Einstein's Theory Improved?
skaet writes to tell us that A Chinese astronomer from the University of St Andrews claims to have fine-tuned Einstein's theory of gravity. Dr Hong Sheng Zhao has created a 'simple' theory which could "solve a dark mystery that has baffled astrophysicists for three-quarters of a century." This new law seeks to discover whether Einstein's theory was correct and if dark matter actually exists.
Newton and Einstein's theories of gravity don't always work, so cosmologists decided to make up some new and coincidentally undetectable stuff -- Dark Matter and Dark Energy -- to help them out. The more I read about these ideas, the more they look like fantasy as opposed to science. It's almost as bad as String theory! Why don't the theorists stick to explaining what can actually be observed and measured, instead of making up stuff in order to prop up theories that have more likely found their limits. I can just feel which way Occam's Razor is eventually going to cut on this one. Besides, all my life I've been hearing that gravity is the least understood of the four fundamental forces of nature, so perhaps it's about time it got a tune-up.
