You are severely overlooking the point I am making
It's not just down to drives of course, it's everything else to permit such a journey! Huge power sources, shields, and goodness knows what else!
And, to get to another galaxy? For everyone here back on earth it of course takes 25,000yrs for the probe to get there (even at the speed of light)... And then 25,000yrs for the signal to give us a thumbs up that it's arrived. So the thumbs up (got there) takes 50,000 years!
So someone talking about getting 25,000yrs away in 250yrs time, seems bizarre to me! Another star maybe? But another galaxy! Come on!
110 years ago, before air planes were invented/built/successfully tested, if you hard asked most scientists/knowledgable people about the future of flight, most would've told you that it is either impossible or at least 500-1000 years away.
Jut as you are ridiculing the concept of long distance space travel, you would also have ridiculed the idea of reliable (global) flight. You would have course, have been completely wrong.
Like the guy earlier said, if it isn't physically impossible, travelling to another galaxy in 250 years time, is possible. Unlikely...but possible.
what has time on earth got to do with time getting somewhere.
Surly we are going to take the time of the people on board, rather than on earth.
As for communication, that depends if things like quantum entanglement can work over large distances. But such a mission would be a one way colonisation mission. Rather than getting info or anything else back to earth.
All your assumptions are based on technology/knowledge of 2011. You need to use technology/knowledge of the 23rd century. By then, things that we think are impossible will be possible.
100 years ago, if you had asked how long would it take to travel to the other side of the World, you would've thought, "by ship it will probably take about 4 weeks.
In 2011, if I asked you the same question (using the knowledge/technology we have to day), you would say "less than 1 day".
Why? Are you suggesting the first mission to another star, or galaxy, would be manned? Surely it would almost certainly be a probe without needless delicate biological passengers on board creating even more problems for the success of the mission.
So, I think the time on earth is the only thing worth talking about TBH...
I find it highly unlikely to be a probe due to time dilation. It would IMO be a colonisation mission, after successful colonisation of other star systems in our galaxy. What is the point of sending a probe when it would take so long to find anything out. Humans on the other hand by that point would have spread itself over a sizeable chunk of the milky way and have more than enough experience. Wet ere that would be 300 years or 10000.
To another star would make more sense for a probe as it can be done at a speed time dilation isn't a factor.
To another star would make more sense for a probe as it can be done at a speed time dilation isn't a factor.
I disagree. The first mission going out to another galaxy would have to be unmanned. After we have enough knowledge about what's "out there", we can send in a manned vehicle. Pretty much all space missions work in this manner:
1. send out unmanned probes and get data.
2. send more probes out to verify the data.
3. send space ship which is capable of landing some vehicle on the surface of a planet/moon, etc. Then get samples and send back data.
Once everything checks out:
4. send a manned space vehicle.

Can i just say that in 250 years we still won't have explored a tiny portion of the Milky Way, never mind Andromeda (assuming that's your target, since it's the closest and it's getting closer). Depending on how things go, with finding other life, over here - i'm not sure there would be any reason to actually do it.
This isn't a normall space mission, it has time dilation built in.
If we are sending a ship to another galaxy, we will of already mastered sending humans to other stars.

In which case why would they visit us in the first place?
because they can and have better technology
I didn't know they existed and on top of that were far more advance than us. must have missed that press release.
Wow. Don't you think we have done a damn good job so far.
Look how far we have come in such a small time compared to how long the universe has existed for over a billion years.
Even better the fact that the cradle of civilization that in Mesopotamia emerged around 5,000 BC.
hypothetically or theoretically speaking obviously.
Again even if such species existed. You still have to think of time periods. Even if they survived 10 million years that still not a very good chance of being in the same period as our 160k
