Yea but then we go fast to another planet where there too we are vulnerable to super volcano's, global warming, drought, nuclear attack, meteors, the elements.We use anti-matter that can get up to 20% of the speed of light, build a ship that can support 3-5 people with shielding strong enough to take the beating.
