As science advances laws can change.
----------------------
The Law of Conservation of Energy is often referred to as the Principle of Energy Conservation and otherwise as the First Law of Thermodynamics. It is so firmly established that it has triple foothold in governing how we build our picture of the scientific world. We shall not question its authenticity. Indeed, all you need to accept is that one cannot take energy from nowhere and apply it to our needs, nor, indeed, can Nature create matter out of nothing, given that Nature is governed by her own laws.
-----------------------
I assume that you, the reader, will bear with me as I advance my case, because I assume that you think, as I do, that it is logical for energy, whatever that is, to be conserved and so, if matter can be created from energy and appear in our experiments as if from nowhere, then there is something in that 'nowhere'. I note that scientists now believe that particles of matter, pairs of electrons and positrons, can appear 'as if from nowhere', though they hide all this in their mathematical equations and refer to the phenomenon as 'vacuum energy fluctuations'.
They still pretend that there is no aether but we, in these tutorials, will take a bold frontal position and challenge the views of those who lead would-be theoretical physicists into their own non-aetherial field of confusion. Our sights are on that 'energy' theme and the fundamental question of whether we can ever ourselves mimic Nature by tapping into that sea of energy from which Nature created the protons and electrons that form the matter we see as the universe.
----------------------
... there are three dimensions to physics, namely energy, space (as the cube of distance) and time.
The real challenge of physics is to explain everything in terms of three such physical dimensions, M. L, T, that is mass, length and time being those adopted by tradition, but energy, space and time being those I believe that we should adopt in our ultimate quest to understand all that can become known about fundamental physics.
