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

Well, ..., at the speed of light it would take 1 Billion years. Currently, it is not possible to exceed the speed of light and we certainly don't have the technology to accelerate ourselves even even close to it.

A minimum of 8 trillion hours, roughly.

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.

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.

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.

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...

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.

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.
