Interstellar
From Gardens wiki
A yard at the edge of the Sun's wind: sweep up hydrogen, make antimatter, build a starship around the drive cores, and send it to another star.
Opens: the ⊹ Heliopause site is open.
By hand: Skim hydrogen gives 1 hydrogen, free.

| ⧃ Antimatter trap | Magnetic bottles in a cold vault: antimatter must never touch a wall. Room for antimatter, hydrogen and shield foil. | 100 🝛 alloy, 10 ▱ plates, 60 ⍥ cryogen | +150 ⍉ antimatter storage, +300 ⍤ hydrogen storage, +200 ⏛ shield foil storage, uses 2W | ⍷ Antimatter capture researched | on/off |
| ⧁ Antimatter reactor | Lets a trickle of antimatter meet matter: more power than anything else, but it burns the fuel the starships need. | 100 🝛 alloy, 8 ⛭ parts, 10 ⍉ antimatter | turns 0.01 ⍉ antimatter/s into 30W, only as far as its inputs allow | 225 𓏛 knowledge and ⍷ Antimatter capture researched | on/off |
| ⏖ Deep space array | A field of dishes pointed at the nearest stars, to find worlds worth the trip and to hear the colonies call home. | 100 🝛 alloy, 8 ⛭ parts, 60 ⏛ shield foil | +1.5 ⚝ data/s, +0.5 𓏛 knowledge/s, +0.5 𓂀 insight/s, uses 4W | ⧬ Exoplanet survey researched | on/off |
Starships and colonies
Once the Starship recipe is open, a Starships list shows below the buildings: each star you can reach, with a Launch button for each cruise speed. A launch costs a ⟠ starship and antimatter: 20 at 0.5c, 60 at 0.9c, 180 at 0.99c.
Time dilation. Near the speed of light a ship's crew ages slower than home. For a star d light years away and a speed v (a share of the speed of light):
- Years at home: d / v for the trip, plus d for the news of its arrival to come back.
- Years for the crew: d / v × √(1 − v²).
A year here is a game year (20 minutes). When you launch, your garden jumps ahead by the years at home: it does that much of today's work at once, up to what its stores hold (like Skip ahead; the calendar stays). The ship then arrives after the years its crew lives, and keeps flying while you are away. A faster ship means a shorter wait and a smaller jump at home, but more antimatter.
| Star | Distance | Colony bonus | At 0.5c: crew / home | At 0.9c: crew / home | At 0.99c: crew / home |
|---|---|---|---|---|---|
| ✶ Proxima Centauri (Proxima b) | 4.2 light years | up to +20% 𓎟 crops | 7.3 years / 12.6 years | 2 years / 8.9 years | 0.6 years / 8.4 years |
| ✷ Tau Ceti (Tau Ceti e) | 12 light years | up to +20% 𓏛 knowledge | 20.8 years / 36 years | 5.8 years / 25.3 years | 1.7 years / 24.1 years |
| ✹ TRAPPIST-1 (TRAPPIST-1 e) | 40 light years | up to +10% to all production | 69.3 years / 120 years | 19.4 years / 84.4 years | 5.7 years / 80.4 years |
Colonies. When a ship arrives it founds a colony on that star's world: one per star, and there can be one at every star. Each colony is a Legends milestone, earns a laurel once ever, and gives this garden a lasting bonus. A colony arrives with the technology it left with: its bonus is the most it can give times the share of all techs you knew when its ship launched. So the fastest ship is not always the best: researching more before you launch gives a bigger colony. The Colonies list shows each one, with the techs it was founded with. The game goes on after.
Each further copy costs 15% more than the last. Selling a building gives back half of what the last one cost.
