when i look at the hour-hand of my analog watch move, which it appears as if it is not moving, it is as if i am looking at a ray of light move at the speed of 2.99792458E8 meters per second a distance of 1.29510341856E13 meters, relatively speaking. in other words, the distance around my analog watch, for the hour-hand of the watch, is as if it were 1.29510341856E13 meters around if the hour-hand of the watch were a ray of light. 1.29510341856E13 meters is the distance a ray of light covers in 12 hours. > when i look at the hour-hand of my analog watch move, which it appears as if > it is not moving, it is as if i am looking at a ray of light move at the [quoted text clipped - 3 lines] > meters around if the hour-hand of the watch were a ray of light. > 1.29510341856E13 meters is the distance a ray of light covers in 12 hours. Hmmm... I get 1 meter in 3 nanoseonds. Maybe you need a smaller calculator. :o) Sue... i get one meter in 1/299,792,458 seconds (aprox. 3 nanoseconds), the same as you, but 1.29510341856E13 (1.29510341856 * 10^13) meters in 12 hours. it takes 12 hours for a ray of light to cover 1.29510341856E13 meters, the same as the hour hand to go once around my watch. so when i look at the hour hand move once around the watch, it is the same as if i am looking at a ray of light cover 1.29510341856E13 meters around, relatively speaking. francisco... > Hmmm... > I get 1 meter in 3 nanoseonds. > Maybe you need a smaller calculator. :o) > > Sue... > i get one meter in 1/299,792,458 seconds (aprox. 3 nanoseconds), the same as > you, but 1.29510341856E13 (1.29510341856 * 10^13) meters in 12 hours. it [quoted text clipped - 4 lines] > > francisco... Is that in someway different than the calculation we would make for the more common term "light year" ? Sue.. > > Hmmm... > > I get 1 meter in 3 nanoseonds. > > Maybe you need a smaller calculator. :o) > > > > Sue... a light-year is the distance (9.454254955488 * 10^15 meters) light travels in one year. the earth takes one year to orbit the sun. to look at the earth orbit the sun is the same, relatively speaking, as to look at light travel 9.454254955488 * 10^15 meters. imagine you are a big giant who is able to look at the earth orbit the sun. that would be the same, relatively speaking, as if you were a much bigger giant who is able to look at the tip of a ray of light travel 9.454254955488 * 10^15 meters. > Is that in someway different than the calculation we would make > for the more common term "light year" ? > > Sue.. > a light-year is the distance (9.454254955488 * 10^15 meters) light travels > in one year. the earth takes one year to orbit the sun. to look at the earth [quoted text clipped - 3 lines] > speaking, as if you were a much bigger giant who is able to look at the tip > of a ray of light travel 9.454254955488 * 10^15 meters. OK I thought that is what you were saying. I don't want to argue with someone that has a bigger calculator than I do. :o) Sue... > > Is that in someway different than the calculation we would make > > for the more common term "light year" ? > > > > Sue.. what is "a bigger calculator"? >> a light-year is the distance (9.454254955488 * 10^15 meters) light >> travels [quoted text clipped - 19 lines] >> > >> > Sue.. > what is "a bigger calculator"? Here is one http://www.googleguide.com/calculator.html But the instructions take forever to read. :-) Sue... > >> a light-year is the distance (9.454254955488 * 10^15 meters) light > >> travels [quoted text clipped - 19 lines] > >> > > >> > Sue.. |
