How to Become Invisible Without Becoming Blind??!!!

[Tirth Raj]

As we all know we can see because of light ...

So we CAN be invisible

A) If light go through your body ,so no one can see you ..

B) if you can absorbe light .(just assume!!)

 

Let's think A) is possible

then you can not see by yourself 'coz if u let the light go throught your body then light also passes through your eyes without reflecting ... So The whole world is blind to you ,and you are blind to the world!!!

 

and about B) how can single person become a Black hole!!!

 

My question is tell me if there any other possibility to become Invisible without becoming Blind..

and about B) how can single person become a Black hole!!!

 

You would need to be crushed to be billions of time smaller than an atom.

B wouldn't require a black hole, a black piece of paper absorbs most of the light incident on it but it not a black hole. You wouldn't be invisible in the traditional sense as your outline would still be there.

 

The problem here is that A isn't really feasible at the moment, if it was done with a suite you wore then you could also imagine some technology that displayed what your would have seen into your mind and replacing the photons used to create the image with another light source.

[Strange]

I missed the context of (B). If you absorbed all light you would not be invisible but perfectly black.

 

You might want to look into metamaterials: https://en.wikipedia.org/wiki/Metamaterial_cloaking

[Sensei]

If you would be covered by material that only absorbs photons, and not release them, it would quickly heat your body to the level you would die because of life threatening temperature.

 

Black materials, are absorbing photons in visible spectrum, 400 nm to 700 nm wavelength, but release photons at IR and microwave range.

 

See how Top Gear made "invisible" car:

You can also do C) Guide the light around yourself, for example with a set of mirrors, so that whoever is looking at you will see what's behind you, instead of seeing you. This method works for "magicians" although it can only work from a certain angle.

By the way air around us is invisible. So lets assume we are made up of any one gas only (e.g oxygen , hydrogen etc) and the density of our body(made of air) is very high but it is still gas( not liquid or solid) and our body is voluntary in action. It is hard as a solid object that it does not get blown away like air. So can we be invisible?
