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.

You didn't even attempt to answer his question. None of what you just said makes any sense. You totally circumvented the subject.

"Energy" doesn't choose anything. It's a scalar quantity which is assigned to objects. Energy doesn't "use" energy. GRAVITY is not an energy, it's a force with a potential field. Wood doesn't use fire to move freely IT BURNS. Mass doesn't accumulate within energies in motion. Have you even taken physics 101? The most basic theories prove everything you've just said, completely and utterly incorrect.

OP you can think whatever you want when this thread is over. Just don't listen to this guy.

And if you are a troll, god help your soul you're a great one.
