Astronomers think that early in its life, Iapetus must have been hit by another moon, sending huge volumes of ejecta into orbit. Some of this condensed into a new moon that escaped into space. However, the rest formed an unstable ring that gradually spiraled in towards the moon, eventually depositing the material in a narrow ridge around the equator. Cassini's next encounter with Iapetus will be in 2015 which should give astronomers another chance to study the strangest mountain range in the Solar System."
Researchers recently announced that observations of gravitational waves provide evidence of inflation, a dramatic theory of cosmic creation. But there are so many different versions of 'inflation' theory that it can 'predict' practically any observation, meaning that it doesn't really predict anything at all. String theory suffers from the same problem. As for multiverse theories, all those hypothetical universes out there are unobservable by definition so it's hard to imagine a better reason to think we may be running out of new things to discover than the fascination of physicists with these highly speculative ideas. According to Keith Simonton of the University of California, 'the core disciplines have accumulated not so much anomalies as mere loose ends that will be tidied up one way or another.'"
Representing the opposite viewpoint, Australian Homeopathic Association spokesman Greg Cope said he was disappointed at the narrow evidence relied on by the NHMRC in its report. 'What they have looked at is systematic trials for named conditions when that is not how homeopathy works,' he said. Homeopathy worked on the principle of improving a person's overall health and wellness, and research such as a seven-year study conducted in Switzerland was a better measure of its usefulness, he added. There are about 10,000 complementary medicine products sold in Australia but most consumers are unaware they are not evaluated by the domestic medicines safety watchdog before they are allowed on the market."
