“Gravity” is actually a mixture of electrostatics buoyancy and density.
It is just the atmosphere pushing downwards.
Phoebe from the TV series Friends was right when she said that she didn’t feel pulled to the ground by gravity but rather pushed down by the electromagnetic atmosphere. She obviously was right about evolution being simply a nice fairy tale story as well. This video mentions curvature, but no curvature has ever been seen or measured.
