ordinary star, and any star goes out sooner or later. At one time, scientists believed that the Sun was slowly cooling down or "burning out". However, now we know that if this happened in reality, then his energy would be enough at best for several millennia. It is obvious that this is not the case. If the Sun does not "burn out", then what happens to it in this case? Modern science has confirmation of the theory, according to which the energy emitted by the Sun is released as a result of reactions occurring in its depths. Their essence boils down to the fact that under the influence of monstrous temperatures, hydrogen atoms, when combined, form the nuclei of helium atoms. A similar reaction underlies the action of a thermonuclear weapon - a hydrogen bomb, the explosion of which, as you know, releases an enormous amount of energy. So the question boils down to how long the sun's hydrogen supply will last. If we assume that the process of "burning out" hydrogen will continue to proceed at the same pace as now, then the Sun will shine for another 150 billion years. As a result of this process, the mass of the Sun will decrease by only one percent. Therefore, there is no reason to worry that it may go out even in the very distant future. Author: Likum A. Random interesting fact from the Great Encyclopedia: Who first explored the North Pole? The two polar regions surround the Earth's geographic poles. They are called the North Pole and the South Pole. The northern polar region - the Arctic was of interest to people since ancient Greece, and maybe even earlier. It is believed that the famous Greek explorer Pitis was the person who discovered the Arctic. In the IV century BC. e. he set sail from the Mediterranean north to the border of the Arctic region. Perhaps northern peoples (for example, those who lived in Norway and Britain) sailed to the northern seas before, but written evidence proving this has not been preserved. In the 1903th century the great exploration of the North and the Northeast began. Many researchers reached the Arctic region and explored it. These studies continued until the beginning of the XNUMXth century, and in XNUMX an expedition headed by the Norwegian explorer Roald Amundsen set off to the pole. Scientists intended to explore directly the North Pole. American Admiral Robert Edwin Peary led an expedition across the ice of the polar sea from a base located on the northern coast of Ellesmere Island. On April 6, 1909, he became the first person to reach the North Pole. The first flight over the North Pole, started from Svalbard, was made by the American explorer Richard E. Beard on May 9, 1926.
