I often read, hear and talk about pure energy. What is meant by this? Does pure energy consists of the forces between matter, or the force mediating particles, like the massless photons and gluon? I explicitly don´t mention the W- and Z- particles which are supposed to transmit the weak force, because they possess mass and as such they don´t are a form of pure energy, if what I said is actually pure energy. Maybe an indication that the W- and Z-particles don´t transmit a truly elementary force but a residue force of a force that´s being transmitted by massless particles, like the hyper colour force in Harari´s rishon model, wich accounts for all known subatomic reactions, the decay of the proton (without the ultra heavy X-boson), the presence of only normal matter, instead of equal amounts of matter and anti-matter (in fact there are in this theory equal amounts matter and anti-matter) and it gives a nice and very simple model for the quarks and leptons, wich consist out of only two particles. More economic you can´t make a theory of elementary particles.
This is an every day term, with no meaning for physics. In the Oxford dictionary for "energy" one gets:
- Physics The property of matter and radiation which is manifest as a capacity to perform work (such as causing motion or the interaction of molecules)
In science fiction one might separate zero mass particles, like the photon and the graviton ( if it exists) from massive particles , and call the energy zero mass particles carry as "pure" energy, not connected with mass. In physics it is wrong, as an ensemble of zero mass particles does have mass due to special relativity, by the addition of the four vectors of the photons in the beam, for example. The term "pure" cannot qualify energy.
