- Title
Is the current estimation of the ratio of dark matter to visible matter the result of a simple miscalculation?
- Authors

- Abstract
The gist of this essay is that the amount of dark matter needed to explain the rotation curves of stars in galaxies is grossly overestimated and that the source of this overestimation can be attributed to a set of classical calculation errors that have resulted in an underestimation of the magnitude of the gravitational force acting between objects. Because Einstein based his calculation upon the correspondence principle--upon the assumption that the predictions of general relativity should correlate to the predictions of classical gravitational theory in the weak-field, low-velocity, nonrotating limit--this classical error was incorporated into the general theory of relativity. The reformulation of Newton's law of gravity produced theoretical values for the orbital speeds of stars in galaxies that are in good agreement with observed values.
