One of my professors from my graduate school days recently posted an article about the negative stigma around seriously discussing UFOs as an academic. He previously worked at NASA and believes there are too many unanswered questions to just shrug and mumble "weather balloons". Personally, I'm a bit agnostic on the subject myself. However, I thought his article was well thought out and well written and he raises some interesting points. I figured I'd pass it along:
