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.

Yes, light years are a unit of distance used to measure the vast distances between objects in space, particularly in astronomy. One light year is the distance that light travels in one year, which is about 9.46 trillion kilometers.

∙ 14y 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.

587 light years is a unit of distance, not time. It represents the distance that light travels in 587 years.
Where was Antarctica 500 billion years?
Antarctica did not exist 500 billion years ago as it was part of the supercontinent Gondwana which formed much later, around 550 million years ago. The land that Antarctica currently occupies was situated closer to the equator during that time.
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?
The star that is closest to the Sun at a distance of 4.22 light years is Proxima Centauri.
How many parsecs is 77.5 light years?
3.26 light years = 1 parsec 77.5 light years = 23.8 parsecs
604 light years in scientific notation?
6.04*102 light years
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.
Why do stars that don't exist still stay in the sky?
The light from stars that no longer exist can still reach us due to the vast distances of space. Since light travels at a finite speed, we see these stars as they were in the past. This phenomenon allows us to observe objects in the night sky that may have ceased to exist millions of years ago.
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?
What exist as waves and particles?
light
The distance from the earth to the cosmos kubasik galaxy?
The cosmos Kubasik galaxy does not exist in real life. It seems to be a made-up term. The distance from Earth to other galaxies can vary greatly, as galaxies are millions or billions of light-years away from us.
You only exist where there is light but if light is on you you take flight What are you?
Darkness Shadow
If there was no light on earth would color exist?
