in standard math, you're correct, but maybe there's a set of physics/dimensions in which that wouldn't necessarily be the case. (a cube has 6-sides, but if you try to prove it/show it on a piece of paper, you can't... 2-d can't show 3-d detail.) hell, even light "particles" aren't necessarily particles - light can be a wave, depending on how you test it. *it's entirely dependant upon the person viewing the light, how they see it!* or how about this - try to tell me the exact mass *and* location-direction of any particle. you can't, because the simple act of viewing it, *changes the particle*, so it's no longer what it was when you set out to define *the truth* about it...
on a simpler note, let's say you run over a squirrel with your car. you say it was an accident, the guy in his yard says it was intentional, and the squirrel's family claims it was suicide! (yeah, i'm goofin, but trying to make a point.) how about this - you own a green car. is it green? maybe you think so, but i see it as more of a blue, and maybe someone else can't even tell( red-green color blind) now, is your car green to the color-blind person? might be, might be red - your truth is therefore not his truth. you can tell him all you want that it's green, but he can't see that. does that make any more sense?
