How far would it take us to get to a galaxy 1 billion light years away, in hours?

answers:
Fred say: At the moment such travel is not possible. In the distant future if such a thing was possible the human life form is fragile and needs long acceleration times. By the time your decomposed body made it that far.. there would be no Earth to return to. The Expanding Sun consuming the Earth as it expands beyond Mars orbit.
That would be on a time scale of billions of years, far longer that the life cycle of our sun!

Tom S say: Depends on how fast you can travel, and your frame of reference. Light experiences pretty much no time at all in traveling that distance, but if we "time" that trip for the light beam, it takes a billion years.
-
? say: At the speed of light it would take 1 billion years.
Multiply that by 365x24 to get hours.
We can not travel anywhere near the speed of light = 300,000 km / second
We can manage about 100 km / second
So also multiply the above figure by 3,000
so time to go 1 billion light years is 1,000,000,000 x 365 x 24 x 3,000 hours
Even going 1 light year is totally beyond our present technology.

Bill-M say: In hours?? There is not enough space to write a number that big.
It will take New Horizons about 16 Thousand YEARS to go ONE light year.
-
Ronald 7 say: One Second
At the Speed of Thought

Joan H say: Depends on how fast you can go.

G. Whilikers say: Time to travel 1 light year at the speed of light: 1 year
Hours per year (large scale): 365.25 x 24 = 8766
Hours to travel 1 billion light years: 8766 x 1 000 000 000 = 8.8 trillion hours.

Robert J say: The furthest space probe so far has take roughly 40 years to travel 120 AU.
One AU is roughly 8 light-minutes to that's about 960 light-minutes or 16 light-hours.
That works out to about 550 years per light year.
So; never, with present technology - nothing we can build could last 550 Billion years...
-
say: Should be easy, if we had a Tardis. Time and distance would not matter at all.
Since we are about ten thousand years or so from making our own, it would be a while, at best. Ask again then.
-
say: impossible to answer.
all those answers assume we can travel at the speed of light or have exotic tech.
forgetting the fact that no vessel or fuel source could last that long or that 'we'could possibly exist as a species after a billion years.
also a galaxy 1 billion light years away now is going to be more distant when we get there.
nonsense question and answers.
-
someg say: More than 17 hours, even in a fast rocket.
-
jonniebaby say: 8.8 trillion. Give or take an hour or two.
-
poldi2 say: If we travelled at the speed of light, it would take 1 billion years.
In hours that would be 8,766 billion hours.

Zardoz say: On a Vespa or in a Smart Car?
-
Steven J say: "How far would it take us..." If it is 1 billion light years away....that is a distance. That is how far it would take you...
-
Grundoon say: A light year is not time
