Here's an arrogant reply I received regarding this article: Experiment that is almost certainly wrong, or large galaxies would be sucking their local small cluster galaxies in at rates that astronomers would have seen a long time ago.
First: the article is wrong. The magnetic analogue of the gravitational field is not a prediction of general relativity. It is a consequence of the Lorentz invariance of physics, and was predicted by Heaviside in 1892, 14 years before the special theory of relativity, and 24 years before the general theory of relativity, using an analogy with Maxwell's equations (which were already Lorentz invariant) but no one [then] knew why. Second: If the effect was genuinely a manifestation of a magnetic analogue of gravity (which does indeed exist) if it existed at the strength quoted, an enormous laboratory [called "the universe" -- you may have heard of it] would be able to duplicate the results in stars, galaxies, and clusters. It doesn't. That's why there has been no follow up to this blunderously awesome "experiment" in eight years, On Thu, Feb 20, 2014 at 1:51 PM, John Berry <berry.joh...@gmail.com> wrote: > > http://news.softpedia.com/news/The-First-Test-That-Proves-General-Theory-of-Relativity-Wrong-20259.shtml > > According to Einstein's theory of general relativity, a moving mass should > create another field, called gravitomagnetic field, besides its static > gravitational field.
