You are right. I should said "hope". really what I mean is that we would have a better understanding of why we can't if we know we can't. Like what a photon is. What "energy' "is". That would be cool.-redox and nuke, they both release "energy". But maybe we have to be more precise in the wording. I was assuming more than average understanding because we are using to "prove" something. But "more than average" does not mean "expert" in my case. -I yield to you so I don't confuse him. Thank you for spending the time with us.
