[[Scientists]] are different from most resources, as they are returned to the player after each use and are never lost. The only way to lose a Scientist is by resetting the research tree of the [[Dark Matter Institute]] (if the [[Doppelganger]] technology has been purchased).

The player starts the game with one Scientist. New Scientists can be bought for [[Diamonds ]] and one additional Scientist can be earned by researching the '''[[Doppelganger]]''' technology in the [[Black Hole#Dark Matter Institute| '''Dark Matter Institute''']]. There is no limit to how many Scientists a player can have, but each consecutive purchase of a Scientist increases its price.
