Riding light

Someone made a movie of what it would look like to travel through space, as if hitched to a photon (a particle of light), but looking back toward the sun. The movie is totally unrealistic of course, since we couldn't ever accomplish this ourselves and you couldn't possibly pass every planet travelling in a straight line.

But consider that it takes light 1.3 seconds to travel from Earth to our own moon, then watch this movie to get a real sense of the massive distances between the bodies in our inner solar system and the massive size of our sun.
