How can we become invisible?

                          How can we become invisible?

I am no big fan of the harry potter series. But I am a science enthusiast, and today I am going to tell that is there any possibilities of becoming invisible. Well yes, there are possibilities but little bit critical. The best way to become invisible is to make our refractive index equal to the air or surrounding. SHOCKED? Yes, this is the only way we can become invisible. But does this work?

The working is very simple. To understand this we need to understand the working that how we are able to see the things. We see things because they reflect light from a source to our eyes which then makes an image of the object. If we stop this process, we can get invisible. Now the question arises that how we ever gonna stop the reflection of light. We can not stop the natural phenomenon, but we can stop the light falling on us. If we make our refractive index equal to air, the light ray falling on us will go though us, instead of reflecting back. 

The scientists around the world have been looking to make this happen. And to your surprise, some of them have also succeeded in this. Two scientists have made a gown that can make the light diffract around the body instead of reflecting back to the viewers eyes. 

This advancement have many plus points, like for security reason , the whole army can go undetected. An army of ten soldiers will be enough for the 3rd world war. 

Along with this, if this technology goes in the hands of terrorist, no one will survive. The terrorist will take and plant bombs like buying apples. 

But overall, this technology is not so far and is to arrive soon. Cause in science, "Today's dream is tomorrows reality"..........
