Axil: if your post gets discussion it will not be worth more.
By reading headlines and not understanding the physics you are generalising a specific property of bottom quarks - vs only left-handed ones can decay into top quarks - to a completely different and much broader proposition about decay of radioactive nuclei. The quark bar is predicted by Standard model physics, and there is no such simple bar to nuclei decay.
I don't see why this post was censored to this obscure thread. THHuxleynew always authors singular posts that a cogent and informative. Why would such quality work be moved into this warren obscurity? Could it be just the appearance of my moniker prompts such an action? THHuxleynew, I would advise you to avoid commenting on anything that is connected to me. It is not good for your reputation and standing around this site.
