Humanity has learned to send spaceships to other planets, has created nuclear technology and global communication. Sometimes people begin to think that they are the masters of the universe. However, there is a hidden world right around us, invisible to us. We live in a world of invisible phenomena, because our eyes are able to see only the visible spectrum.
The world around us is made of energy, but we cannot touch or see it. Instead, we use technology to capture energy in a spectrum invisible to us: electromagnetic fields, ultraviolet, infrared rays.
We know about the existence of the wireless Internet, because we use it in our work, but we do not see how it entangles our space.
Physicist and mathematician of the 17th century Isaac Newton, during his experiments in the field of optics, was the first to introduce the concept of spectrum, which came from the Latin word "vision". He described a rainbow band that appears after sunlight passes through a glass prism. He realized that there are phenomena that are invisible to our eyes.
There are different colors that we, unlike some animals, cannot see. For example, bees see ultraviolet light, and they use this ability to distinguish flowers. Last year, the journal Science published a study that said bees and flowers can communicate with each other using magnetobiological radiation. Birds and other animals are able to capture the Earth's electromagnetic field, orienting themselves on it during migration or hunting.
Unlike insects and many animals, the human eye can only pick up a limited electromagnetic spectrum and wavelength of light.

See the invisible
Animals can see many things invisible to us and use this for survival. Through magnetoreception, many living things sense magnetic fields to determine direction, height, and location. They use them for orientation and migration. Magnetoreception is inherent in birds, turtles, foxes, and even bacteria.
One study observed foxes hunting mice. To the surprise of scientists, even during the hunt, foxes were guided by the earth's magnetic field. They attacked prey from a certain magnetic direction - from the north-east. When they used this direction, they almost always managed to catch prey.
Some migratory birds, such as robins, appear to be interfered with by the electromagnetic "noise" of instruments, according to a study in the journal Nature. During the experiment, the captured robins were forced to find a way out of the funnel-shaped cell.
When the birds were exposed to electromagnetic interference created by scientists, they lost their orientation: they flew in different directions and could not find a way out of the cage. After being protected from interference by a Faraday cage, their internal compass started working again and they found their way out easily.
Scary ultraviolet
Reindeer and other migratory animals avoid areas where power lines pass. According to scientists, this is because they see ultraviolet light. It is not visible to humans, but animals probably perceive power lines as long intimidating ribbons that emit bright light, where periodic flashes occur. Unsurprisingly, they try to stay away from them.
Oversensitive perception
Individuals are able to see what is hidden from the majority.
In 1923, the artist Claude Monet underwent cataract surgery. Some believe that as a result of this operation, he began to distinguish colors in the ultraviolet spectrum and his painting changed slightly. His water lilies took on a blue tint - this was his perception of the world due to the ultraviolet color.

Concetta Antico is an Australian artist with a rare genotype. She is a tetrachromat: she has a fourth receptor in her eyes that allows her to see 99 million more color shades than other people. Her cheerful colorful paintings reflect the bright kaleidoscopic world that she sees.
The ability to see the aura
Of course, there are those who claim to see the energy emitted by the human body - the aura. The aura meant radiation around the human body, this concept is often associated with spirituality. Scientists are skeptical about the idea of an aura. Some believe that the ability to see the aura arises from processes in the human brain that can be caused by synesthesia, epilepsy, or migraine.
Proponents of the aura idea cite Kirlian photography as proof, a technique that allows you to remove electrical charges around objects. These amazing images are reminiscent of what many describe as an aura.
With technological progress and the development of science, we gain the ability to better perceive the wonderful world around us, invisible to our eyes.
