Thats interesting, but if you read the articles, its not really as amazing as I thought it might be.
Though it does proove that something could go faster than light, a vessel like a space craft trying to go faster than that or even getting to that speed would be impossible to do so because of all the other laws, so in reality, it still stands. You couldn't go faster than light.
And its true, he said Light...
So because the red goes faster than some other wave patterns, its still as FAST as light is, so the theory still stands as correct
No object or anything will be able to go as fast as that. No way.
I doubt it would affect the holographic discs to do what you suggest. Those articles have scientists using very complex equipment to get these results. Its not something they could just do like that.
