Truths About Our World, Which Turned Out To Be Not Truths At All

Human knowledge about the world is constantly changing. For example, it was recently considered that there are 4 oceans on Earth, and now everyone knows that 5. In the bustle of everyday life, we do not follow how science develops, and yet all the information that we once accumulated is rapidly becoming obsolete.

Planets do not rotate around the sun.

At school, we are taught that the Earth revolves around the Sun, but this is not quite so. All celestial bodies rotate around a common center of mass, which is also called the barycenter. The barycenter is usually closest to the object with the largest mass. In the case of the Earth and the Sun, the center of gravity will be very close to the center of the Sun. But if we take Jupiter and the Sun, then their barycenter will already be outside the Sun, because the mass of Jupiter is 318 times the mass of the Earth.

Spartans did not throw children off a cliff

The textbooks on the history of the ancient world wrote that the Spartans were so severe that they threw frail and ugly babies into the abyss. The authors referred to the ancient historian Plutarch. But not so long ago, archaeologists have disproved this myth. They excavated the Apothets Gorge, but they found only the remains of adults between the ages of 18 and 35. The researchers concluded that the bodies belong to criminals and prisoners.

In the heat of the dog, the tongue often protrudes, so many have decided that it is they who sweat. In fact, the dog’s sweat glands are on the  paw pads . However, the protruding tongue really helps the animals to cool due to the saliva evaporating from it.

Calling Everest as the highest mountain in the world is not entirely correct: it is the highest point on the planet. And if we measure the “growth” of the mountain from the foot, then the leader will be the volcano Mauna Kea in Hawaii. Its height from the base, hidden on the ocean floor, reaches more than 10 km. And above sea level, it rises just 4.5 km.

Antique statues are not white

We used to see the ancient statues of snow-white, but they were not always like that. Once the archaeologists Ulrika Koch-Brinkman and Vincenz Brinkman found traces of paint in the folds of the tunics of the ancient gods and suggested that the sculptures were originally colored . With the help of X-rays, infrared and ultraviolet radiation, scientists have confirmed their guess. Then they reconstructed the statues in their original form. It turned out unusual and, frankly, “discolored” ancient heroes looked somehow nobler or something.

For some reason, it is believed that lightning does not hit twice in the same place. However, scientists William Valin and Philip Cryder from the Institute of Atmospheric Physics at the University of Arizona have refuted this myth. They studied videos with thunderstorms in the city of Tucson over the summer of 1997 and found out that out of 386 lightning bolts, 136 hit the same spot 2 or more times .

The famous Mickey Mouse, who brought fame to Walt Disney, was painted by another artist, Ab Iverx . Hit character had a predecessor – rabbit Oswald. His Disney and Iverks created together, but because of the cunning contract drawn up by the customer, they lost their rights to it. Initially, Mickey was very much like Oswald and spoke in the voice of Disney himself.

For a long time it was believed that the chameleon changes color with a view to disguise. But now scientists are sure: the coloring of an animal depends on its mood . When a chameleon is angry, its color darkens, and light colors can serve to attract a partner.

Draft is not the cause of the disease

An open window will never be the root cause of the disease. Why does draft have such an insidious reputation? The fact is that because of hypothermia, there is a decrease in local immunity, which, in turn, leads to vascular spasm. But hypothermia alone is not enough to get sick – there must be some kind of pathogen (most often a virus, less often a bacterium). And pathogens with great pleasure breed in unventilated areas with dead air. That is why drafts not only do not bear serious harm, but are also good for health.
