Contribution
It demonstrates the existence of non-trivial, non-topological solutions in induced gravity models with scalar fields, termed 'Gravity Balls,' highlighting variable gravitational constants.
Findings
Existence of 'Gravity Balls' solutions in scalar-tensor gravity models
Effective gravitational constant differs inside and outside the soliton
Provides a new class of solutions with potential gravitational implications
Abstract
The existence of non trivial, non topological solutions in a class of induced, effective gravity models arising out of a non minimally coupled scalar field is established. We shall call such solutions ``Gravity Balls'' as the effective gravitational constant inside the soliton differs from its effective value outside.
