Where the hell do you learn your Science Chris?? Star Trek!?!
Quote: "Yes. That's due to light entering another material and being refracted because it moves at a different speed."
Particles reacting are doing so on the atomic level, light is simply a form of radiation from materials; there are very many spectrums that can be altered at different levels, as we're talking about altering light at the human visual RGB level; my example showed that the simple interaction of faster moving atoms is capable of warping the trajectory of the radation of light within that given point.
Gravity again is just another form of radiation from particles; i've never heard of 'gravitons' outside of science TV shows, because they're not REAL. Anyone who has studies super string would already know that; because the determinate of gravity is based on Gravity Field = Density*Electron(/Proton:Electron)
Unlike standard radiation that -> Extends From, Gravity is an Atomic Magnetic Field which <- Pulls Towards.
Everything in the universe has an Action-> and Reaction<- force.
The difference in weather something escapes to is cannot escape from a particle is simply the Density and Electron structure of the given particle.
It doesn't take massive amounts of gravity to prevent this and it doesn't have to happen on a HUGE scale like a sun. You cloak would basically just have to be the exact structure where light cannot escape it (but to provide it invisible also not pull it in).
Question for such a thing doesn't become
How much gravity would that take? but How much density and power would it require?
Quote: "The point is this: if you had an invisibility cloak, it would never work from more than one specific angle."
Bollocks, it would work from any angle even if it was just using refraction prisoms... the point is more would it display the CORRECT refraction angle to render it invisible ot just make you look like a Chameleon with a cold?
As i've said; do your damn homework about this stuff first. THEN take part in the conversation in debunking it when you can come up with an iron-cast debunk.
I can't give you a simple sphere example of what the coat does for the simple reason; it depends on alot of factors what it would do.
You want a good example of how it would look, check the screenshots of the dawn demo and look at her wings.
Notice how the light passes though them but as bits forming a pattern but changes with the background. The jacket works something like that; in order to fully explain it I would have to write up a shader for it and show exactly how it works.
But as I said it isn't going for !!INVISIBLE!! it is just dynamic camoflage. I dunno how many more damn times I have to say that.
