re: Energy and mass

Everything transforms itself; energy (with the big bang) became matter
I gather that you are referring to the word “matter†as the rest mass energy combined with something solid that is within mass.
From your answer, it seems to me that you believe that energy and mass are totally changeable from one to another, in other words, you seem to feel that there is only one (entity) that exhibits itself either as mass or energy, so that if mass disappears energy takes its place through some type of a conversion process.
How do you distinguish between the potential and kinetic forms of energy that exist within mass?
