Explanation: What would it look like to travel near the speed of light? Strange visual effects would appear as documented in the above relativistically-accurate animation. First of all, relativistic aberration would cause objects to appear to bunch up in front you. Next, the Doppler shift would cause the colors of forward objects to shift toward the blue, while things behind you would shift toward the red. Similarly, the world in front of you would seem to move unusually fast, while the world behind you would appear to slow down. Objects to the sides will appear rotated, possibly enabling surfaces normally hidden from you to become visible. Of course, since constant motion is relative, the same effects would occur were you to remain stationary and the entire world advanced toward you.

Looks like a description of a near-death experience.

I’m guessing that headlights on a car traveling the speed of light would be useless.......

Some of you may remember Carl Sagan's 13 part series entitled "Cosmos". Episode 8 was entitled "Journeys in Space and Time". It dealt with Ideas about time and space which are explored in the changes that constellations undergo over time, the redshift and blue shift measured in interstellar objects, time dilation in Albert Einstein's theory of relativity, the designs of both Leonardo da Vinci and spacecraft that could travel near light speed, time travel and its hypothetical effects on human history, the origins of the Solar System, the history of life, and the immensity of space.
Here is that episode on You Tube (preceded by a commercial, of course).

I replied before you posted, but my post didn’t appear in this dimension. Dang.
