Just to put this into perspective, the Speed of light travels at a speed of 186,000 miles a second or 700 million miles an hour. The space shuttle only travels at about 5 miles per second or 17,500 mph. To put THAT into perspective, next time your in your car, note how long it takes you to drive 5 miles and then realize, the space shuttle can do that in 1 second.
From a scientific point of view, light from the nearest star, other than the sun, (Proxima Centauri), takes four and a half years to get here. Thus, when you look up into the sky at night, none of those stars you see are there anymore. It's a direct window into the past. How's that to boggle the brain?
