A wormhole 10 billion light years long! Wow, we could only see the target galaxy if there was a quasar there (which Gargantua could well be). And, from that end, you would never find the Milky Way in a telescope – we don’t really have much idea what it looked like 10 billion years BP. (For example, it probably didn’t have any spiral arms back then.)
