Einstein’s Explanation of the Unexplainable
Mass is both a property of a physical body and a measure of its resistance to acceleration (a change in its state of motion) when a net force is applied.
The Higgs boson, discovered at the CERN particle physics laboratory near Geneva, Switzerland, in 2012, is according to the Standard Model of particle physics what gives all other fundamental particles mass. However, despite the work of thousands of researchers around the world, nobody has been able to figure out exactly how it does that or why some particles are more massive than others.
However, there is another way to understand mass and its resistance to acceleration based solely on the field concepts of Einstein’s theories.
For example, Einstein defined the physicality of mass in terms of the energy density associated with a displacement in space-time which he quantified by the equation E=mc^2. This means he also defined the reason some particles are heavier than others is because they have a greater displacement and therefore a greater energy content than other masses. Pitting it another way the equation E=mc^2 not only defines physicality of mass but also quantifies why some particles are heavier that others in terms of in terms of the field properties of space-time
However, his equations and the observations of particles in particle accelerators have confirmed the relativistic mass of a body increases over its finite rest mass as it is accelerated with respect to an observer and that energy must must be added to it to do so. Additionally, Einstein also tells us the rate at which energy can added to a mass is limited by the speed of light. This means according to relativity, the reason why mass resists acceleration is because the speed at which energy can be added to it is limited by the speed of light. Putting it another way according to it, the reason mass resists acceleration MAY not be related to the field properties of a Higgs boson but to a physical property of space-time that limits the rate at which energy can be added to it.
In other words, one does not need the Higgs boson to explain a particles mass and why it resists a change in motion because one can use the OBSERVABLE properties of our environment and of Einstein’s theories to do so.
