TED Conversations should be social-oriented
Many TED conversations are pure science question. I don't think TED is the appropriate platform to answer/debate this type of question. A forum about physics is right place to put these questions, e.g. http://www.physicsforums.com/
Simple reason: no one with such knowledge will join these conversations or join with seriousness. Not worth it since among noisy and irrelevant opinions, very few people with such narrow expertise to discuss about the subject.
TED Conversations should be social-oriented. If you want to hear people's opinions, you will get it here.
