>>11087400The 3D shape is a surface of constant proper time along the 4D shape. Everything in the universe is 4D, this is known and has been taught in the undergrad physics curriculum for many decades. Furthermore, there is no general relativity in less than four dimensions, and we have ABSOLUTELY NO DATA about happens between a given surface of constant proper time and what we can see on the past light cone. You might as well write "here be monsters" between the past light cone and the hypersurface of the present because we have no idea what goes on there. I agree that dark matter is a better guess for the anomalous rotation, but the data has convinced me that there is no dark matter, and the only theories of dark matter which haven't already been ruled out by what we can see on the past light cone are completely fucking retarded and contrived, and when you compared those "dark matter" theories which are no yet ruled out to my "dark geometry" suggestion, my opinion is that dark geometry is a lot more reasaonable and more consistent with what is usually called "physical." I mean... "the dark matter chameleon field?" Are you fucking kidding me?
>then it must be because of lensing That's completely not true, there's a million things it could be. It's even more not true because lensing is a classical optical effect and you can change it. All you can do with lensing is to calculate the Sachs-Wolfe effect and the integrated Sachs-Wolfe effect.
Your suggestion "it can only be lensing" ignores the obvious truth: it can be any of an infinite number of things that no one thought of yet and whose fundamental principles are not yet fully understood. It's like saying, "My keys have to be around here somewhere!!!" The truth is, a burglar might have taken your keys while you were posting on 4chan.
