Humanity began to manufacture black hole reactors.
But just like the antimatter reactors, they were enormous at first, and the prototype of the black hole reactor was even larger.
The previous experimental ultra-curvature horizon sphere, constructed solely for testing a single electron, merely amounted to a horizon-region of thirty kilometers in diameter. Now the first black hole reactor being built was a three-dimensional sphere with a diameter of one hundred and twenty kilometers. It would be constructed in a reserved space aboard the Blue Star, and while the Blue Star was massive, the reserved space could at most accommodate the construction of four black hole reactors.
However, to everyone's delight, a single black hole reactor could produce energy three hundred times greater than that of an antimatter reactor of the same volume!
What did this mean!?
