The world is full of mysteries and inexplicable things, and here are a few of these.
Chinese mummy.
The Chinese matron of the Khan dynasty is considered the most preserved mummy. Discovered two thousand years after her death, she is in a fluid that scientists can not repeat.
Her skin is still soft, arms and legs bend in the joints, and the organs and blood vessels remain in an unchanged state that reminds only a recently deceased person. The method of conservation of this mummy is still a mystery.
The skeleton of an alien.
A strange corpse of a creature with hard teeth, a bulging head and scaly skin made many believe that an alien came to Earth.
However, after DNA analysis and other studies have shown that it is a person, many questions have arisen concerning its dimensions, mutations and origin. However, none of the questions were answered and no solution was found.
Black Knight.
In 1958, a strange satellite was first discovered on Earth's orbit.
So the American amateur astronomer Steve Slayton, watching the Moon, noticed on its background an object. The heavenly body quickly crossed the lunar disk and disappeared. Slayton concluded that the object was black, and therefore we do not observe against the background of the dark sky.
So while around the Earth flies it is not clear what, undertaking it is unclear from where. No secret has been disclosed yet. And even if we agree that the "Black Prince" is really just a fragment of a spaceship, the question remains: what ship?
The biggest virus
The largest virus in the world, called Pandora, which is 10-20 times wider than an ordinary virus, was found off the coast of Australia. It contains about 93 percent of unidentified genetic material.
