Maybe it is part of their navigation or propulsion system. I really have no idea but there is something doing impossible things in our sky.

I’m more inclined to accept multidimensional or time travel or both, beings. The reality of time, speed, and distance, has me doubting intergalactic Travellers flying here in little vessels.

I have no idea what these things are, either, but have seen structured craft - discs, not triangles - on two separate occasions performing moves that would crush a pilot. Maybe the black triangles are "our" reversed engineered things. I never saw one, but plenty of credible people have seen, tracked, and photographed them. (Belgian Wave from the 90's for example) Definitive proof? Nope. But absolutely a data point in a large body of testimony and evidence that, by analogy, would convict a person in a criminal court.

It's fun to speculate, but rather pointless to discuss or engage on this topic with skeptics.

Yeah, like going faster than the speed of sound without leaving a sonic boom.
