Our planet will eventually become a vast desert, similar to today's Mars. For hundreds of millions of years, the Sun has been heating up, getting brighter and hotter, and will continue to do so. In about two billion years or more, temperatures will become so hot that the oceans that make Earth habitable will evaporate. The whole planet will turn into an endless desert. As scientists predict, in the next few billion years, the Sun will turn into a red giant and completely swallow the Earth - the planet will definitely come to an end.

Thermal imagers are able to identify an object by the heat it radiates. And polar bears are experts at keeping warm. Thanks to a thick layer of subcutaneous fat and a warm coat, bears are able to endure even the coldest days in the Arctic.

9. It takes light 8 minutes 19 seconds to travel from the sun to the earth.

It is known that the speed of light is 300,000 kilometers per second. But even with such dizzying speed, it will take time to overcome the distance between the Sun and the Earth. And 8 minutes is not so much on a cosmic scale. It takes 5.5 hours for sunlight to reach Pluto.

10. If you remove all the interatomic space, humanity will fit in a sugar cube

In fact, more than 99.9999% of an atom is empty space. An atom consists of a tiny, dense nucleus surrounded by a cloud of electrons that proportionally occupy more space. This is because electrons move in waves. They can only exist where the crests and troughs of the waves add up in a certain way. The electrons do not stay at one point, their location can be anywhere within the orbit. That is why they take up a lot of space.

11. Gastric Juice Can Dissolve Razor Blades

The stomach digests food thanks to caustic hydrochloric acid with a high pH (hydrogen index) - from two to three. But at the same time, the acid also affects the gastric mucosa, which, however, is able to quickly recover. The lining of your stomach is completely renewed every four days.

Scientists have many versions of why this happens. The most likely: due to huge asteroids that have affected its course in the past, or due to the strong circulation of air currents in the upper atmosphere.

13. A flea can accelerate faster than a space shuttle.

Flea jumps reach breathtaking heights - 8 centimeters per millisecond. Each jump gives the flea an acceleration that is 50 times the acceleration of the spaceship.
