    A light year is one where the extra cool blessings surpass the heartaches. 

    A year when the sun does not set,,up there with the blue moon theory..>>>>>>>><<<<<<<<..

    ""

    299,792,458 meters per second or 186,282 miles per second.


    186,282X60 seconds=11,176,920 miles per minute.


    X 60 minutes=670,615,200 miles per hour


    X24 hours= 1.609476e+10 miles per day


    and finally X 365 days= 5.874589e+10 miles per year

    Light year ( In Astronomy ) The distance travelled by light moving in a vacuum in the course of one year at its accepted velocity of ( 299,792,458 Metres per second )

    1 light year is the distance traveled by the light in 1 year through vacuum.


    So, 1 light year = distance traveled by the light in 1 year


    But, distance traveled = speed of light × time taken


    = 3 × 10 raised to the power 8 × 1 year


    But 1 year = 365 days = 365 × 24 hours = 365 × 24 × 60 minutes = 365 × 24 × 60 × 60 seconds


    So, 1 light year = 3 × 10 raised to the power 8 × 365 × 24 × 60 × 60


    i.e. 1 light year = 9.46 × 10 raised to the power 12 kilometer or 9.46 × 10 raised to the power 15 meter [Approximate value]


    Now share the above information with your friends too.

    aborb, This is the only answer that makes sense .

    Two years later in 1998 link Parmigiani link Fleurier offered a 96-page catalog of watches don't worry I read all 96 pages so you don't have link to with a keen focus on unique styling of classical shapes and a best-in-class level of finishing The catalog boasts of Parmigiani Fleurer's "international network of demanding collectors and art lovers" and carrying "heritage and tradition forward." In these early years it's estimated Parmigiani Fleurier was producing fewer than 1000 watches per year.
