is invisibility possible ??? in future ??

Answer 1

To answer your question it already exists, but not in the way you think:

I've read that if you could bend the light around you so that people saw past you you also would not be able to see out as the light waves would pass by you uniterrupted which for a person would make a cloak questionable.

Answer 2

it is certainly the question is to find a perfect black color
we are able to see everything because of the formation of image on fovea centralis on our retina
the image is made with the help of light
it is a universal fact that black object absorbs all the light( if it is perfectly black which any object isnt)
if light falls on a perfect black body then certaily no light will reflect and result in invisibility
