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.

 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.

Artificial leather for touch emulation 15.04.2024

In a modern technology world where distance is becoming increasingly commonplace, maintaining connection and a sense of closeness is important. Recent developments in artificial skin by German scientists from Saarland University represent a new era in virtual interactions. German researchers from Saarland University have developed ultra-thin films that can transmit the sensation of touch over a distance. This cutting-edge technology provides new opportunities for virtual communication, especially for those who find themselves far from their loved ones. The ultra-thin films developed by the researchers, just 50 micrometers thick, can be integrated into textiles and worn like a second skin. These films act as sensors that recognize tactile signals from mom or dad, and as actuators that transmit these movements to the baby. Parents' touch to the fabric activates sensors that react to pressure and deform the ultra-thin film. This ... >>

The attractiveness of caring men 14.04.2024

The stereotype that women prefer "bad boys" has long been widespread. However, recent research conducted by British scientists from Monash University offers a new perspective on this issue. They looked at how women responded to men's emotional responsibility and willingness to help others. The study's findings could change our understanding of what makes men attractive to women. A study conducted by scientists from Monash University leads to new findings about men's attractiveness to women. In the experiment, women were shown photographs of men with brief stories about their behavior in various situations, including their reaction to an encounter with a homeless person. Some of the men ignored the homeless man, while others helped him, such as buying him food. A study found that men who showed empathy and kindness were more attractive to women compared to men who showed empathy and kindness. ... >>

Contact lenses with blood sugar control 15.04.2017

A group of scientists from the US state of Oregon conducted a study, as a result of which they found out that contact lenses can measure blood sugar levels. Painful sensations at the same time come to naught.

American scientists have been able to develop unique contact lenses with which you can determine the level of sugar in the blood. The fact is that inside the lens, scientists have placed transistors that regulate the performance. It is reported that one square millimeter can fit about two and a half of these sensors. With the help of Wi-Fi or bluetooth, data can be sent to the device, which will provide a painless procedure for determining this component in the blood. Scientists have previously said that a tear can "tell" about the level of this substance.

Currently, this type of contact lens, which can measure blood sugar, is at the testing level and will not go on sale soon, but now the studies are showing positive results.
