The basic problems to overcome:

  • Distance, the closest is 4 light years, as we have not figured out how to travel as fast as light or faster, we will be many decades traveling there. It will take so long that the children or grand children will arrive, not the people that leave on the ship.
  • Living in a space ship for many many years without going crazy or dieing from radiation or other mishap
  • Power, as of yet we have not figured out how to power a ship that far and stop it at the far end. There a bunch of good ideas, but no tested system.
  • Money to pay for overcoming the problems above.
