I found this really cool video entitled, "If You Could Tour The Solar System At The Speed Of Light, It Might Look Like This".
I think the video best shows the vast distances between the planets in our solar system.
The video, however, interpreted in an Einsteinian way of what it's like traveling at the speed of light might be flawed.
Let's say I can travel at the speed of light and at the start I am looking at the sun just like the video begins. The sun would not get smaller as I traveled away because that implies the light from the sun changed which it couldn't since the changed light would have to travel faster than the speed of light to reach me. And yet according to Einstein the speed of light is the absolute speed limit of the universe.
So once I start moving away from the sun at the speed of light, the sun wouldn't change in appearance at all. It would be like a still photographic snapshot of the sun the moment I reached the speed of light until I stopped and the light caught up with me. Or maybe it would be black looking backward since no photons could catch up and hit my eyes, but bright looking forward in the direction of my travel. The tour would be a very boring trip--at least looking backwards.
So the video is best interpreted as what the universe looks like while traveling at "nearly the speed of light". As the light catches up with me, the sun would become smaller and dimmer at a rate determined by my sub-light speed. It's still an neat video!
