help me lrn2physics

Hey /sci/,

How the hell can something be massless? Someone told me that light is a massless energy particle or some shit like that but that can't be possible because in order for something to actually exist, it must be made of something, and that something has to have mass, regardless of how minute it is right? Or is this correct since light is suppose to have duality? Please edumacate me.

lol, stop it. Photons can accelerate or decelerate depending upon what pushes and draws the photon. Find out that info and you can control the flow of photonic energy how you want. Hell, you might even be able to project a new information beam faster and further into space depending upon how you use it. I hope you understand what I mean by push and draw...please tell me you know this function about nature...o.o
