Black Hole
From Bacterial Takeover
After the player has destroyed a certain number of planets, it becomes possible to enter a Black Hole. Doing so resets most of the upgrades and resources, but earns the player Dark Matter and can unlock additional features, such as the Dark Matter Institute, where new technologies can be researched.
Black Hole Formation
It takes 25 planets for a Black Hole to finish forming the first time. This number is increased by 2 planets for each Black Hole the player has entered previously.
It becomes possible to enter when Black Hole formation has reached 100%. This percentage cannot be exceeded and will remain the same even if the player keeps destroying new planets without entering the Black Hole.
