Science price and calculator
How much science each level needs:
Calculator: time and instant speed-up
Enter your science and choose a level — we'll show how long the research takes and how much dark matter is needed to finish it instantly.
Formulas verified: time = science price ÷ your science per hour (but no less than price ÷ 5), divided by research speed. Instant completion is calculated by the dark matter for the remaining time.
