Hello Out There!

Read on today's paper that NASA is beaming Beatles' song, "Across the Universe" to the North Star. What amazes me is that even traveling at the speed of light, it will still take 431 years for any aliens living on the North Star to receive and hear the song. The North Star, Polaris, is 2.5 quadrillion miles away.

That's 2,500,000,000,000,000,000,000,000 (24 zeros) miles!!!

Just think, by the time the aliens receive the transmission of this song, we will all be history. What will our world be like 431 years from now? Will we know that some aliens out there finally hear us? Will they like the song?

Likewise, what if we receive a song from another distant planet now? How long did it take for it to get to us? What was their world like back then and now? What is Past, Now and Future??? In the space continuum of the universe, it doesn't seem that important.

My brain hurts...
