Understand

We consider general relativistic homogeneous gravitational collapses for dust and radiation.

We show that replacing the density profile with an effective density justified by some quantum gravity framework leads to the avoidance of the final singularity.
The effective density acts on the collapsing cloud by introducing an isotropic pressure, which is negligible at the beginning of the collapse and becomes negative and dominant in the strong field regime.
Event horizons never form and therefore the outcome of the collapse is not a black hole, in the sense that there are no regions causally disconnected from future null infinity.
