Scientists are exploring the possibility of creating real-life invisibility cloaks by manipulating light waves through techniques like refraction and metamaterials. While current technologies can make objects less detectable to radar or thermal cameras, achieving true invisibility to the human eye remains a challenge due to the complexity of bending all wavelengths of visible light without distortion.
