Traveling at the speed of light, 186,000 miles a second, is impossible. Too bad. The moon is only a quarter of a million miles away. At the speed of light, you could get there in less than a second and a half. The light from the sun takes eight minutes to travel the 93 million mile distance to earth. Pluto is about four and a half light hours away. Frozen comets at the edge of our solar system, perhaps a trillion miles out, are nearly ten weeks away at speed-of-light travel. After that we come to the star Alpha Centauri, a little over four light years distant – that’s 25 trillion miles. The farthest stars in our Milky Way are over a hundred thousand light years away – that’s about 600 thousand trillion miles - and the nearest big galaxy, Andromeda, is maybe fifteen million trillion miles out – 2 and a half million light years. And the most remote quasars are over 12 billion light years away – 90 billion trillion miles – far out!
