Hi. I hope I'm posting in the right place. I was just wondering, what is the difference between the graviton and the higgs boson. I'm not quite sure, I think I sort of understand it... but not really. Also, since I don't want to make a new thread for such a small question, is there anything known about the curvature of the 11th dimension in M-theory? Is there even such a thing for a dimension so small? Does it matter?
