In reading an article on the DNA of the human body it was stated that the DNA in one cell,if stretched out, was 6 feet long.If you were to extract the DNA from all of your body's trillions of cells and place the strands end to end,the total length ,according to some estimates would be nearly 670 times the distance from the earth to the sun(93,000,000,000 miles,1 time) and back.To travel that distance at the speed of light(186,282 miles per sec)it would take 185 hours.
My question is this: multiplying the time(185 hrs) it would take to travel to the sun at the speed of light,a number with how many zeros would be produced? I have no way to calculate such a number.What would be the method?
