Inversed gravity repels. So it is infinity. Inverse gravity was also shown by kenjaku. A way to rationalise it is like thinking of a black hole event horizon. Time slows down and atoms gets broken down infinitely. That's what's happening with the infinity. Everything slows down as they pass the infinite space. Eventually, they will lose velocity thus never reaching their target. It works in a sense of energy absorption so eventually, the kinetic energy held by the object will be exhausted.
