APPARENT ULTRA-RELATIVISTIC ENERGY DENSITY INFLATION OF ASTROPHYSICAL BODIES INTO APPARENT BLACK STARS

In this note, an interesting result of relativistic effects between inertial reference frames is offered as a gedanken experiment: to observers in one inertial frame, objects in another inertial frame approaching or receding differentially close to the speed of light, relative to the observers’ inertial frame, will appear to experience both significant mass inflation and length contraction, resulting in greatly inflated observed energy densities. This note determines, from the point of view of the observers, the respective Lorentz factors above which an arbitrary spherical object will appear to attain a black star density and an apparent Planck density.
