If gravity is a force, it’s a very weak one. But it don’t need to be strong for the emptiness of space. The distance of this weak effect is impressive, and is what gives it it’s great effect. But that’s because of the nothingness of space, and a neutral EM, not the strength of the force. The strongest, the EM is canceled. And there is zero motion impedance in or from space. Impedance to motion comes from matter inertia, not space.
If the EM of the cosmos was lined up, gravity would cease to exist. It’s effect would be way too weak.
And there would not be any slow velocities. This cosmos wouldn’t be this cosmos with aligned or net EM. Gravity keeps cosmos matter velocities very slow.
If we knew what true inertia was, maybe we could understand how they line up in the manner they do.
I believe inertia is two accelerations. A stationary rolling acceleration, producing a secondary rotational acceleration. Producing quantum secondaries on top the stationary c roll. And introducing handedness to the cosmos.
We’ll have to really mine deep to understand inertia and gravity.
