The statement that humans can only see 1% of the visible light spectrum is a common misconception. Humans are capable of perceiving a significant portion of the visible light spectrum, which ranges from approximately 400 to 700 nanometers in wavelength. This range includes the colors we see in our everyday lives.
However, it is true that there are other types of electromagnetic radiation beyond the visible light spectrum that humans cannot see with the naked eye. For example, ultraviolet (UV) radiation and infrared radiation have wavelengths outside the range of human vision. These forms of radiation can be detected and studied using specialized instruments and technologies.
While humans cannot naturally perceive these types of radiation without assistance, it does not necessarily imply that there are legal occupants or hidden entities on Earth that our eyes cannot see. The existence of such entities would require evidence beyond the limitations of our human senses.
It's important to note that scientific exploration and technological advancements have allowed us to expand our understanding of the universe beyond what our eyes can see. Through instruments like telescopes, microscopes, and other detectors, we have been able to explore and study the realms that were once hidden from us, both at macroscopic and microscopic scales.
