Visualisation: there is always a time delay from setting out to arriving: When you look up into the sky and see the stars, what you are actually seeing is the past because some of those stars may no longer exist. This is possible because stars are hundreds and thousands of light years away, meaning that it takes their light, travelling at 186,000 miles per second, hundreds of thousands of years to reach earth. Thus the light we see from a star a hundred light years away is actually light it emitted a hundred years ago. That particular star could have exploded and disintegrated twenty-five years ago, but we still see its light, and will continue to see its light for another seventy-five years, even though the star itself has longed ceased to exist. Similarly with our visualising: The point is, there is always a time delay from our setting out to arriving.
