An article in New Scientist (10/24/15) heralds the end of physics as we know it. What’s at stake here is Einstein’s theory of General Relativity. The article is entitled “Could cosmic megastructures be intruders from another world?” and is an attempt to get around the problem that General Relativity is defunct by arguing that all these megastructures that shouldn’t be there according to General Relativity, are not actually in this universe at all, but in fact are “illusory” and are windows into “other dimensions” or into “parallel universes.”
Einstein’s theory of General Relativity is a complex mathematical theory about the curvature of space-time. He adapted the Riemann curvature equations which were intended to measure the curvature of objects in 2-D and 3-D spaces and simply plugged a fourth dimension of time into these equations. The answers that emerge from these equations cannot actually be envisaged by us in our 3-D world view and Einstein himself was the first to admit that these calculations have no “physical” significance.
