Only 20 light years?If we use our best technology we can be there in only 300 years
not 300 years! its actually 300k+.
Livable Alien Planet Finally Discovered

No, I already said something about that 3 posts ago.
The main bottleneck is the energy source. Rockets burn out in minutes, they are useless, we need constant power delivery for the whole trip. Maybe a mini fusion generator can do the job a few decades in the future. Nowadays fusion generators are a bit bulky, like 12 times man size. And their output is poor, most of the fuel goes into keeping the plasma blob alive, which also works only for a few seconds on the profitable pressures before the system collapses due to slowly reacting containment field control computers. The latest test reactor - ITER - in Europe sets this goal to a 400 second stable plasma flow while getting a net power output over 0 the whole time. More pure brutal computing power is needed to regulate a containment field that can manage the fluctuations in higher and more profitable plasma pressures. And we will get this power for sure. The video gamers pay for its developement.
Here some pocket calculator games for these who are really interested. With some surprising results. As it's only 20 ly, it can be done in a human lifetime. Even if you are not onboard the ship.
Edit: I can't post links here with my low post count, so use the first google hit for "the relativistic rocket".

Mazlan Othman Named Ambassador to Theoretical Extraterrestrials
http://nymag.com/daily/intel/2010/09/mazlan_othman_named_ambassador.html
The United Nation has appointed Mazlan Othman, a Malaysian scientist, head of Earth's Office for Outer Space Affairs. She's expected to announce her new role at a conference next week.
"The continued search for extraterrestrial communication sustains the hope that someday humankind will receive signals from extraterrestrials," Othman said.
"When we do, we should have in place a coordinated response that takes into account all the sensitivities related to the subject." First stop for aliens? Meeting her! Othman has a PhD in astrophysics, but more important, she does have a very warm-seeming face, like she's just going to give the aliens a big hug. [NYP]

Wow.. where can I apply for a job to sit and wait for a phone call I might never get the rest of my life?

Cant you all see they trying to find another planet so they can start another colony out there only of rich and smart people. Watch and See
Energy isn't that much of a problem, once you reached maximum speed, you won't need more...
accelerating costs energy, staying at high speed doesn't (well, except for pioneer anomaly).
And they currently consider spacecraft with one tenth the speed of light theoretically possible, so it would just be a few generations to a new earth...if mankind exists long enough to create such technology.
Meh, terraforming sounds easier. Off to Mars! :drinking8

I hope she not wear a cloth over her head and body as the aliens will not see her and she cannot give hugs.
Course we know mysterious history of Earth is covered up and they already here and from other dimensions
Finally hope she speaks English as aliens only speak English as a second language, even with telepathy!

well....
...a little 'relativity': The faster we travel, the more we weigh. As we approach the speed of light, our mass approaches infinity(and we squish down flat) - we're gonna need some insane amount of energy to accelerate! And consider decelerating...how much energy would we need to slow down a near-infinite mass??
Unless we can convert ourselves to mass-less waves, there is no way of even getting close to the speed of light...

Light year is measure in distance, not time.
Light of speed = ~300000 km/sec
1 light year = 9,406,052,840,000 km
Helios 2 holds the record for the fastest man made object at just over 158,000 mph or 254,276km/hr.
Distance that helios 2 can travel in a year = 254276 * 24 * 365 = 2,227,457,760 km
helios 2 takes 9406052840000/2227457760 = 4222.7 years to travel 1 light year distance.
helios 2 takes 84454 years to travel to 20 light year distance.
