Becoming an Interstellar Species
Isaac Arthur・27 minutes read
Becoming an interstellar species presents challenges due to vast distances, but genetic engineering and diverse environments could expedite the process. Various propulsion methods and colonization strategies are explored, emphasizing the need for careful planning and collaboration in interstellar travel.
Insights
- Genetic engineering and exposure to diverse environments can foster species diversity faster than interstellar travel, which would take billions of years at modern spacecraft speeds.
- Technologies like digital DNA copies and printed DNA strands offer potential solutions for interstellar colonization without the need to transport living organisms, showcasing innovative approaches to space exploration.

"Slowing ships for colonization, laser pushing dangers"
- Ships need to slow down to colonize, with one ship meant to slow down and another not, which can move twice as fast.
- Slowing down is necessary for colonization but not for ramming, as speeding up causes more damage.
- Ships using rocket fuel can be easily detected and destroyed by pursuing craft with the same propulsion design.
- Pursuit ships have an advantage in maneuverability and detectability due to their drive orientation.
- Laser pushing can make ships more detectable and less maneuverable, allowing for attacks or energy blockage.
- Interstellar colonization races can occur, but hostility can lead to easy retaliation and ship destruction.
- Space is vast, with over a thousand stars within a volume ten times wider than 4 light years.
- Various methods of colonization exist, including sending minds via hard drive or using artificial intelligence.
- Von Neumann probes can replicate in systems, with the intelligence level depending on programming.
- The fastest way to another system is the laser pushing system, but slowing down on arrival requires a crash project with solar sails and laser beams.
