how many human years whould it take to travle one light year?

Question

i was thinking at a few thousand km/p...you know, how fast a space ship would go, on average....30 000km/p?

lol, i know a light year is a distance, duh....but becasue that distance is sooooo long, id like to know how LONG it will take to travle that distance, through space....how many years will it take a person to travle 40 light years if they are going at say, 30 000km/h.

Answer 1

At 1,000mps (3.6 Million miles per hour) 186 years.
At 30,000 km/hr each light second would take 10 hours.
At that rate 1 light year would take
3600*24*365.24
31556736
answer*10
315567360
answer/365.24/24
36,000 YEARS
40 light years would take 40 x 36,000 years.

Answer 3

Consider the speed of light is about 186282.397 miles per second or 670616629.384 miles per hour and 5874601673403.84 miles per year.

Now consider that most calculators will produce an error when you try to work this out...
... and you would die before being able to make it 1 mile at light speed.

A light year, however, can be counted according to a ratio if you'd like, which brings us full circle back to the beginning. In a vacuum 1/299,792,458 of a second constitutes light speed travel.

Simply divide the amount of speed you travel by the values you see above. At 60 miles per hour, you can travel 11176943.823066666666666666666667 miles at light speed.
As for how many human years, light speed is not measured as such. You still need a point of reference.

It's got nothing to do with how far you travel. It's to do with how fast you go. Lets say that you stayed on Earth and this other person went away for 40 years. If they travelled at half the speed of light then they would only age by 34.6 years compared to the 40 years that you would age. If they travelled at 3/4 of the speed of light then they'd age by 26.5 years and you by 40 years. At 99% the speed of light they'd age by 5.6 years. This is because as you approach the speed of light time itself begins to slow down bya factor γ given by: γ = sqrt [ 1 - v^2 / c^2] where v is the speed at which you travel relative to somebody else and c = speed of light. You may want to look up 'the twin paradox'.

Answer 5

How long would it take in dark years

Answer 6

1 light year is the distance light travels through space for a period of 1 year. Light travels at approximatley 176,000 Miles per Second. Man has not created anything that can travel that fast!

Answer 7

Well, that all depends on how fast you're going. If you were able to travel at the speed of light, obviously, it would only take you a year to get there. On the other hand if you were driving and only going 55, heck 65, it would take you practically forever.

Answer 8

It would take about 40,000 years if you use the shuttle. It would be more feasible to use an Ion Propulsion Engine to travel a light year, though. It would still take much longer than a lifetime.

Answer 9

Estimate: Light will travel 5,874,601,673,407.3 miles in one year. If an average person walks 3 miles per hour then it will take 1,958,200,557,802.43 hours or 81,591,689,908.43 days or 223,390,644 years to walk that distance

Answer 10

So since you know the distance of a light year, and you have an idea the speed of travel, how hard is it to calculate the time?
If you want to travel 100 miles and you travel at 50 miles per hour, then it takes 2 hours, right?
Same math to calculate your question.
