Black Hole
Black Hole is one of the tabs in Galaxy Idle Clicker. It's being used to spend Black Matter for Special Upgrades and check current Black Hole Travel stats.
Upgrades unlock as you perform more Black Hole Travels. Each time you will perform a Black Hole Travel you will gain Black matter that you can use to activate one of the upgrades.

Black Hole Upgrades[edit | edit source]
Black Hole Upgrades cost Black Matter and unlock upon performing more Black Hole Travels. Here you can spend your Black Matter to purchase various powerful progression upgrades.
Upon performing Black Hole Travel prestige (Tier 2 Prestige), you can refund 1 Black Matter Upgrade. You have to do this before killing 1000 enemies, so make sure to do it in the start of the run if you plan on refunding.
Some Black Hole Upgrade costs can be decreased after performing Supernova Collapse (tier 3 Prestige).
