If it were possible to travel to one of those distant places by moving towards the past and becoming part of it, then what would be seen from there would be our past, a reflection of a reflection, already changed from its measured image, in constant motion from instant to instant, passing through time. Nothing new, a thought conceived by many, perhaps with a “warped” drive for celestial conceptions.
