Why is there no life on the moon?

Now that man has carefully explored the surface of the moon, he has learned a lot of interesting things about it. But the fact that there is no life on the moon, man knew long before he reached the moon. There is no atmosphere on the moon. Astronomers have established this because there is no twilight, no sunset on the Moon. On Earth, night falls gradually because the air reflects the sun's rays even after sunset.

On the moon, it’s completely different: it was just light, and at one moment darkness came. The absence of an atmosphere means that the Moon is not protected from any solar radiation. The sun radiates heat, shines radio waves. Life on Earth depends on this heat and light. But the Sun also emits harmful radiation. Earth's atmosphere protects us from it. And there is no atmosphere on the Moon that could absorb this harmful radiation. And all the sun's rays, useful and harmful, safely reach the surface of the moon. Because there is no atmosphere, the Moon's surface is either excessively hot or excessively cold.

The moon rotates, and the side that is turned towards the sun becomes very hot. Temperatures can reach over 150 degrees Celsius. This is hot boiling water. A hot lunar day lasts for two weeks. It is followed by a night, which also lasts two weeks. At night the temperature drops to 125 degrees below zero. This is twice as cold as the temperature that is observed at the North Pole. Under such conditions, none of the forms of life known on Earth can exist.

Random interesting fact from the Great Encyclopedia:

Is there any weight near the air?

Most of us think that air is "nothing", but air is clearly "something" if it is made up of certain gases. Gas does not have a definite size or shape, but it occupies space. The vast ocean of air that surrounds the earth and stretches upward for miles is pulled and held together by the earth's gravity. Therefore, air has weight. And since air is all around us, it adds weight to any object it fills.

For example, a volleyball contains a small amount of air. If you weigh two of these balls, one inflated and one deflated, you will find that the deflated ball is lighter. The weight of the air creates pressure. Air presses on your whole body from all sides, like water if you are at the bottom of the sea. A huge mass of air presses very hard on the Earth, and the pressure at the same time is about one kilogram per square centimeter.

A kilogram is the weight of a column of air with a base area of 1 square centimeter and a height equal to that of the atmosphere. The area of your palm is approximately 77 square centimeters. Imagine that a weight of 77 kilograms is placed on your palm! The reason you don't notice this is because the air under your hand pushes with the same force as it does from above. And the air presses on your head with a force of 270 kilograms, but it does not flatten you, because there is air inside your body that balances the pressure of the outside air.

The higher you climb (for example, to the top of a mountain), the less air above you, the less pressure. At an altitude of 6000 meters, the pressure is approximately 0,4 kilograms per square centimeter. At an altitude of 3000 meters - 0,7 kilograms per square centimeter. If you could go up to a height of 100 kilometers, you would find that there is almost no pressure.

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. ... >>

Chocolate that doesn't melt 09.01.2016

Barry Callebaut claims to have created a technology that beats the melting of chocolate. And they have already begun to produce miracle bars that retain their shape and consistency at temperatures up to 38 ° C - 4 ° C more than ordinary chocolate can withstand.

The company's management instructed its specialists to develop heat-resistant chocolate in order to further develop new markets. The new chocolate is planned to be sold in countries with a warmer climate - in the Middle East, Asia and Africa. The company notes that chocolate is less popular in these regions precisely because of the high cost of delivery. Meanwhile, among the advantages of heat-resistant chocolate are just simplified conditions for transportation and storage.

The idea of making chocolate unaffected by heat is not new; similar technologies have been developed by several companies for decades. For example, Hershey, a company that has been selling "tropical bars" since World War II, says its heat-resistant chocolate will go on sale within two years.

And Nestle experts believe that it is possible to create chocolate that can withstand heat up to 40 ° C. As early as 2012, Cadbury's laboratory staff developed a chocolate that retains its shape at this temperature for more than three hours.

Hershey previously announced plans to launch chocolates infused with the amino acid L-theanine found in green tea. This decision was made after a study that proved that dark chocolate and green tea - the perfect combination to increase concentration.
