Given a spaceship, equipped with the most advanced technology of today, how much time would it take us to travel 1 ly?

how ever long it would take the space shuttle to travel 1 light year

>> No.3434954

how long is a light year in hours?

Light years measure distance, not time.

You could do it in as little time as necessary, if you're able to travel fast enough.

For example, if you were to travel at 99% of the speed of light relative to the Earth, you would (from your perspective) be able to do it in 0.1425 years, which is about 52 days. From Earth's perspective, you would have traveled the distance in 368.7 days.

How long from who's reference frame? Time is not the same for all observers.

I think what OP is asking is, in essence, "Today, in 2011, what is the fastest rocket/[other means of propulsion here] that we've got?"

For the traveller, obviously.
