The universe is made by the relationship between two forces which are also somewhat paradoxical to each other.
The relationship involves variations of interaction which are instrumental in producing matter and everything in the universe, including gravity and the black hole and dark matter effects etc.
The forces govern all the physical laws and their contexts such as expected in GR - which doesn't have an external context and is therefore not entirely true.
The forces determine how much matter will exist at anytime and all of its properties.
So we can expect to see different sized planets having different gravitational values without pretending that those differences are due to a different mass.
We don't have to hollow out, or make up gaseous theories about planets, like for instance Saturn, in order to convince ourselves that that will be the only way they can remain in orbit.
This idea goes against the theory of the direct relationship between mass and gravity, which isn't true anyway, because mass doesn't cause gravity, but the forces which make up matter do.
