The mass vector is a vector quantity that describes the magnitude and direction in which the mass acts for any point mass in the known universe in its movement about the universe's central axis of rotation. The discovery of the mass vector is commonly attributed to Sir Isaac Newton and is documented in a recently recovered chapter of his treatise De motu corporum in gyrum. The mass vector is defined as the resultant vector of the division of the force vector by the acceleration vector (or the derivative with respect to position of the dot product of momentum and time, which is referred to as the Hang and abbreviated Ξ). Very little is yet understood about the properties of mass vectors because they are hypothesized to exist only within the singularity of black holes where the extreme gravitational force compresses acceleration to a scalar quantity. There is some controversy regarding the definition of the mass vector, as seen in James Clerk Maxwell's treatise Matter and Motion. Maxwell defines the mass vector as follows: "... a mass-vector [is]... the operation of carrying a given mass from the origin to the given point. The direction of the mass-vector is the same as that of the vector of the mass, but its magnitude is the product of the mass into the vector of the mass. Thus, if OA is the vector of the mass A, the mass-vector is OA*A." However, this definition does not take modern quantum theory into account, and is commonly considered to be obsolete.
Mass Vector Criticisms
Although many physicists agree on the details of mass vectors, there are still some debates. Many critics believe that mass vectors are in direct contrast to Galileo's classic idea of Falling Bodies. They believe that mass vectors travel through a special media, similar to that of light traveling through Aether. It is impossible to prove this in all circumstances, so it is merely a theory. The critics still remain adamant about the disbelief of mass vectors as quantities which are normally affected by the physical world.
