No, no no no... That's not how it works... The earth is flat period, there's no debate to have about that, it's just that we live in a curved universe that's all. The curvature of space-time makes you see the earth as round, but it's an optical illusion, in fact it's flat https://www.nature.com/articles/s41550-019-0906-9 >>The recent Planck Legacy 2018 release has confirmed the presence of an enhanced lensing amplitude in cosmic microwave background power spectra compared with that predicted in the standard Λ cold dark matter model, where Λ is the cosmological constant. A closed Universe can provide a physical explanation for this effect, with the Planck cosmic microwave background spectra now preferring **a positive curvature at more than the 99% confidence level**. Here, we further investigate the evidence for a closed Universe from Planck, showing that positive curvature naturally explains the anomalous lensing amplitude
