We bring you the 10 of the greatest scientific myths - you have already heard some of them, or you are convinced of their truth. Let's go through them in more detail ...

Myth #1 - Evolution

The indisputable fact is that there is natural selection in nature, in other words, only the strongest survive. But not always. We can observe in many examples how a seemingly weak and imperfect organism can adapt and survive. Mushrooms, crayfish and mosses. They all adapted perfectly to their changing natural environment and were able to survive without evolutionary development.

Unlike the second group of animals and plants, in which evolution also failed. They simply could not adapt to the changing environment and became extinct. In the context of evolution, therefore, it is more appropriate to mention the word adaptability than to progress.

Myth # 2 - People in space explode

When an unprotected human body is exposed to a cosmic vacuum, it explodes. This myth has its origin in science fiction films. In fact, one can breathe 15-30 seconds into space. Then the lack of oxygen will cause unconsciousness and consequent death by suffocation.

Myth # 3 - Polarica is the brightest star of the northern hemisphere

Polaris is the brightest star only! in the constellation Ursa Minor, for example, such a Sirius is much brighter than a polar bear. However, despite this fact, Polaris is important to us because it shows us the North - for this reason it is also called the North.

Myth #4 - If you lift your food from the ground within five seconds, it will be safe to eat

This statement is utter nonsense. If your food falls to the ground, bacteria will pounce on it immediately. Of course, not all bacteria are bad, as many of them help us strengthen our immune system. However, in many cases, most people follow the rule of taste: if the food is very tasty, they eat it, even if it is on the ground for ten minutes.

Myth No. 5 - One side of the Moon is permanently unlit

No - each side is lit by the sun. This assumption arose from the fact that only one side of it is visible from the Earth (the opposite side). This is due to its tidal-bound synchronous rotation; the time of rotation of the Moon around its axis is the same as the time of orbit of the Moon around the Earth.

Myth # 6 - Cells in the brain can't regenerate - they can't be replaced

This myth has prevailed in the scientific community for quite some time. Until 1998, when scientists at Sweden and the California Salk Institute in La Jolle made the groundbreaking discovery that cells in the brain could regenerate. It was previously believed that the growth of new cells would disrupt brain function, but their study showed that the opposite was true, as they found that learning and memory centers can produce new cells - giving hope to people with Alzheimer's.

Myth # 7 - A coin thrown from a great height can kill pedestrians

This presumption is indeed a film cliché. If you throw a coin from a roof of a very tall building, it gets so fast that it can kill a pedestrian walking on the sidewalk. The truth, however, is that it is not possible; aerodynamics of the coin is not capable of it. So if the coin landed on someone's head, he would only feel a split. And it certainly does not die for this.

Myth #8 - When the meteorite enters the atmosphere, it is heated by friction

When a meteoroid flies into our atmosphere (where it becomes a meteor), it is heated by the pressure of the air, which depends on the current velocity of the falling body. The air pressure causes intense heating, which manifests itself in the form of glow. Many people believe that when a meteor hits the ground (where it becomes a meteorite), its surface is hot. On the contrary, the meteorite is always cold after its impact, sometimes it is even covered with icing. This cooling was caused by a long journey through space, and the heat that warms it as it enters our atmosphere changes its surface only slightly.

Myth #9 - The flash never goes to the same place

Next time, if you want to hide in a place where lightning has just struck, thinking it is safe, remember this article! Lightning strikes the same spot - it's even a very common phenomenon. He mainly chooses tall trees and buildings. In the open, it is very likely that it will repeatedly hit the highest point. Empire State Bulding, for example, has been struck by lightning up to 25 times in one year.

Myth #10 - There is no gravity in space

In fact, gravity works in space. The reason astronauts "float" is because they are in Earth's orbit. This means that they tend to "bounce" off the surface. So they are still falling, but they will never "land". Gravity works virtually throughout the universe. When the shuttle reaches a height of over 400 km in orbit, the effect of gravity is reduced by only 10%.
