Study Notes
The Galactic Competition: Why We Might Be Early to the Game
- The universe is vast, but we see no signs of life, which raises the question of where everyone else is.
- Life needs to pass several hard steps to become a technological civilization, and we don't know how long each step takes.
- Life on Earth appeared quickly, but it took 2 billion years to pass from single cells to multicellular organisms and 2 billion more for humans to appear.
- We might be among the first or even the first technological civilization in the Milky Way, and life might be rare in the universe.
- The universe is now welcoming to life, and Humanity exists at a convenient spot in time, but most stars are red dwarfs that can sustain habitable planets for trillions of years.
- A civilization coming after Humanity will find it hard to have room to survive, creating a deadline for any space-faring civilization.
- Humans are curious, expansionist, and hungry for energy, and we could become a Galactic Civilization that creates noise signs detectable by telescopes.
- Loud civilizations that expand around the galaxy may prevent new civilizations from appearing, creating a short window for life to spread and thrive.
- Quiet civilizations that limit themselves to one star system are not a concern for us, but we are on the path to becoming loud.
- If we are really early, other civilizations will eventually catch up, and it only takes one loud civilization to crowd out others from the entire galaxy.
- Meeting other civilizations does not necessarily mean war or conflict, but it means that new borders will arise, limiting the fate of some civilizations forever.
- If we are early, we have an incredible opportunity to mold thousands or even millions of planets according to our vision and dreams and meet other civilizations as equals.
