Now that scientists have discovered evidence of thousands of other planets, the next question is, obviously, how can we colonize them? Keep these considerations in mind to become a colonial power of galactic proportion.
Step 1: Target a Goldilocks planet Target a planet in the so-called Goldilocks zone -- close enough to a sun so temperatures are neither too hot nor too cold but just right. This ensures that water would be available in liquid form.
Step 2: Figure out how to get there Figure out how to get there in this lifetime -- most planets are light years away. Circumventing the speed of light would be a good start.
Step 3: Pick an uninhabited one If possible, pick an uninhabited land. It's much easier to colonize a new planet without any alien life forms who could very well outsmart and overpower earthlings.
TIP: Renowned astrophysicist Stephen Hawking said that alien life is likely.
Step 4: Protect human fertilization Protect human fertilization. Scientists investigating the feasibility of colonizing Mars found that high levels of radiation in space would make pregnancy problematic. And negative population growth makes a planet pretty hard to colonize.
Step 5: Build housing Build housing -- man-made biospheres that allow people to survive on the new planet by providing closed ecological systems.
Step 6: Start terraforming Start terraforming -- changing the new planet's environment so earthlings can live outside their biospheres. Then, try not to pollute it too soon!
FACT: Scientists believe that as many as half the stars in our galaxy have planets that are two to 10 times the size of Earth and may sustain life.
