"Opposite side" of GR
I am trying to consider kind of "opposite side" of GR.
Let's consider some area in space where density of matter is less then average density of matter across the universe and in every direction average density of matter can be viewed as being higher than at this particular place.
Then gravity in this area would be repulsive, right? Light will bend away from that area and matter will "fall out" of this place.
Is it possible to find some description of that place similar to GR description for gravitating body. Let's say we make necessary assumptions about symmetry of this situation.
Something like smoothing out of topology as you approach center contrary to bending?
