It’s a portal the shape is wrong and black holes don’t make noise also if you were that close and I was a black hole the ship would be ripped to bits instantly the bigger a mass the fast it’s dragged in
Let them come. Let the effete alien squids come and shatter against our ramparts. I name them cowards and degenerates, hiding being their shields and cloaking technology. They are no match for human steel and for honest human hatred. FOR THE EMP... I mean, FOR DEMOCRACY!!!
