GreenTracker| The results of two new and independent studies confirm that Einstein’s General Theory of Relativity is remains the gold standard in physics, fighting off a potential upstart known as “f(R) gravity.” Alternative theories to Einstein’s are relevant as explanations for the accelerated expansion of the universe.
These studies, made using NASA’s Chandra X-ray Observatory, compared mass estimates of 49 galaxy clusters and found no evidence that gravity is different from General Relativity on scales larger than 130 milliion light years.
We don’t imagine that many of our readers care about this data, except to reinforces the vastness of the infinte number of universes beyond our own. Planet Earth is just a speck in this massive configuration of molecules in the osmos. And we manage to reduce this mind-boggling vastness to the next episode of ‘Sex and the City’ or ‘Gossip Girls’. It’s rather amazing, when you think about it. Anne
