Expansionism and Opportunity in a Vast Universe (part 4)


Though current data and predictions aren't entirely conclusive, the chances a catastrophic impact with an asteroid could occur are around once every thousand years. In the future, if such a case is forecast, earth inhabitants might have another reason to relocate. There are a number of other events that could cause earth to become uninhabitable, so exploration to find other worlds to colonize would become a greater priority if a disastrous event was determined for the future. Other catalysts that might cause off-world colonization to become a priority could include a massive nuclear war, extreme pollution, a deadly outbreak, or even an encounter with an advanced alien species. It is difficult to say what might compel us to make another world our home, but more and more, it appears closer on the horizon.
