A new approach to gravity
In the framework of the Standard Model, the three fundamental forces arise due to certain symmetries in their quantum fields. Each force has a unique symmetry pattern associated with it.
To develop a similar framework for gravity, the researchers introduce a new mathematical quantity called the spacetime dimension field. This entity has four symmetries that give rise to the gravitational field when applied to every point in spacetime.
In other words, gravity naturally emerges from the symmetries of the spacetime dimension field, just as we see with the other three forces in the Standard Model.
