Our nearest star - 35 trillion miles away...How Far is that?

In perspective, a train going at the rate of a mile a minute would reach our nearest star in 48-million years. Make you think doesn't it. How will space travelers reach it?
If a song were sung there and the sound traveled here it would be 3,800,000 years before it reached us so that we could hear it. So much for crooning to your love, pining your heart out for her.

How about something lighter? A spider's web - or at least the silken thread that she uses to build her web would weigh 500 tons by the time it reached that star. Amazing to think of.

And what great mind figured this all out in the first place?
I read about it in Dale Carnegie's How to Develop Self-Confidence & Influence People by Public Speaking.
