... Empty Space is a normally perceived as being a vacuum void of energy but as special relativity tells us a vaccum is actually the lowest energy state possible. (a very different definition from "empty".) Even at this low energy state you still have some (even if its very small) energy that accumulat ...

... 5: 0.1 and 100 M⊙ . The minimum mass is set by the mass at which it is possible to have H fusion. For M < 0.1 M⊙ , the core is not hot enough for H fusion, and thus the object is not a star (it would be a super-Jupiter or “brown dwarf”). The physics of the upper mass limit is not known. We simply do ...

A light bending effect due to the sun’s gravitational field, should, as theoretically predicted by General Relativity, take place at the Gaussian sphere, 2R, yielding 1/2 of 1.75 arcsec, at the Gaussian sphere, 3R, yielding 1/3 of 1.75 arcsec. This should be noticeable for nR using modern technical ...
