Gravitational waves ... an era when the expansion rate of the universe is around the mass of the scalar field. It would stop beyond this point as particle production would be shut down at some ...

The weight of an object is the force on it due to the gravitational pull of gravity at that point ... gravitational field strength (\(g\)) of a planet is the weight per unit mass of an object ...
