Posted by urnlfn on December 18, 2022, 2:15 pm, in reply to "No. But GR cannot be replaced by a theory that FAILS to account for curvature of space," GR makes predictions based on curved model spacetime, but that does not mean curved spacetime is real. The same predictions can be achieved by other mechanisms.

I can't." Easily, except that curvature is in FOUR dimensions. - DFM November 23, 2022, 6:52 am I don't have the background to make an argument sufficiently technical to pass peer review - urnlfn November 23, 2022, 2:23 pm Simple Proof Space Is Curved. - DFM November 28, 2022, 6:56 am The fact that we understand that light is following a curve implies that there is a straighter line - urnlfn November 28, 2022, 5:29 pm OK. DEFINE a straight line in REAL space-time. I dare you. - DFM December 3, 2022, 4:28 pm A straight line connects the centers of mass of two massive bodies - urnlfn December 3, 2022, 5:13 pm MANY POSSIBLE lines connect the centers of mass of two massive bodies. - DFM December 4, 2022, 6:15 am Only if you assume that space is malleable. i don't believe it is. - urnlfn December 9, 2022, 9:20 pm You can define neither curvature, not the character of a straight line. - DFM December 10, 2022, 3:31 pm Incomprehensible mathematical gobbledygook. - urnlfn December 10, 2022, 3:46 pm Comprehensible mathematical geometry. - DFM December 12, 2022, 8:20 pm I don't believe GR is the end of the story - urnlfn December 13, 2022, 3:22 pm On a Macroscopic scale, GR has passed every experimental test with flying colors. - DFM December 15, 2022, 6:12 am GR nevertheless has limited utility and is therefore not the ultimate theory - urnlfn December 15, 2022, 11:02 am In Science, There NO ultimate theory. - DFM December 16, 2022, 5:35 am Correct - urnlfn December 16, 2022, 10:04 am No. But GR cannot be replaced by a theory that FAILS to account for curvature of space, - DFM December 18, 2022, 10:14 am Reification fallacy - the map is not the territory - urnlfn December 18, 2022, 2:15 pm "The same predictions can be achieved by other mechanisms." - DFM December 19, 2022, 8:17 pm Not true.
