: For long-term survival, scientists are investigating propulsion technologies that could reach a "second Earth" in another solar system. This would require breakthroughs in speed and sustainability that currently border on science fiction.

: A more radical concept involves transcending our biological limits. By uploading human consciousness into machines or digital formats, "humanity" might survive in environments that would be lethal to organic life. Conclusion Through.the.Wormhole.S04E03.Can.We.Survive.the....

: Some theories suggest physically moving the Earth further away from the Sun using gravitational assists from asteroids or other celestial bodies to keep our planet within a safe temperature range. By uploading human consciousness into machines or digital

The episode establishes that while the Sun is currently the source of all life on Earth, it is also a ticking time bomb. In approximately 5 billion years, it will exhaust its hydrogen fuel and begin burning helium, causing it to expand into a red giant. This expansion will likely swallow Mercury and Venus, and at the very least, turn Earth into a scorched, airless rock. Strategies for Survival In approximately 5 billion years, it will exhaust

To avoid extinction, the episode highlights several scientific and theoretical paths for humanity:

: The most direct solution involves moving our civilization. Mars is presented as a primary short-term candidate for relocation as the Sun's "habitable zone" shifts outward.
