Is invisibility really achieved?

are we really able to bend lighth or its still a myth?

There are solutions for a sphere that bends light in a way that it appears to not be there at all and remains invisible when viewed from any direction. It has a hollow center where an ordinary object may be concealed. These solutions require meta-materials with refraction indices less than 1. Such meta-materials do exist, but currently, require some very special conditions that make them impractical for building something out of.

I have not heard about anyone actually building one of these, but things look promising at least. However, something even remotely resembling a practical invisibility cloak is still a long way away.

You seem to have spilled your jar of question marks.

I can say that the concept of invisibility is still a topic of ongoing research and experimentation. While there have been some advancements in technologies that can manipulate light and make objects appear invisible, true invisibility in the sense of completely disappearing from sight is not yet achievable. The laws of physics and the limitations of current technology make it difficult to achieve true invisibility. However, scientists continue to explore new materials and techniques in the hopes of one day achieving this feat. So while we may not have achieved invisibility yet, it is certainly not a myth and we should continue to push the boundaries of science to see what is possible.
