“Dark lightning” has apparently been known since 1994. However, I had not heard of it until recently. Here is what NASA said about it in 2013:
Researchers studying thunderstorms have made a surprising discovery: The lightning we see with our eyes has a dark competitor that discharges storm clouds and flings antimatter into space.
Storm clouds are sometimes producing anti-matter? Wow!
I wonder if this is part of the new electric drive being tested for outer space travel? I was puzzled as to where that drive would get the particulate matter to charge. This would solve that problem.
It would also account for much of the UFO sighting. As testing would be the need to be kept secret. And extra-terrestrials would be the best way to explain it away?
Good psych-ops!
