The Black Hole

"Sucks in ores into a black hole that are turned into pure energy. Gives 25x the value of the ore but costs 1 Research Point for every 30 seconds the black hole is open."

Overview
The Black Hole is a Legendary-tier furnace. It's one of the two furnaces that costs research points to use, the other being the Dreamer's Fright.

Trivia

 * It is the only furnace in the game that does not have a specific "square" area for the ores to be processed.
 * It is the second Almighty-tier item that has been added. However, in the Gun/GUI update it was reconfigured to the Legendary-tier.
 * If you stand too close to the black hole, it'll kill you, so be careful when you place it or set your spawn.
 * It can be used as a (very expensive) base defense for rich people.
 * It is currently the last furnace in the shop.
 * Although no one likes to lose research points, this furnace only takes away 120 research points per hour.
 * It is the most powerful buyable furnace in the shop, excluding cell furnaces.
 * Ores launched into the Black Hole by an Ore Cannon doesn't actually process the ore, although it says it "submits ore into a Black Hole".
