There is no such thing as Dark Matter, Dark Energy or Black Holes.

The assumption that the Physical Constants do not vary and remain fixed on all scales for mass, charge, wavelength and frequency is the 300 year old error that leads to the conclusion that the Universe consists of 23% Dark Matter and 72% Dark Energy. The idea that the Constants actually vary and are dependent on the scales of the component parameters results in solutions to the equations describing the dynamics of Galaxies which clearly demonstrates that the observable Universe corresponds with the actual amount of visible matter that is detected as quarks and leptons so that Dark Matter and Dark Energy actually do not exist. Newton's Gravitiational Constant G approaches the accepted current experimental value of 6.67428 x 10^-11 only for the case of relatively large masses, large wavelengths and small frequencies and when these parameters are taken as the converse according to scale, then the variation in G becomes evident in the range of experimentally acceptable significant figures. The realization that G is a variable also leads to the fact that there are no such things as Black Holes, and that Gravity is Electromagnetic.
