Einstein’s Mass-Energy Equivalence and the Indistinguishability of Matter

The premise of the question is flawed. Energy does have units. Energy is measured in Joules. 1 Joule is a Newton-meter. 1 Newton 1 kg-m/s2. Therefore, 1 Joule 1 kg-m2/s2. According to Einstein’s famous equation, Energy mass x the speed of light squared, or E m x c2. In units using kg for mass and m/s for speed, E kg-m/s2 or E kg-m2/s2 or Joules.

Mass and Energy: Not Different Forms, but Forms of the Same Fundamental Quantity

Mass and energy are not different. In fact, they are physical measurements of the same fundamental quantity, MATTER. In many scientific circles, especially in advanced physics courses, mass is not measured in kilograms (kg) but in units of energy (Joules) and even more frequently in units of “baby Joules”, specifically electronvolts (eV). The rest energy of subatomic particles, such as electrons, protons, and neutrons, is often given in kilograms in textbooks but in research, it is more commonly given in eV, MeV, or GeV.

For instance, the rest mass of an electron is given as 9.1 x 10-31 kg. In research, this is simply 0.5 MeV. In the realms of research, distances are measured in nanoseconds. This is because the speed of light, c, is exactly 1 foot per nanosecond! Light travels one foot in a nanosecond. Therefore, distance and time are simply dimensions of our Universe.

The parallel idea to this is that both mass and energy are forms of matter in our Universe. Most researchers accept Einstein’s equivalence of mass and energy, E m c2, as a given. This equation simply acts as a reminder that mass and energy are two forms of the same thing: matter.

Mass as an Undefined Property and the Legacy of Relativity Theory

Certainly, mass is an undefined property in physics. Because of this lack of knowledge about what mass is, theorists are relatively free to mold the property of mass into something that their theory needs for bolstering. In Relativity Theory, the emphasis is on energy being the substance from which everything is formed. Mass is the primary property, and energy is defined in terms that include mass. Since mass is undefined, it is relatively easy for Relativity theory to boost energy above mass in terms of property importance.

That which is unknown, i.e., mass, can be declared to be subordinate to energy without much opposition. Thus, mass, the most important property in the universe, except for the speed of light, becomes just one of the forms of energy. This is not empirically supportable. The lack of direct empirical support has become less of a concern for theoretical physicists. Theories now are free to offer imaginative solutions, needing only indirect empirical support. This is the legacy of Relativity Theory. Relativity Theory itself lacks empirical support for its fundamental claims, and there is no empirical evidence supporting the claims that either time or space suffer effects caused by objects or cause effects upon objects.

Conclusion

The concept of mass and energy being indistinguishable is deeply rooted in theoretical physics, particularly in Relativity Theory. While the equivalence E m c2 provides an elegant framework, the nature of mass itself remains an enigma. The willingness of physicists to interpret mass in various ways underscores the complex and evolving nature of our understanding of matter and energy.
