A light year is a distance; so the wording of the question is it's own answer:
1 light year (about 5 878 499 810 000 miles or 9 460 528 400 000 kilometers)
That distance would take about 58 784 998 100 hours at 100 mph which is about 6 706 166 years and a few months (which isn't all that long when you think that there have been human-like beings who could make tools and probably talk to each other for more than a tenth of that time).
Yes, a redshift of 5 does equal to a light travel distance of 12.5 billion years.
Probably not in five lifetimes! Light speed travel is a work of fiction, like in sci fi movies. No human will ever travel at the speed of light.
Yes, a redshift of 0.6 does equal to a light travel distance of nearly 6 billion years (i.e. 5.7 billion years).
Yes, a redshift of 3.25 does equal to a light travel distance of nearly 12 billion years (i.e. 11.7 billion years).
Yes, a redshift of 7 does equal to a light travel distance of nearly 13 billion years (i.e. 12.9 billion years).
They travel to the speed of light? to it? and where exactly is the speed of light?
Because they are light.
Yes, a redshift of 8 does equal to a light travel distance of 13 billion years.
Yes, a redshift of 5 does equal to a light travel distance of 12.5 billion years.
Probably not in five lifetimes! Light speed travel is a work of fiction, like in sci fi movies. No human will ever travel at the speed of light.
