In the near two years plus fifty that it took David Barclay to assemble the seventeen chapters of Unity, although he did write an introduction, he revised it when he finished the book. Here now, is the introduction to the theory of Unity: Ever since Newton formulated his gravitational theory we have accepted the simple contention that gravity increases to the center of the Earth and inversely decreases from the center of the Earth in a manner whereby the force of attraction decreases in proportion to the inverse square of the distance…Newton based his theory on some very fancy footwork, which necessitated the invention of calculus. And up to this point the apparent rational logic of his mathematical innovations are considered to be beyond question, as the numbers don’t lie. But despite the accuracy of the mathematical calculations the idealistic legitimacy of linear based geometry being capable of accurately describing the dimensional properties of our planet is extremely doubtful.
