What if our planet becomes unlivable and our future selves decide to take to the stars in the hope of starting all over again. Where would we go?
Mars could be a good choice as it's the most habitable world beyond Earth in our solar system -- though it would be a struggle.
But say if we found a planet, not too dissimilar to Earth, orbiting a nearby star? Could that incentivize us to not only become an "interplanetary
species" but also an interstellar one?
