is this arguments valid ?

MASS and ENERGY
-whereever there are mass , there also energy .
-every energy changes , it will also change the mass .
i/e iron that heated will change the mass .
therefore every energy is mass .

PHOTON , ENERGY , AND MASS.
-Photon is Energy
-photon also particle
-photon is particle that move like electron .
therefore every energy is photon, and every energy is mass .

i see what Einstein Did there

btw, since this thread have changed from about energy, to thread about weird stuff like photon .

how if we do some phun ?

if photon have mass , What happen to the thing that Hitted massively with something that Shotted in the Speed of light ?

if photon have mass , why is we can not place that thingy in a box ?

Boxes not small enough! (Aren't you familiar with the two-slit experiment?)

I'd recommend Feynman's QED… But what you'd get from it is — a headache! (That's what everyone gets from it…

)

photon is wave that interact like particle .

it seems not everyone get a headache from it ..

Any physical system, be it an atom, a ball or the entire universe has a property of mass and a property of energy. The properties are proportional by a factor of the speed of light squared or more precisely, E=mc2. To change a quote somewhat, "Energy is something that matter has--it is not what matter is. (I have height and weight--that does not mean I am height and weight.)"

Some issues discussed in this http://profmattstrassler.com/articles-and-posts/particle-physics-basics/mass-energy-matter-etc/matter-and-energy-a-false-dichotomy/ interesting article include:

--Matter and Energy really aren't in the same class and shouldn't be paired in one’s mind.

--Matter, in fact, is an ambiguous term; there are several different definitions used in both scientific literature and in public discourse. Each definition selects a certain subset of the particles of nature, for different reasons. Consumer beware! Matter is always some kind of stuff, but which stuff depends on context.

--Energy is not ambiguous (not within physics, anyway). But energy is not itself stuff; it is something that all stuff has.

--The term Dark Energy confuses the issue, since it isn't (just) energy after all. It also really isn't stuff; certain kinds of stuff can be responsible for its presence, though we don’t know the details.

--Photons should not be called `energy’, or `pure energy’, or anything similar. All particles are ripples in fields and have energy; photons are not special in this regard. Photons are stuff; energy is not.

--The stuff of the universe is all made from fields (the basic ingredients of the universe) and their particles. At least this is the post-1973 viewpoint.

Btw, heated iron has a small increase in mass because of the added oxygen molecules to the metal and not because of any added energy.

well ...

that are alot of points about matter , energy , and photon .
