The calculational problems arising from the, testable, zero-dimensional "Point-particle" approximation has given rise to the one-dimensional "String" approximation. Decades of untestable, speculative, theory based upon closed and open microscopic strings, necessitating more and more exotic geometric extensions to the observable universe, viz: Extra dimensions (most of which are "Rolled-up" and so invisible), Branes (n-dimensional membranes), diffusion through stacks of which cause the attenuation of gravitational force, Multi-universes, (The "Multiverse") allowing the probabilistic bifurcation of physical effect etc, etc. Thousands of "Physicists" are working in this "Alice-in-wonderland writ large". Is it physics, metaphysics or philosophy? How is this catastrophic state to be resolved? Jim Baggot has, at last, exposed the truth behind the "Search for truth".
