Please educate me on light/matter

[Pengwuino]

"Light can be condensed into matter"
"matter is a state that energy is in"

Someone please tell me those are wrong/right and explain :)

What do you mean by "condensed"? Photons, (light ?) are adsorbed by "matter" Is that what you mean?
Yes, Matter is a form of energy.

Someone please tell me those are wrong/right and explain :)

Really your question is so open ended that it is nearly impossible to answer. If you were to enter into a formal course of study you would still be getting answers to those questions after years of work, you seem to want cliff notes, or the 25 words or less version of a entire physics course.

Well actually some guy said those are true and I am just thinking "no no no, that's wrong" but i can't really figure why there wrong. He said light can be condensed and acted like it can be condensed just like you condense steam into water or air into LN and so on and so forth. Second one i was arguing that atoms have energy associated with them and that atoms "have energy". He said "no, Energy comes in the form of atoms" basically.

Well, a pair of sufficiently energetic photons can fom an electron-positron or other particle-antiparticle pair. But condensation really isn't the right word to describe this process. It's usually reserved for the specific case of a gas turning into a liquid.

If you think it's worthwhile arguing, you can ask your friend to describe an experiment that would distinguish between his statmenets and yours. His statements are really pretty vague, they don't actually say much.

I don't understand why there are all of these "is light matter" debates. By definition matter has 2 things: mass and volume. Light has neither. End of story.

There is no "debate" right now. You're responding to a thread that had its last activity in 2005!
