Hey, there, sorry! I was really kidding about the "thread killer" thingy. It's great that you made several last posts in the science subforums. When people don't reply, it could be that the discussion is finish (problem is solved), or nobody has new argument yet. Unlike in non-science subforums (like Free Thought), making post in science subforums is rather more difficult, because we have to have enough knowledge. So, no worries! =)
