Light speeds along at nearly 300,000 kilometers per second (or 299,792.458 km
to be exact). That is about 180,000 miles per second. Despite the extremely fast
speed of light, sunlight still needs more than eight minutes to reach the earth.
If one could turn off the light of the sun at this very instant, we would only
experience the total darkness eight minutes later. Sun and earth are separated
by what is called eight light minutes. If one thinks about it that myriads of stars
are millions of light YEARS from the earth, one gets some impression of how
immense the universe must be.
