I thought Einstein’s General Theory of Relativity proposed that gravity isn’t a force but a distortion of space-time caused by the mass of an object that resides in space-time.
The geometry of space due to gravity still results in an acceleration of mass. You can still use the formula for convenience: F = mg, where the force is F, the mass is m, and the acceleration g is gravity.
But let's not loose sight of the big picture. The universe is expanding at an increasing velocity. That means some force is accelerating it.
