Let me make sure I've got this right. One night in December - in the middle of the rainy season - Joseph returns home from work and announces to his wife, Mary (a young lass of thireteen or fourteen in her ninth month of pregnancy) that they must immediately depart for Bethlehem in order to fulfill some vague scriptural prophecy. It's a journey of over one hundred and thirty kilometers that passes through some of the most treacherous and hostile territory in all of Jerusalem. However, Mary, despite being jerked and jostled on the back of a jackass and struggling on foot through thick muck and mire, manages to complete this arduous trek without hemorrhaging, breaking her water, or using harsh language. No doubt this has to be another one of those take it on 'faith' stories, right?

At two-tenths the speed of light, dust and atoms might not do significant damage even in a voyage of 40 years, but the faster you go, the worse it is--space begins to become abrasive. When you begin to approach the speed of light, hydrogen atoms become cosmic-ray particles, and they will fry the crew. ...So 60,000 kilometers per second may be the practical speed limit for space travel.

Kilometers are shorter than miles. Save gas, take your next trip in kilometers.
