But, one huge caveat. Seeing the Milky Way as it was at the time of the dinosaurs is not the same as actually being able to see individual dinosaurs! Using current technology, astronomers cannot resolve any details on even the biggest planets orbiting the nearest stars. Dinosaurs are much much smaller than a whole planet, and NGC 4845 is millions of times farther away. Even the wildest theoretical technologies that anybody has ever imagined (such as using the Sun as a magnifying gravitational lens) would not be nearly powerful enough to see dinosaurs on Earth from such a great distance. By the time you get that far away, there are almost no photons (particles of light) left to collect, which means there is no obvious physical way for any aliens in NGC 4845 to reconstruct pretty pictures of old T. rex getting mowed down by an asteroid.
