So while I was at school the other day I asked my science teacher how fast one would have to be in order to be invisible to the human eye. This is what I got from his answer.........
There is "true" invisibility, that happens when an object that moves faster than the speed of light. However this may not be possible if you know Einsteins theory of relativity ( E= mc2, where c=speed of light). As you move at or near the speed of light light, you mass becomes infinitely large, which means you would need an infinite source of increasing energy in order to keep moving. However Einsteins theory means nothing in comic context.
He told me there is also the ability to be "invisible" to the eye and not be moving at the speed of light. This is an optical illusion-- the object is invisible if it moves faster than the eye/brain can process the images.
Perception - the registration of physically present stimuli.
We only see things that move every 1/24 of a second (we don't really see motion jut the illusion of movement, if it moves.... this is only the persistence of the previous images). If the object moves faster than 1/24th of a second, than it will be invisible to the human eye.
I then I asked him, If someone was running down your street how fast they would have to be in order to be invisible to your eye's. He responded saying in order for something to be truly invisible to the human eye it would have to be moving at the speed of light. The thing that gives us the ability to see things, is the reflection of light upon objects. If someone or something was moving faster than light the would truly be invisible due to the fact that no light could reflect upon them. So yes, If something was running in front of you and they were invisible to your eye they would have to be running above the speed of light, other wise they wee never truly invisible in the first place it would only be an optical illusion.
They don't have to be light speed. Yes, we see the reflection of light upon things, however that doesn't mean our brains work at light speed. All something would have to do in order to be invisible, is move faster than the brain could perceive. You don't have to be going at light speed.

I know, but he's trying to prove that Thor was running lightspeed when he accomplished that feat, but in actuality, he was invisible to the "human eye." That short, little phrase makes all the difference in the world.
He was doing nothing more than running faster than their brains could perceive.
