Oh, err... no offense but i'm going to designate myself project leader since there was actually some scientific reasoning for my suggestion.
Yeah, but it's you making it. I'm going to have to be chief project co-ordinator and co-ordinate you to make the tea.

You do realize there's only two of us in on this project? One of us is going to have to make something (other than tea)
If I put that through Babel Fish, is there any chance of it making sense?
Out of interest, with your suggestion of us being in another galaxy in 250 years time. When would that mean we'd be setting off on said journey? ie: So we're sitting here on Earth, and your rocket launches when? And you see it travelling for how long to get 25,000 light years away?
And you're happy with us being able to break all know laws of physics in such a short time scale?

So true. Even when you go back just 20 years, think of where the human race has gone.
20 years ago, if somebody had been told that information of any type shall be available with such ease (via the internet), with no wires (wireless connection on a laptop), people would've locked you up for being insane.
30 years ago, if people had been told that you would be able to contact virtually anyone on the face of the planet, from anywhere, using a personal communications device (mobile phone), they would've told you that you had watched for too many sci fi movies.
Also consider that the rate at which technology advances is actually accelerating.
Determined to prove the size of your e-penis aren't you? I've now shown humility several times to give you the ego trip you obviously needed and you just wont stop trying to prove your superiority.
You want some real physics?
According to Einstein's now pretty factual General Relativity and Special Relativity for anything to travel at the Speed of Light it would require an infinite amount of energy. To say anything else is to disagree with every real scientist in the world.
Both the Laws of General Relativity and Special Relativity dictate that 'effective' (i.e. literal) NTL or FTL travel is impossible whereas the laws do permit the possibility of 'affective' FTL travel whereby we 'cheat' to achieve the effect of travelling at FTL or NTL (e.g. via Black Holes or Wormholes, the latter of which is entirely theoretical and up to now; fictional).
Current theories to 'break' these laws includes the use of anti-matter v matter combustion which provides a 100% efficient energy conversion. However what these theories don't reveal is that you would need ~7bn kg of matter-anti-matter fuel to even reach half way through our own galaxy.
Now we also come to the subject of Time Dilation which is very popular with yourself. Miniture Time Dilation is a proven 'deal', it happens and we know exactly what its effects are. Extreme Time Dilation however has never been experienced and while I don't doubt its existence we still don't know its effects in totality.
If a non-manned probe was (hypothetically) sent at NTL or FTL speeds to some neighbouring galaxy time dilation would have no effect - there woud be nobody on there to experience it.
If a manned ship was (hypothetically) sent at NTL or FTL speeds to some neighbouring galaxy, the very thing that would make those astronaughts able to arrive in their lifetime (time dilation) would be the very thing that made the trip completely wasted. By the time the ship reached its destination the galaxy would have drifted (current understanding of galaxy movements) and Earth would be dead.
Best lolfest ever at people trying to deny any kind of close-to-light travel in 250 years without any proof AT ALL.
Ignorance is popular I heard

It's not our job to back up Einstein, it should be your job to prove you're smarter than him. I'm looking for the rolleyes emote that turns my eyes so far back that I swallow them but I can't seem to find it.
You jaded, cynical old gi... hang on you aren't even out of uni yet!
You don't have to be old to be jaded and cynical - or what I like to call; a realist. Cheers though

Your missing the point.
All I was asking for is physics that say going to another galaxy is impossible.
I haven't really said anything about FTl travel other than it's mathematically possible with an a Alcubierre drive which doesn't break general relativity laws, as you are still travelling slower than speed of light in your frame of reference. I don't believe anti matter - matter reactions is proposed as FTL travel. It is the same as a nuclear pulse drive, but with speeds about 50% speed of light.

Could we not harness solar energy? This would be (almost) an infinite power source.
As we develop as a race, I'm pretty sure solar power will become more prevalent and this should lead to more efficient means of harnessing solar power.
And if we do get closer to the speed of light, the passengers on board, should experience time at a slower rate, hence reducing their aging.
With regards to galaxies drifting away and the space ship heading to the wrong location, we shall need to develop an AI, which is able to correct the course of the ship. I course correction AI shouldn't be too difficult to achieve.

You can't exactly say its impossible in 250 years. We're just guessing or wanting it to be that number. What if we land on mars in 30 years and find out some spaceships which will propel our own understanding thousands of years forward.
If theoretically its possible, if the laws of physics are not preventing it then it is possible. Who knows maybe in 100 years we'll perfect the worm holes. Is it likely? Probably not but there is a chance.
You don't have to be such a nazi when it comes to wishful thinking of others. I understand if theoretically it was impossible to get to the nearest galaxy then you can explain to people as to why it won't happen in 250 years but if it is possible with our current understanding of the world then well who are you to say what we will achieve or not?
Bottom line we're all pretty much wishfully guessing when we will get to another galaxy, there is no need to impose your "realistic view" onto others. If everybody was a "realist" humanity wouldn't achieve the heights we got to.
Be a visionary.
edit: just in case you think I've got my head in the clouds my personal view is rather pessimistic and I can't comprehend(as in I know it exists but I can't come in terms that it is truly possible) the ability to travel backwards or wormholes for super travel across the space but good thing we're not in charge of innovation, right.

I thought the current understanding was that the use of wormholes would be physically impossible due to feedback closing it before you would have a chance to go through it, or even make it big enough.
The laws of physics are not permitting it, and many common sense issues stand in the way too. Hence my skepticism when someone just suggests, 'yes, in 250 years our ships will happily be in ANOTHER GALAXY!' Something that takes even light 25,000 years?!
Obviously the amount of energy to even reach near light speed are immense! And then there's all the problems of micrometeoroids, radiation etc etc etc. So even getting a probe to a nearby star within 250 years will be a push, yet alone another galaxy!
Yes, it's nice to wish things are possible, but unless you try to keep one foot in reality and make educated/calculated suggestions, it's nothing more than dreamland fairly tales.
From my noddy understanding, wormholes (if they exist) would be smaller than atoms in size, so would need to be expended, and held in place, and then travelled through...
So it's a pile of if's on maybe's on highly unlikely's...

Yeah, it was on a Hawking program i believe... as you increase the size you increase the feedback of the wormhole which leads to it closing. Rubbish explanation i know, but still
Who's got android phone?
Download the time dilation app
And see. How many years to travel 25000 ly at varying speeds
Like 99.99%
99.9999%
99.99999999%
99.9999999999999999%
As for wormholes that was on through the worm hole the other day. Or maybe one of the other ones. Would require Physics to be correct which is doubt fall and for you to obtain massive amount of anti mavity matter, which may not exist.
Found anonline calculation.
A constant acceleration of 1g and a constant deceleration of 1g you could travel 25000ly in smidge under 20 years. Assuming online calculator is correct.

Is that the general consensus of the scientists that travelling to other galaxies given current understanding of the laws of physics is theoretically impossible? If the answer is no then the person who said 250 years should not get all the abuse as its his guess of the future vs your guess be it a calculative guess.
If the answer is yes on the other hand, then sure thing, its impossible to reach another galaxy with a probe. Its just my understanding (which is not complete obviously) is that it is theoretically possible apparently.
What matters to me is what the consensus of the boffins is rather than "realistic" outlook of a randomer on the interwebs

Show me any article, by anyone one wwith serious knowledge or understanding suggesting we could even leave OUR galaxy in 250 years, yet alone be another one...
Then we'll start talking about who's being serious!
I used the app:
It stated at 99% speed of light to travel 25k light-years, it would be 25,252yrs, 191days, 17hrs, 12mins, 43.6sec time passed as experienced by a stationary observer at the point of origin.
It would be 3562yrs, 112days, 1hr, 53mins and 40secs as experienced by a moving observer in the Space craft.
Gotta love Time Dilation at relativistic speeds.
Moon - zzzz been there
Mars - zzz boring
Jupiter - zzz boring
Star - its a star, zzz boring
Galaxy - woaw, but never.
I think the most interesting thing out there is Jupiter's moon europa. I think there would be loads going down.

Why would there be such an article. We haven't got the drives at the moment. But if you see my post above if we had the perfect drive it takes just 20years.
So it certainly isn't impossible, I agree extremely unlikely in that timeframe. But certainly not impossible.
