In "his" all powerful outflow from within "his" literal, "hole,"( read well), would be the "imput" of "his" end. A continuation of all powerful love.
Interesting play on the words "well" and "hole". God is a fountain of love, a spring of living water, etc.
However, as I understand it a black hole is more of a gravitational sink than a source. If you want to suggest that hell represents black holes, a better analogy would be going down the plug-hole. Unfortunately, the Bible doesn't use that imagery.
