If general relativity based models have struggled to help predict or explain planetary system formation and exoplanet observations, I think we should have the same level of expectation about how helpful a general relativity based black hole model will be.
- dotnet00 4y agoYou might as well be saying that if fluid dynamics models have struggled to help predict or explain CPU performance increases, we should have the same level of expectation about how helpful a fluid dynamics based model of aerodynamics will be, i.e. complete nonsense
- JacobThreeThree 4y agoPlanet formation is a subset of system formation which is a subset of galaxy formation and all are within the same observational astrophysics domain. CPU performance and aerodynamics are two completely unrelated domains.
- DiogenesKynikos 4y agoGeneral Relativity has pretty much nothing to do with planet formation. Newtonian gravity is good enough for that problem, and the problems have nothing to do with not understanding gravity well enough. The problems have to do with things like complex chemistry in stellar accretion disks, how grains in these disks stick to one another to eventually form rocks, and so on.
- JacobThreeThree 4y agoWhether the problems with the models are with general relativity, Newtonian gravity or other issues, the point is that the models have problems.
- DiogenesKynikos 4y agoWhich models are you talking about? The fact that some models somewhere have problems has no bearing on whether the image reconstruction for Sgr A* is valid.
