Exactly ! well said in bold. Where there once was a declining gravity gradient, you have have now, to use your words "more concentrated"* gravity,-- In that same space. More concentration means more , like in "where is more gravity, inside or out?" *perhaps more tensioned space. or gravitons, "muscle pulling", whatever. so: If the size of space has not changed, but the content (projected into) has, how can you maintain that the total has not changed, ? gravity is not energy.
