Traveling at light speed, how long would it take to get to the nearest galaxy?

Answer 1

The closest galaxy is the recently discovered Canis Major dwarf galaxy, which is "only" 25,000 light-years away.

So it would take 25,000 years to get there if you traveled at the speed of light. Actually, that's the amount of time it would take from the perspective of the outside world. From the perspective of a traveler moving at the speed of light, it would appear to take no time at all. That's because of elativistic "time dilation",

Answer 2

First of all, fire princess of zor, we will never be able to travel at or faster than the speed of light, it's not like we haven't got powerful enough engines or something, but that anything with mass cannot travel at or above the speed of light. We can travel very close to it, say 99.9999% the speed of it, but as we get closer to it, the required energy to reacht the SoL increases proportionally to our increase of speed, and equally the resulting increase in our own mass. If we were to break the SoL barrier, not only would we have an infinite mass, but would have required an infinite amount of energy to get there. This is both physically and logically impossible, based on Einstein's theory of Relativity.

Which I guess kind of defuncts the question, but say you managed to get past all that and travel at the speed of light, we, a stationary observer, would see that it took whoever it was 25,000 years to get to the nearest galaxy, Canis Major Dwarf. Whoever was travelling at light speed though would get the impression that no time at all had passed, because if a person, that is, an object with mass, were to travel at the SoL, time essentially stands still, they would not age, everything contained inside their craft would freeze, clocks would stand still etc. which is why it is so mind boggling to imagine moving faster than the SoL, because the clocks would start to move backwards...

Very confusing, but hope this helps someone

Answer 3

because of the fact of relativity, the swifter some thing travels, the slower time passes for it. The quickest clever acceleration for a spaceship carrying human beings could be one that can grant on the subject of a similar rigidity on one's physique as Earth's gravity. If this sort of spacecraft is achievable, and it may prefer a _lot_ of gasoline, it may take possibly thirty years to get from right here to the Andromeda galaxy 2 million easy years away. as some distance because of the fact the persons left in the back of have been in contact, nevertheless, it could have taken hundreds of thousands of years.

Answer 4

it depends on what year you are travelling in
in later years we might (0.0001% chance we will) be able to travel at the speed of light, perhaps even faster. Then what we will do is be able to get to near galaxies in about 400 - 2500 years.

Answer 5

Possibility 50% traveling to nearest galaxy if Albert Einstein Still alive and do his work about the theory of Relativity(time and Space)or the fastest travel is the Unified Fields Theory of the Guy Einstein,

Answer 6

The nearest galaxy is thousands or more light years away from us.

Answer 7

Depends what you were in! A corsa would take about a million years ( half that to get it started!) and , of course, if you are a woman you would get lost or reverse into something on the way!

Answer 8

you don't need to travel at light speed, all shops stock the galaxy chocolate. Relax, sit back and enjoy.

Answer 9

400 years

Answer 10

25000 years according to wikipedia
