Crackpots and Geniuses seem to be equally excluded from mainstream science. It presents a dilemma when it comes to including numerous alternative or fringe science sites and concepts. Mainstream science has become frustratingly dogmatic. The more we insist we know all there is to know, the more difficult it becomes to discover. We should not confuse science with truth. A theory, even if it makes successful predictions, is still a theory. The success of those predictions doesn’t prove the theory is truth, it only proves that it makes accurate predictions in a set of circumstances.
Newtons law of gravity made wonderfully accurate predictions under most ordinary circumstances. Nature being what it is provided us with one example where Newtons law of gravity failed, in the motion of Mercury. For the motion of Mercury to be fully explained, relativity had to be invoked. General relativity makes accurate predictions under a broader set of circumstances than does Newtonian physics. But it fails under some circumstances also. It fails to properly describe the rate of deceleration of the Pioneer spacecraft. This has become known as the Pioneer Anomaly. The anomaly hasn’t been limited to Pioneer, other spacecraft near the edge of the solar system have demonstrated similar anomalous deceleration.
It is clear to me that we don’t understand the force of gravity to the degree we think we do. Gravity waves have been predicted by physicists for decades. Numerous gravity wave experiments, Australia has ACIGA, The German-British project GEO 600, NASA LISA spaced base interferometry experiment, LIGO at CalTech, the Japanese projects LIGM and Tama 300, the French/Italian project VIRGO and the Italian project AURIGA, have all failed to definitively detect gravity waves.
A weak but existent connection between gravity and electromagnetism was predicted by Einstein. An effect still very weak but orders of magnitude stronger than predicted. Such a force has been measured around rotating superconductive rings. Gravitational forces emanating from rotating superconductors have been measured at various laboratories. They have fallen far short of those claimed by Eugene Podkletnov, a Russian scientists, who claims to have seen gravity reduction up to 2%, but still several orders of magnitude greater than predicted by Einstein.
These things and more convince me that there is still much to learn, and so I have included some sites which I am confident contain crackpot material because I believe within them from time to time also will be found some genuine science that will not make it’s way into mainstream journals anytime soon.
