Hop, Skip and a Jump versus Science Reality:
The most distant space probe, Voyager 1, was about 17 light-hours away from the Earth as of December 2012. It will take about 17,500 years to reach one light-year (1.0 ×100 ly) at its current speed of about 17 km/s (38000 mph) relative to the Sun.
Do the math. 17,500 years to get ONE light year away from Earth means twelve times that many years to get to this suspected habitable zone.
Roughly a couple hundred thousand years in your spaceship to get there.
We are in the only habitable zone that humanity will likely ever know at this very moment. Perhaps we ought to take a minute and look around to see if we are doing everything we can think of to try and protect it? Makes more sense than dreaming of an irrational escape from the living hell we seem determined to inflict upon ourselves in one form or fashion, be it in the form of global warming or the more upbeat happiness of a warm gun.
Enjoy.
