People hoping to travel to other worlds are faced with huge challenges. one of the biggest is the time required for a journey. the nearest star is 4.1×1016m away. suppose you had a spacecraft that could accelerate at 1.0 g for two thirds of a year, then continue at a constant speed. (this is far beyond what can be achieved with any known technology.)
