Dear /sci/

I have a challenge for you:

if lightspeed means travelling 300 000km per second and one lightyear is 9500 000 000 000km (9.5 billion) and the closest solar system: Gliese 876 is 15 lightyears away, how many years would it take us to reach Gliese 876 in lightspeed?

It interstellar travel possible even theoretically? What would we need to do to make it possible? How viable would it be? If it is theoretically possible, how far along do you think the human race is?

I know there have been talk about shit like worm holes, time dilation, ect... but how viable is any of this really? Assuming we don't destroy ourselves, and manage to survive long enough.. can mankind really travel the stars?
