It would take too long to get anywhere. Alpha Centuri is the closest star to earth at just 4 light years or 23.2 trillion miles!. In the fastest spacecraft nasa has that travels at 17,500 mph it would take about 153000 earth years to go just 4 light years to reach our nearest star system! If we could travel at lightspeed it would be much quicker but only for those onboard. If you would be inside the spacecraft traveling at the speed of light, it would take you 4 years to reach Alpha Centuri. If you were on the earth waiting for that spaceship to get there and back to earth, something like 800 years would pass for you. This is because time slows down when traveling at very high speeds compared to a stationary object !!
