Fredkin's "Five Big Questions With Pretty Simple Answers"
Accordin to Fredkin, "Digital mechanics predicts that for every continuous symmetry of physics there will be some microscopic process that violates that symmetry." Therefore, according to Fredkin, at the Planck scale, ordinary matter could have spin angular momentum that violates the equivalence principle.There might be weird Fredkin forces that cause a torsion in spacetime. The Einstein-Cartan theory extends general relativity theory to deal with spin-orbit coupling when matter with spin is present. According to conventional wisdom in physics, torsion is nonpropagating, which means that torsion will appear within a massive body and nowhere else. According to Fredkin, torsion could appear outside and around massive bodies, because alternate universes have anomalous inertial effects.

“Science asks no questions about the ontological pedigree or a priori character of a theory, but is content to judge it by its performance; and it is thus that a knowledge of nature, having all the certainty which the senses are competent to inspire, has been attained—a knowledge which maintains a strict neutrality toward all philosophical systems and concerns itself not with the genesis or a priori grounds of ideas.”
—Chauncey Wright (1830–1875)
“On the whole our armed services have been doing pretty well in the way of keeping us defended, but I hope our State Department will remember that it is really the department of achieving peace ...”
