A Philosophic Discussion of the Concept of Mass and the Principle of Isolation
Roger A. Rydin
All known bodies have the property of mass, where a pound of feathers has the same mass as a pound of iron. But both feathers and iron are made of different elements, each of whose mass is less than the sum of its constituent protons and neutrons, so where did the excess mass go when they were formed? If the iron ball is accelerated to near light speed, its mass seems to have increased, so where did this extra mass come from if it actually happens at all? If the mass is located in a far fast moving galaxy, has it changed? These properties are explained in terms of the electromagnetic nucleus model of Charles Lucas.
