To know the truth absolutely! That's often deemed impossible. However, the notion is false. What is truth, is knowable. The book presented here illustrates how it is possible for a person to solve complex problems, such as to double a square, in area, and than to know in the end that the result is absolutely correct; and all this without one having any special knowledge in mathematics and geometry. Plato illustrated how this is done in his 'Meno Dialog' in the 'Republic.' Now extend the process further and build on the 'Meno' principle to prove the Pythagorean theorem. At first glance, this seems impossible. However, when one extends the 'Meno' principle, by understanding its expression, one can say with absolute certainty that the result is correct by simply looking at the process with which the answer is derived. Plasma in the physical universe is as challenging in perception as the spiritual domain in the human sphere. Both are invisible, except by their effects, but they are understandable and knowable. On the same basis it becomes possible to recognize the outcome of plasma physics operating in the universe. This is important in astrophysics, because of the huge consequences that follow, when we mess up in our thinking. With the Ice Age Challenge now before us, we face two imperatives. One is to understand the physical dynamics, and to create the physical infrastructures that enable human living to continue in an Ice Age climate. The second challenge, the greater challenge, is to raise up our humanity to such height as will impel us to get the job done. Some say that miracles are needed on both fronts. But what of it? Are we, as human beings, not the miracle makers on the Earth? In the real universe, the cosmic operations are anti-entropic in nature, and expanding and progressing. We, ourselves are evidence of this progression. Should this progression have ended? Neither is our Sun isolated from the progressive nature of the universe, but expresses its dynamics, its resonating plasma streams, and their reflection in the climate on Earth. Shouldn't we develop ourselves spiritually and culturally, likewise? Climate Change reflects the nature of the universe. It should also be reflected in us. The Earth itself is the creation of the Sun, with its atoms having been massively synthesized in high-energy times near the center of the galaxy. The synthesizing plasma fusion is presently at a low state, though it is currently enhanced for our Sun by electromagnetic 'Primer Fields' that focus interstellar plasma onto the Sun in a highly condensed manner. When the plasma-focusing system becomes inactive, below the required threshold conditions, the Sun reverts to a type of cosmic default level with 70% less energy being radiated, and higher rates of solar cosmic-ray flux being experienced. All of this is knowable. At the present rate of plasma diminishment being experienced, the solar activity phase-shift threshold to the next Ice Age period may be crossed in 30 years, or in the 2050s, most likely. With the primer-fields system gone inactive by then, the climate on Earth will get 40 times colder than the Little Ice Age in the 1600s had been. Ice core evidence promises that. Without the needed preparations for human living in such an environment, 99% of humanity would die of starvation, both by the cold, and by CO2 depletion that diminishes agriculture, as more CO2 becomes dissolved into the sea. With the 'Primer Fields' being critical for our very existence, the exploration of them is likewise critical. This is knowable, too.
