Experiment: Earth

The Earth Experiment

The Earth experiment is one of 12 experiments in the laboratory, available at laboratory tier 3.

The goal of the Earth Experiment is to get a certain amount of density.

Mechanic

Drills dig up earth, upgrades collect earth faster. Additional drills can be purchased. Upgrades and drills cost increase exponentially.

Compression reduces volume/diameter and raises density. Stability can be reduced depends on compression mode, if the stability depletes to 0% the experiment will be stopped and have to be reset.

The density will eventually reach a maximum, at 80 * (4/3)^3*log₃mass, which is approx. 80 * mass^{0.78557852143}. This means to get all the modules, you must have at least 2.7e7kg mass, and to complete all goals, you must have at least 8.92e12kg mass.

Compression modes

• Slow & Safe: Drills get slower the higher compression rate gets (stopped at maximum rate), slow compression but won't reduce stability.
• Quick & Dangerous: Drills can continue normally regardless the compression rate, very fast compression but drains stability
• Stabilize: Only increases stability and slows down the drills.

Prestige

Prestige resets all your drills, mass and diameter and will require you to have a certain amount of mass drilled. Every prestige multiplies the prestige goal by exactly 1.33, so the current goal mass is 1.33prestige-1 * 100kg.

You must choose between 2 bonuses:

• -20% Stability loss & +10% stability gain: Reduces the stability loss when using Quick & Dangerous compression mode and Stabilize mode will increases stability more quickly
• +30% Compressor React & +5% Drillpower: Increases the compressor reaction (the compressor will reach higher compression rate faster) and increases amount of mass drilled
