论文摘要
否。如在当前观察频率下通过稀疏的地球阵列侵入测量的增值超质量黑洞的观察性外观的所有理论预测对许多关于积聚流量和发射物理学的未经测试的假设敏感。没有办法将违反一般相对论（GR）的行为与相关的“胃物理”假设根本不存在的更有可能的情况区分开。通过更长的干涉基准（可能需要空间任务）达到分辨率，与天体物理学无关的理论预测变得可观察到的分辨率将成为可能的GR测试。
No. All theoretical predictions for the observational appearance of an accreting supermassive black hole, as measured interferometrically by a sparse Earth-sized array at current observation frequencies, are sensitive to many untested assumptions about accretion flow and emission physics. There is no way to distinguish a violation of general relativity (GR) from the much more likely scenario that the relevant "gastrophysical" assumptions simply do not hold. Tests of GR will become possible with longer interferometric baselines (likely requiring a space mission) that reach the resolution where astrophysics-independent predictions of the theory become observable.
