Are you serious about the math teacher comment?
Thanks, Nuke_em, for finding out more about Wicramasinghe than the so-called debunkers did. Skeptics are quick to attack the guy without bother to learn more about him and his accomplishments. "fringe scientist", just a "math teacher" , If he isn't from NASA, he suck? Come on, you can do better than this.
I usually just browse this site as I'm interested in the weird and wonderful but I felt compelled to comment on the above statement. As a mathematics undergraduate in the the early to mid 1990's I studied "Mathematical Methods III" in Cardiff University under Chandra Wickramasinghe. As a person I found him quite arrogant but that is neither here nor there. As a lecturer he wasn't the greatest and quite frequently made mistakes in his classes which some of the brighter students were more than happy to point out.
Given this, I wouldn't put too much credence in his claims as he's proven to be prone to error (in my experience anyway). Don't get me wrong; I'd love to find concrete evidence of life elsewhere in the universe but I don't have much faith where Professor Wickramasinghe's concerned unfortunately.
