Apologies for mis-reading. I am not as perfect as you...
As you yourself have suggested, we can experience sensory stimuli through dreams - I can recollect touch and pain. What is pain? Interpretation of nerve stimuli? Electro-chemical reactions within the brain? I am not a neurologist, and don't have the time to research such a field, therefore I can't simply lay my hands on such research. However, it is my hypothesis that "pain" can be triggered by electrical (or electric-like energy from the zat) stimuli directly to the brain. I don't mind if you disagree.
No, I'm not a child. I was attempting to infer that we each accept different levels of "reality" or explanation when we watch sci-fi entertainment. We all choose to interpret our experiences, factual and fictional in terms of our own understanding, so by nature this has to be sequitur... The youngest members of the audience, as I suggested, are happy it is a ray-gun. Perhaps more complex thought examines the possibilities of electricity or similar energy. People like yourself may go further to discuss even more detail. This is mirrored in the views of people having watched films. I tend to go to watch a film, and decide if I enjoyed watching. I don't spend the next three days dissecting in my mind if the plot was 100% logical, or the actors behaved in character, as perhaps a critic may. I accept my own view of what was "good" about the film. I believe this is similar to the current discussion; we are experiencing different levels of expectaction over the "reality" or technical content of the primarily entertainment products. You appear to wish to take this to the ultimate level of understanding at all times, for all shows. I just want to have fun and enjoy myself. This would imply you are saying I should leave the forum, because I am talking about fictional technology in a fictional way, with lots of provisos and assumptions, whereas you are sticking entirely (or not) to factual science.
In terms of the writers, they started the show because they thought it was a good STORY. This is explained in the interviews on the R2 DVDs. As you say, there is a certain amount of technology, since the show is set in the present. But, as you suggest, with such long words, they actually need to keep explaining to the audience what they mean or why things are happening. They obviously recognise they are very close to the edge of comprehension regarding technology for their target audience. Would you have them stop "dumbing down" for the majority, in favour of a technical elite minority. An audience who can truly understand and appreciate the technical effort for authenticity that has gone into the show? This is what you have implied in this and "Making it real" threads.
