The beginning of the invisible age

Do you want to be a hero? I know you want to. Everybody dreams to be a hero. If you have a chance to be a hero and you’re given by the gods the power of being invisible, would you accept it? Hell yeah! If I were you, I will accept it without doubt.

The power of being invisible is only made possible in our imagination. You can see it in Heroes and other sci-fi films. But believe or not, with constant research about it, the dream of being invisible has somewhat evolve a little bit.

Did you know that researchers from Germany’s Karlsruhe Institute of Technology were able to make a 3D object invisible? Nah, I’m not joking, this is really true! They made a tiny bump in a layer of gold invisible! The size is 0.00004 inch high and 0.0005 inch across. It’s really microscopic I know, but they managed to make it invisible to the naked eyes.

So how does it work? Let’s start with simple the principle of vision. In order to see things, our retina uses the light of the objects we are seeing. For this object to be invisible, there should be something that bends the light that it reflects and the role of the cloak comes in.

The cloak is a structure of crystals with air spaces in between, sort of like a woodpile, that bends light. Unlike previously invented cloaks that works through 2D objects, this cloak that they were able to make hides 3D objects already.

With endless possibilities and continued research, there is no wonder that someday we’ll just wake up and find out that we can be heroes as well and we’ll have the power of invisibility!
