Welcome to Gaia! ::

so, that makes me a tough gal! w00t! ^_^ xp

Is it a crime to make fun of stupid character apps? I mean, we all know Ark is getting denied. Why doi peopel all want to be these hulke dout badd a** combat lenaing characters stressed

Ita ******** oxymoron is what it is. And the only itme lightsaber glow black or white is when the crystals are not alighned properly and its about to explode.

Oh and actually, it was silver, I have a sliver/platinum bladed saber. But yeah, the rest of it is bs.

why? What about a white crystals? Or black ones? i thought they came in lots of colors.

For one, black is impossible. You can't make black light, simply because it's not a color. Even if it is about to explode... there's no way to radiate black (like with light), only to make black by absorbing all other colors...and that's exactly the opposite of what light does.

White should be possible, if the right chrystal was found, or by making an uberlong saber with multiple color chrystals producing an equal amount of red, blue and green light (however, such a line up would explode most likely, so white=boom)

"blacklight" is actually kind of purpleish white, the reason they call it blacklight is that it doesn't light things up, exept light colors (making white shirts glow, for example)

And the problem with the solution of the absence is the fact that, to absorb light, you need atoms, you need a material, and with that, a mass. (because emmision and absorbion of light is based on the changing energy levels of electrons in atoms, a change in energy of 2 eV gives a redish color, 2 MeV gives gamma rays I believe)

Anyway, since the blade of a saber is pure energy, it consists of fotons emitted from the saber. Fotons with the enery 2 eV give a red light, but they cannot absorb light...just "show" it. Making a black blade impossible
which would mean a lightsaber, in the core, is a concentrated ray of fotons in all colors (white), on the edge it's of one color (the blade color). Only, since they're concentrated in a beam, you shouldn't see them (because they don't escape in all directions), unless the fotons are reflected by smoke and all, like with a laser (and the edge between the core and blade wouldn't be that sharp, it would likely be a monotone color blade, light with the tone of the blade color)

edit: blacklight is ultraviolet, the works: http://electronics.howstuffworks.com/question59.htm
