A light-year is a measure of distance, not time.
Can a human survive long enough to travel that distance? Not by any means known.
The fastest spacecraft ever built by humans (Voyager 1) is traveling at 17.23 km/s.
Light travels at 299,792 km/s. That means that a spacecraft would take over 17 thousand years to travel one light-year.
Incidentally, the nearest star which might have planets is over 10 light-years away.

∙ 13y agoTo travel a light-year in a decade would mean travelling at 1/10 the speed of light [if you disregard time needed for acceleration and deceleration. See discussion]. Current technology is nowhere near achieving this speed; while there are some speculations about future technology, for now, this is just that: speculation. It is hard to tell whether it will be possible in the foreseeable future.

∙ 14y agoYes. A light year is the distance light travels in one year and is a measure of distance or length. It equates to about 6 trillion miles.

Which star is the closest distance to the Sun 27.3 light years 11.9 light years 70.2 light years 59.5 light years?
if those are the only 4 options then the star that is 11.9 light years away is the closest
How many parsecs is 77.5 light years?
3.26 light years = 1 parsec 77.5 light years = 23.8 parsecs
How light years away is the arturus from earth?
36 light-years, or 11 parsecs.
Why can you see stars that aren't there?
Because of the distances involved.If a star is 50,000 light years from us, we will only see it's light as it WAS 50,000 years ago. That star may no longer exist but we won't know for 50,000 years.
Why do robots exist?
because million years ago there was many robot there so they made it with metals and alecticity and light
Does Alpha Centauri exist?
Yes. It's the nearest star system to our Solar System, at a distance of about 4.3 light-years.
Do virtual images exist where no light rays can be found?
Yes, virtual images exist where no light rays can be found.
Does tron legacy world exist?
No, it is a complete fiction, but it might (give our take, I don't know 200-300 years?) exist in the future but it would require immense technological advances, and it would be unlikely it would ever exist. At least in the form it is in the movies (i.e disk fights, light cycles, light suits, etc.)
You only exist where there is light but when light is on you i take flight what are you?
a shadow?
How is light energy different from both sound and heat energy?
Light energy can exist independently of matter. *Studyisland
What exist as waves and particles?
light
Why do stars that don't exist still stay in the sky?
Stars that don't exist still stay in the sky because the light that we're seeing in the sky is about 10 years old because it takes so long for the light to get here due to the stars being billions of miles away
