Ok I really don’t lie when I say Nanotechnology is the next big thing. It can turn you invisible, it can turn you slim, it can leave you ultra young.
For starters watch this video where nanotechnology is playing a crucial role in stealth technology in defense. Most importantly scientist play at the nanoscale whereby we can see a cluster of approximately 10-100 atoms together( depending upon their size).
For sure these scientists work under a very high resolution microscopes in very clean and sophisticated environment whereby a single distortion of an atom can lead to a different result.
Though you are wearing a cloth but you exist physically. The light which is reflected back to the retina of the eye is deflected from its path and that is why you are unable to see.
