How come no one has answered you...I think they or someone had to come up with a unit to measure great distances in space, however they forgot about the seed of light in relationship with light reaching the earth. By this measure we or the earth can be seeing new sources of light, or life in some form every day, if the right humans look hard enough. Any how I'm stuck here on earth with nothing to do but work and pay bills. What a drag... I only wish we could travel the seed of light, but again it would not be fast enough to travel great distances. We need to travel the speed of light times one million to really see the outer limits. 186 thousand plus per second times one-million. Let me know what that figures out to be. I would appreciate it. Then again what would you call the answer and how would you slow down once you got there, wherever you were going to smell the flowers.... Really wild... Let me know your answer. I will work on it too.
Thanks, joe
