Humans - Intergalactic Definition: Developer of the Black Hole Bomb, no other information needed/available at this time.
Humans develop real technologies such as Black Hole Bombs. Ya, you heard me... Black Hole Bombs!
Can you imagine being an alien and stumbling upon Earth, and just before you invade, you get a transmission from your leaders back home telling you to stand down and to observe Earth only and to watch for possible new technology and ideas...
50 or 60 years go by and you are slightly impressed with Earth's advancements, but nothing worthy of calling back home and saying they were right about... You should have invaded you keep thinking... What a waste of time...
And then you hear it.. Black Hole Bomb.... Yes commander. I said Black Hole Bomb. They literally just told us how to build a Black Hole Bomb... NO SHIT! NO JOKE!
fast forward... The universe is now armed with Black Hole Bombs and they have an armada of nanobot AI ships transforming millions of black holes throughout the universe into landmines and bombs...
GREAT JOB EARTH!!!!
And here I was, all worked up over Artificial Intelligence and Antimatter and Parallel Universes... damn...
