Even at the highest speeds physics allows, a journey to the nearest star would take decades in the best case, centuries in more realistic scenarios. One proposed solution is to put the crew to sleep — to slow the body's metabolism so dramatically that the traveler barely ages. The biology is real; the engineering is the challenge.
Could We Build a Self-Sustaining City on Mars This Century?
Elon Musk has said a million people on Mars within a century is his goal. That is an audacious claim, but the underlying question — what it would actually take to build a city that cannot depend on Earth for survival — is one of the most fascinating engineering and social problems of our time.
Generation Ships and the Centuries-Long Voyage to Another Star
The nearest star system is so far away that any realistic spacecraft would take thousands of years to arrive. Generation ships — self-contained worlds carrying thousands of people across the void — are the most serious solution anyone has proposed.
