Let us suppose that whenever a ray of light strikes a surface, it gets rotated(like in optical fibre cable) and gets off to the other side exactly meeting the path where it was intended to pass through. Even then the 'emptyness' would be visible. Maybe, it would be camouflaged to a much larger extent but nothing can fill that emptiness. So maybe it will look like the representation in predator movie or sort of.

As many have said, it is a question of light refraction. Theoretically it is possible... to test the theory go into a pitch black room with someone, since there is no light bouncing off the said person (or anything else for that matter) you won't be able to see them... now apply this theory to just the person instead of the whole room and the would be invisable. Here's the catch... if no light is present the human eye only picks up black because there is no energy to register on the spectrum... thus the person would not become TRANSPARANT... but the would appear as kind of a shadow... wierd!!!

If you read the article "What makes glass transparent?," you would probably know that glass have electrons that do not absorb the energy of photons in the visible spectrum.
So, for a human body to be invisible, they'll have to heat it to an extreme temperature until it becomes liquid, then cool it. And that's obviously can't be the case. So, the only way to become invisible is to use a new technology which we are unlikely not even close to (or maybe we are!)
Hope that helped!

You guys are waaay over-thinking this. look at someone in the room with you. Close your eyes. Are they visable? It's that simple. He's not asking if you can render a human immune to interaction with light just if they could be made to not be appearant to you. Physics presents a miriad of ways this could be accomplised varrying from narrow beam light frequency amplification to a blindfold

If you can manage to curve the light arond a person and make it continue on the initial path, the person would become invisible

Ya, i read all the references fellow answerers have given and also some more online,.. yes it is possible "as per laws of physics"

Actually the military has made incredible advances, especially against infrared, smoke/heat cannisters, ultimately they intend to develop a suit which is water cooled to surroundings wih fiber optics web which transmits scenary from behind/aside you to the front

Invisible to the naked eye or invisible to all means of measurement?
To the naked eye only requires the bending of visible light around you so that it continues on its original path. We know that light bends (ask any astronomer). It would be a matter of generating a field capable of bending the light and, more importantly, returning it to its original vector.
To make yourself completely invisible is to generate a field capable of bending any energy. Much harder.

now understand what is seeing.light rays coming from a source and hitting(or something else) in to ur eyes and able to see it.if u can stop one from doing this when u are there u can call it is invisibility.theoretically it may be possible(anything can be made possible though)

Go read the Scientific American article last month on metamaterials with a negative index of refraction... want to see through walls?
