Photons: a Definition - Little Killer - 06-02-2007
You know what's cool? Aiming a red, yellow, and blue light at one spot on a wall. . . The light turns white.
Hmmmm. Photons come from the sun! Isn't that cool? And it takes them millions of years to get out of the radiation zone.

I only read half of the first page, so if I'm off topic: Bite me.
The Photon is it's own anti particle because there is nothing that moves faster than the speed of light.

That we know of. We don't know if something actually moves that fast. Maby there's something that moves faster. We just can't answer something like that quickly. . . like Galleleo. Poor guy.
We are talking about antiparticle photons, so you are on topic.
I am not going to stoop down to the level of biting people. . .
That was interesting info Mirinee!

Thanks, and sorry to burst your bubble, but it's true: nothing is faster than the speed of light (oh no, not theories), although I do agree about the white light comment. Try to disperse a white light ray into the spectrum with a prism. It's really pretty. ^^ Not much of a weapon, unless you want to blind/wow someone. Maybe you could somehow get a really really intense light ray.

Whether or not a photon is its antiparticle or not is irrelevant, because it has no practical use anyway, but from what I understand, an antiparticle has the same mass and opposite charge as its particle. A photon has no mass and no charge, hence it fits the description.
So, a photon's antiparticle would also be a photon, travelling at the speed of light, c. I'm all happy with that, but wouldn't it also be travelling in opposite time (what is opposite time?)...or opposite direction? (But then the particle and antiparticle would have a relative speed of 2c, which can't be right).
Why's the speed of light relevant?
Edit: bad wording.

Why does the shade black absorb light? Is it simply because it has an absence of photon-reflective qualities?

OK. Yea blind someone with a red, yellow, and blue lights. I can see it now. . .
"Hey Bob. OH MY GOD! I"M BLIND!"
"EAT MY SPECTRUM OF EVIL!! HA! HA! HA! *cough* HA! HA! HA!"
. . . My humor about light is strange.:alien: Hmmm. If black has no photons, then what is black?!:S *static*

Dark matter? Something that has style, but no substance? I have no idea...

Actually, Little Killer, are you sure you didn't mean black rather than white, when you shine coloured lights onto just the wall? Try it out.
On the back of a cathode-ray tube TV it would be white, and the lights' colours would be yellow, magenta and cyan. I was serious about attacking people with intense "light"/Electromagnetic waves. :O
Things are black because they don't reflect light. It's maybe something to do with their chemical composition. (I'm no chemist either :$). At this time, it's helpful to think of light as waves rather than discrete quanta (photons).
Dark matter as a phrase sounds like something out of science fiction or a video game, unless you mean it very literally.

Darkness is.
That's why it's so good at getting out of the way.

That was bad.
