Energy is viewed within the current paradigm as an inherently limited property of the universe. Its motions and economy are assumed to be governed by self-limiting functions, while the anomalies are left unexplored. However, it is in these anomalies we are finding exceptions to the heretofore 'established' laws of physics.
Science has evolved from experimental beginnings, and in order to reconcile the findings of early scientists, a common theory was adopted. This is most particularly centered around the 2nd Law of Thermodynamics which, as currently applied, pre-supposes the Universe to suffer from a condition known as 'entropy'. It surmises, despite much contradictory evidence, that energy can never appear at any one point in space without being drawn out of another. The theory rules out the existence of a 'perpetual motion' machine that could power itself without depleting its source of power.
The 2nd Law's Primary tenet, simply stated:
"All energy is converted from one form to another, never created or destroyed."
The gross assumption implicit in the 2nd Law rests on the premise that the Universe, as a whole, is an "isolated system" into which no (as yet unmanifest) energy can flow. This is indeed an assumption based upon purely metaphysical constructs. If empiricism is the guiding philosophy of science, how can such an unfounded assumption be so religiously adopted by the so-called rationalists who champion it?
It appears most of these conclusions are based on a consensus reality that mirrors the past 200-years of early industrial development. As all inventions to-date have been largely inefficient and consumptive, there is no precedent in science for the advent of 'New Energy' -- pollutionless, totally renewable, free energy from space. Numerous examples of such technology now exist that cannot be reconciled with the prevailing theoretical constructs.
All that awaits is a scientific renaissance that can transcend 'the known' and admit another paradigm.
