What is a UFO?

Their common name is "flying saucers". UFO means "Unidentified Flying Object". Do they really exist? Many books have been written about them and thousands of people say they have seen them, some even claim to have photographed them. And despite what scientific studies show, there will always be people who believe in the existence of UFOs.

A study of reports of flying saucers shows that UFOs are very different from each other. Some people have reported seeing flat-shaped plates, others seeing sphere-shaped plates, cigars, or doughnuts. It seems that the color of the plates is as diverse as their shape. There have been reports of cymbals in almost every color. Some even changed their color while being watched.

People saw that the plates moved at different speeds and in all directions - at an angle, vertically up and down, or in a zigzag. They can hover motionless in the air, make a whistling sound or a roar. When the US Air Force looked into the flying saucer reports, they found that people weren't making things up. Everyone who reported flying saucers actually saw something. But what?

In some cases, "something" turned out to be a probe. Other times it was a satellite, a cloud, a comet, a meteorite, a star, a bird, a planet, or a firework. Among the visions were also reflections of the sun in ice crystals. Many ideas about flying saucers were caused by fireballs.

If the saucers were really spaceships, there would be something in common in all the stories about them. But this is not. And the reason is that people do not see spaceships, but other objects. Therefore, scientists believe that there is no evidence that we are visited, observed or invaded by thinking beings from other worlds.

Random interesting fact from the Great Encyclopedia:

What information can bees extract from the electrical field of flowers?

During the flight, due to the friction of air on the hairs on the body, they accumulate a positive charge on themselves, and flowers usually have a negative charge. It has long been known that due to this difference, the pollen from the flower literally flies to the body of the bee. But recent experiments have shown that bees and bumblebees can extract useful information from the characteristics of electric fields. For example, a changed field of a plant after a visit by one bee may inform another that there is not yet a new portion of nectar in the flower.

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. ... >>

Sleepy cows give sleeping milk 15.12.2015

Milk milked at night helps against insomnia and obsessive anxiety. Korean researchers compared the behavior of rats fed day milk with those fed night milk. It has been found that night milk has a great calming, sedative effect, that after it the animals sleep longer and are less prone to physical activity.

On the other hand, being awake, they explore new territories more actively, which indicates reduced anxiety - roughly speaking, after nightly milk, the rats began to be less afraid. The effect was the same as after diazepam, a well-known sedative and hypnotic drug. (At the same time, milk was given after processing: it was first turned into a powder form, and then the milk powder was diluted with water.)

Day milk can also work as a relaxing agent, but to a lesser extent than night milk. For example, when rats fed day or night milk, or a solution of diazepam, or just water, were placed on a rotating drum and the activity and coordination of movements of rodents were observed, then after night milk rats fell off the drum twice as often as after day milk. (In turn, after diazepam, animals fell off the device twice as often as after night milk.)

A comparative biochemical analysis showed that night milk contains 24% more amino acid tryptophan, which stimulates sleep, and 10 times more of the hormone melatonin, which regulates circadian rhythms, compared to day milk. Obviously, the sleepy state of cows also affects the composition of the milk that they produce at night. On the other hand, according to electroencephalography, there was nothing unusual in the rhythms of the brain after night milk, while characteristic anomalies arose from diazepam, reflecting the sedative effect of the drug.
