invisibility

Invisibility refers to the ability of an object or person to become unseen by the human eye. This is typically achieved through technology or natural phenomena that manipulate light, such as bending, absorbing, or redirecting it around an object, effectively making it disappear from view. Scientific research explores various methods, including metamaterials and advanced optics, to develop practical invisibility cloaks. While complete invisibility remains experimental, these advancements aim to control light interactions to conceal objects, potentially revolutionizing fields like defense, privacy, and imaging.
