I have a question, is there time out in space ?
Yes....well there's actually spacetime everywhere. It's an Einstein thing....we seem to have a dearth of Einsteins on here though. Not sure it's worth trying to explain in depth.
If there is, how could we measure it ?
You measure time in space just like we do here on Earth, with a clock. As you move further away from the Earth's center of mass, your clock will go faster.....however if you start moving faster, through space, your clock will go slower. As I pointed out earlier, both of these time dilation factors have to be corrected for in the GPS system, otherwise your Iphone's maps wouldn't work.
Evolution has no reason for a week.
Uh....no....since evolution is a theory of biological organisms changing through history, not a calendar.
How come we all keep seven day weeks? Evolution has no reason for a week. Only one thing constitutes a week, In six days God made the heavens and the earth, and He rested on the seventh day and hallowed it.
Because our calendar grew out of the Roman calendar which was based on even older lunar calendars. The moon orbits the Earth every 28 days, leading to lunar "months" There's four primary phases of the moon which divided the lunar month into 7 day long weeks. The Romans named their 7 days for their 7 gods that flew around in the sky (Saturn, Sun, Moon, Mercury, Venus, Mars, Jupiter). The etymology of our names for Saturday, Sunday and Monday goes back to the Romans. The other day's names have changed over time.
Congratulations...your hallowed 7th day is named in honor of the Roman Sun god.....unless you're a 7th day Adventist, in which case your hallowed day is named for the the Roman god Saturn.
The Mayans didn't have 7 day weeks. They had two types of weeks, numbered weeks that were 13 days long and named weeks which were 20 days long. Guess their sky fairy was slower at heaven and earth buildin' than yours.
