Duda Jarek Posted August 11, 2020 Share Posted August 11, 2020 Most of them directly use GEM, like Gravity Probe B - please specify experiment and we can discuss it. This question is not only "alternative history", but also many e.g. in SETI hypothesize existence of other civilizations - it might be worth understanding if their physics would be based on GR, or maybe on adding corrections to GEM - which might asymptotically reach GR? Not having Einstein, which experiment could convince e.g. them that it is necessary to give up flat spacetime and introduce intrinsic curvature?
