Neogularity

The opposite state of singularity. A point at which the laws of physics work to the millimeter. The masses of objects are calculated nanometrically by the universe and things like curvature are clear and exact.

In a black hole, there's singularity on the center, a point where the laws of physics don't work anymore. So in a white hole, there's neogularity at the center.

It is also possible that the Neogularity would have and possitive curvature, unlike a black hole, in which the curvature sinks to the singularity, the curvature of neogularity would be protruding, causing objects to move away from it as if they were on a ramp.

In a hypothetical universe, where white holes are possible, it its also possible the Neogularity on the middle of them.
That would be the reason of why the objects tend to move away from the white hole
