*At best this is a speculative and unscientific doctrine. Consider what it would take to prove this business? You see existence exists! The mass and energy is here. The existence of the mass is evident during every waking moment. There is no gainsaying that the mass is here. Therefore for this bogus doctrine to hold sway, in the universal sense, we have to postulate that the universe has always been here. And that the universe has always contained precisely the same amount of mass and energy as it does now. This is an unverifiable and unfalsifiable proposition. It is therefore an unscientific proposition that is getting in the way of science. There really isn’t much else to say about this business. Straight logic precludes there being a theoretical proscription on the creation of new mass and energy directly from the fact that these things exist. Sorry this is such a short post. The subject is one of straight and undeniable logic. There truly isn’t anything more to say about this at all.*
Except for one thing. We need to look very much askance at this notion that E=M*C-squared. For one thing we have got to stop looking at these formulas that puny humans come up with as carved in stone. They are approximations only, working more or less between known boundary points. Secondly none of this stuff is proven. When we generate nuclear energy we could write a disclaimer that NO PROTONS WERE DESTROYED DURING THIS PROCESS. There is scant evidence that any matter gets converted into anything else. Rather stored energy, not in the form of mass at all, is liberated from the nucleus. In my working model this amounts to releasing the energy of thousands of compressed electrons, locked up in the nucleus like compressed balloons full of air or akin to compressed springs ready to be unleashed. I am not in any position to prove my working model of matter. But neither is the opposition. Its very odd that we can have all this nuclear energy generation everywhere and no hard evidence for this ideology.
I think that energy and matter are related yes. Because I think that where there are held to be neutrons there is really a great deal of compression, and particularly compressed electrons. But this too is clearly speculation. We want to get away from mere speculation and get some real science done. And for that we have to turf out these sacred cow doctrines choking up the place.
