In present Physics there is no definition of "mass". A mass is a quantity of matter. In present Physics, there is NO unit of measure for a quantity of matter. A gram (which is a unit of weight and pressure) is the wrong unit of measure of mass. Indeed, because non-particulate matter (called "dark matter") has no weight, there is no way to measure a quantity of it other than by the fact that a quantity of it in a given zone changes the local density gradient (called a "gravitational field") enough to change the weight (reaction of particulate matter embedded therein) by a measurable amount.

For a given mass, which is invariable regardless of a change in its weight, and a given energy, which is a function of its speed relative to a given target with a given mass but a variable weight, all three are independent variables. (The quantity of each is variable until it is put into the equation. Once stipulated there, neither that quantity of matter or of pressure or of the speed of light is variable, so they are invariable once an amount is stipulated.
<< If we look at the velocity of light, C, it is obvious that it must be one of the independent variables. Since velocity involves only length and time, we can measure the velocity of light under conditions that are independent of either mass or energy. >>
"Energy" (the ability to do work. i.e to change the state of motion of a given mass) is a pressure; measured in grams. If no particulate mass is present in a given space, thus no locatable referent is present, the speed of light cannot be measured. Accordingly, the velocity of light doesn't exist in the absence of a massive object.
<<Similarly, it is obvious that energy, E, is an independent variable since energy involves only force and length, we can also measure it under conditions that are independent of the velocity of light and of mass. >>
Since energy (a net pressure) is a function of v, and v (dx/dt) requires a referent for x = 0 (as does c) there is no way to measure the value of E (a "force" is a net pressure, measured - in grams - independently of the area of its application); there is no way to measure it independently of the mass of its target object.
<<There remains only mass to be examined. >>
Good idea. Why not start by defining "mass" (a quantity of matter, whether or not it has any weight) independently of "force". And then define "force" (a quantity of net pressure) independently of mass.
<< ... Seen in this light, what we consider to be mass [IN GRAMS!!} is actually a property which is an indication of the energy required to change the velocity of the quantity of energy defined by E=M*C^2.>>
You got that inside out and backward, Hoax! The weight is a property of particulate matter and the quantity of energy is the amount of force (the textbooks all agree that "weight is a force") required to change the velocity of a given mass (in "densa", not grams). Once that is understood - which may take awhile - the meaning of e = mc^2 (which says that the quantity of energy - a net pressure - is equal to the weight of a quantity of particulate matter times the speed of light squared) will be too. It will then be obvious that matter and energy are NOT interconvertable, as now thought; and that- as stipulated by the first Law of Physics - neither of them can be created or destroyed. Once THAT is understood it will be obvious that the Bif Bang (which says that all the matter and energy in the entire universe originated at a point in nowhere, at a time that didn't yet exist, is as stupid as most of the present theories of Modern Physics.

"The Nature of Mass"
(See also our sister website reticsessays.com)
We have all been taught in our physics classes that mass is one of the fundamental entities of our reality and that all of the effects occurring in our Universe are dependent on interactions between masses. It behooves us then to examine what we know of mass.
About 40 years ago the writer came across the observation in a Scientific American article that, in the equation E=M*C^2 there can only be two independent variables. One of those variables, E, M, or C must be dependent upon the other two. If we look at the velocity of light, C, it is obvious that it must be one of the independent variables. Since velocity involves only length and time, we can measure the velocity of light under conditions that are independent of either mass or energy. Similarly, it is obvious that energy, E, is an independent variable since energy involves only force and length, we can also measure it under conditions that are independent of the velocity of light and of mass. There remains only mass to be examined.
If one wished to determine the mass of an object, one could weigh it (gravitational mass), shake it (inertial mass) or observe the amount of energy released if it where annihilated. Weighing a mass provides a measurement of its mass but the observation is made in terms of a reference mass (e.g.- the mass of the Earth) and, in effect, we would then be defining the mass in terms of another mass. This is hardly an acceptable solution since it leads to a dead end. Annihilating the mass is a legitimate solution providing one can measure the energy content of the end products without relying on a measurement of their mass (such a reliance would be a form of circular reasoning). The remaining possibility is to measure the inertial properties of the mass by, for example, shaking it and measuring the force required to produce an a given acceleration. This type of measurement involves force, length, and time, all of which are directly observable and does not suffer form the limitations of the other methods. What we would then be doing is measuring mass as the incremental impulse required to produce an incremental change in velocity. (In the case of photons and neutrinos it might be desirable to remove the word "incremental" from the measurement since these particles exist only at the velocity of light). Seen in this light, what we consider to be mass is actually a property which is an indication of the energy required to change the velocity of the quantity of energy defined by E=M*C^2. With this definition, the Lorentz Transformation for Mass becomes equal to the cube of the accepted value and allows problems involving STR to be solved without resorting to momentum. This conclusion is consistent with STR because the conventional Lorentz Transformation results when one integrates this transformation between the velocity limits of 0 and V.
An intellectual difficulty occurs when one considers the so-called "massless" particles. They have this name because they have no "rest mass". A reasonable man would consider such a terminology to be frivolous because these particles exist only when traveling at the velocity of light. They have no "rest mass" because they don't exist at rest. These so called "massless" particles do however, possess inertial mass as evidenced by the radiation pressure they exert when their velocity vectors are altered, either by reflection or absorption. They provide the same reaction force as would a material particle of the same relativistic mass that was traveling infinitesimally close to the velocity of light. They also experience gravitational forces that are twice the force that would be experienced by a material particle of the same energy. A simple "thought experiment" as outlined in Part 4 of http://einsteinhoax.com/gravity.htm easily shows this. (The writer has received a rather cryptic E-mail from someone who apparently is associated with the physics establishment to the effect that the photon imparts momentum because its energy is equal to the product of its frequency and Plank's Constant and it is traveling at the velocity of light. The sender denied vehemently that the expression E=M*C^2 and the idea that even though the photon contains energy and imparts a momentum equivalent to a mass of that energy traveling at the velocity of light, means that the photon has mass. Bertrand Russell is reported to have said that the sign of a great mind is the ability to hold two mutually exclusive beliefs at the same time. The writer disagrees with him. That ability is the sign of a mind which is too lazy to resolve the contradiction and/or is too damn lazy or too damn stupid to resolve it)
The inertial and gravitational masses of the so-called "massless" particles have a significant effect on our understanding of cosmology. A back of the envelope calculation suggests that the inertial mass of these particles, as evidenced by the 3 degree Kelvin radiation temperature of space, exceeds the inertial mass of the matter in our Universe by a factor of 10. When we consider that neutrinos are formed in nucleons that have 1800 times the energy content of the source of photons (electrons), it may be possible that the mass of neutrinos outweighs the mass of photons by a factor of 1800! Looked at it in this light, our Universe may actually be a gasbag of photons and neutrinos filled with a miniscule amount of the dust we call matter. Rather than being the King of the Universe, what we call as matter may actually be only a miniscule contaminant.
If we examine the radiation pressure produced by the observed level of photons in space, it is easy to see why space appears to be expanding. Radiation pressure is counteracting the gravitational pressure. It is also easy to understand why the dynamics of galaxies appears to be skewed by what is termed "dark matter". There would seem to be no need to postulate the existence of "dark matter" until the gravitational and inertial effects of the photons and neutrinos that populate the Universe have been amply explored. This has not been done, primarily because these particles have been foolishly defined as "massless".
