How many seconds are in a lightyear?

Answer 1

The same number of seconds as in any other year.

Answer 2

Your question is unanswerable, because they are not the same sort of thing. Seconds are a measure of time, and lightyears are a measure of distance. One light year is the distance that light will travel in one year, which is 5.559×10^15 miles.

In essence, you're asking how many minutes are in a mile. The answer is, depends on how fast you're travelling.

Answer 3

None. A lightyear is a measure of distance, not time. It's the distance light travels in a year.

Answer 4

Although a light year is a measure of distance, there are approximately 365.25 x 24 x 3600 = 31, 557,600 "light seconds" in a light year. Maybe that answers your question.

Answer 5

365.25*24*60*60

Lightyear is both a measurment of distance and time when you are dealing with Minkowski universe,they use ct as the time coordinate so that the light cone makes an angle of 45degrees with the time coordinate and the Euclidean 3-D hypersurface.

Answer 6

Lightyears measure distance, not time.

Answer 7

Here, you work it out:

1 year = 365 days
1 day = 24 hours
1 hour = 60 min
1 min = 60 sec

You now have everything you need to know to answer your question. Hint: your answer does not depend on the speed of light.

Answer 8

alight year is not a unit of time but rather a unit of distance. A light year is the distance that light can travel in a vacuum in one year. alight second would be the distance light travels in a vacuum in one second. A light week is the distance light travels in a vacuum in one week etc.

It is the same concept of the Manhour. it is not realy an hour but really the amount of work one person can accomplish in one hour. two people working for one hour would be two manhours.

Answer 9

365 days 5 hours 49 minutes


31556940 seconds

Answer 10

lightyear measure distance , not clock
