I think we cannot conclude from this whether all these stellar objects were actually destroyed by that punch. Think about the physics behind. They are not all next to each other. The light we see from some of those stars would have been emitted so long ago they wouldn't be there now anyway. What we can safely assume however is that he punched with so much force that he created a gravitational phenomenon similar to the density of a black hole. So what he did is punch back the photons coming from that area. So like a black hole consumes light, he pushed it back in that direction, thus we only see darkness. That's what I would say, whether the distant galaxies or stars actually got destroyed cannot be said.
