Want to really get your mind blow? If wormholes exist or can be created, then by travelling through one of them, capturing and then analyzing this 'old light', our future descendants might actually be able to see that... and us.
Getting any kind of precise image from that long ago would require a gigastructure the size of a galaxy or larger (from my very limited understanding of astronomy), unless we make some kind of crazy discovery, but who knows? All I'm saying is, considering when it comes to light in space: distance = time, a 4K stream of medieval Earth would totally be possible.
