so what does "E=MC^2" imply? To me "E" is the quanta that represents Energy. "M" represents the quanta of Mass which so happens to be found to occupy a maximum area equal to C^2.. Therefore obviously the more mass we compress into C^2 the more Potential energy we could state we have stored in C^2, we should also note the more solid this area would present the more mass therein, and the question now is where does kinetic energy come into the equation... "Energy" we may or may not know represents the ability to do work and or better inferred to cause change and when we have a stored amount of energy the energy can be inferred as Potential Energy, a single mass occupying a C^2 area can be said to be with a potential of a single mass and if we introduced another mass to the C^2 area we could imply we now have the potential of two masses and or the energy of two, but how can we utilise this energy? we are already somewhat doing this via the use of common Air compressors.. Lets briefly turn our attention to change or the inference to kinetics and or Kinetic energy where stored and or Potential energy is converted to Kinetic energy energy exerting change and or some sort of momentum (velocities).. Change can be expressed best via a fraction of a velocity at "c", keep this in mind because when we have two or more velocities at "c" meeting we have an area that is more dense or we could see this as an area experiencing opposing forces (or think of two or more breezes meeting in a set area), better expressed as a Space-Time area via the calculus of implied area experiencing velocities for a given time frame and or rate and it should be noted the central meeting point presents as an area with simply a fraction of implied meeting velocities even though the velocity remain constant relative to all other local velocities and this is the same as with in all space-time areas.. Momentum and or a velocity is the result of change, and momentum can only be possible via force and it should be noted force is the result of velocities and can only ever be repulsive, no ifs and no buts! OK having established that an area with some density the minimum being near vacuum is an area equal to C^2 and is what a single mass can occupy (as anything greater in area its potential would equal closer to zero) and therefore it should be considered with the least potential and or presence as we refer to it as (space) hence the maximum velocity at "c" being of course with least opposing potential. We can now imagine to introduce enough mass so that an area of C^2 is with somewhat more density to it, we should note this can be done via introducing velocities from new origins and or via two or more established space-time areas with implied velocities can be compressed together, Importantly the area should be seen with a lot more Potential energy to it by us doing this, this also implies the compressed area must be experiencing an ongoing opposing exertion if it is to exist in an ongoing manner, and that's where the ongoing velocities come into it, as other wise the compressed mass would spread out back to occupy its maximum occupancy again... And here is where many do not understand that all areas that present as solids must be experiencing an ongoing exertion to it as in (gravity) but note here and now gravity is not a magical pulling force but rather the result from the inbound force/s and or velocities that created the local space-time and or solid area in the first place, and no where more is this confusion apparent than when we have before us a solid mass surrounded by highly kinetic mass that is in a near vacuum state, this may seem at first a contradiction and if one does a search on gravity and relativity images - Not one of the images have depicted the relativity grids correctly because of this misunderstanding.. Every single image I have come across have the compression grids exerting space-time incorrectly and if one was to animate them would have the implied solid area exerted away from implied meeting velocities ending up in the solid area able to become kinetic from the lacking inbound velocities~ allowing it to spread out and resume to occupy its maximum area again.. Any questions?
