One way to view things is that GR was obvious to a smart person with good enough tools and that if Einstein wouldn't have discovered it someone else would have soon after.
- mr_mitm 4y agoHmmm, when I studied GR, the consensus was that it came out of nowhere and if it wasn't for Einstein's genius, it would have taken at least a long time until someone else had discovered it. But you make a good point. Ultimately it's an unanswerable question, I guess.

- kryptiskt 4y agoOf all the physical theories, general relativity is probably the one that's least likely to be true of. Because it just wasn't needed in all its generality at that point of time. Instead of going from first principles like Einstein some other physicist could have developed it from the other end, and made corrections to Newton mechanics based on the observed precession of Mercury and the deflection of starlight by the Sun (if someone would have done that observation without the impetus of GR). It could have been akin to how quantum theory in its first 25 years was a collection of ad-hoc explanations of various phenomena using the quantized energy idea but having no generalized theory of them.
- zmgsabst 4y agoQuantum mechanics and relativity are both explanations of the interferometer from Michelson-Morley. Which turns out to work, now called LIGO, if you apply relativistic and quantum corrections.
- jacquesm 4y agoWe'd have found out for sure when we first built a GPS system without relativity correction. It wouldn't work and that experimental error would have to be explained somehow and that in turn would lead to the discovery of GR if it had not been discovered through some other means at that time.
- mannykannot 4y agoDavid Hilbert, for one, was apparently close. That said, I feel that it is a bit of a stretch to call it obvious (maybe more obvious in the sense of "this is the way to go" rather than that the answer was obvious.)
- mr_mitm 4y agoFrom what I remember, Hilbert actually got the equations first by applying the principle of least action, so a much more mathematical than Einstein's physical approach. However, everybody agreed that Einstein did all the heavy lifting (he worked closely with mathematicians for years to figure things out), so that's why they aren't called the Einstein-Hilbert equations.
