Scientists are rather conservative > about things like this. Actually, "theory" in this context does not imply "possibly wrong". It is just a coherent explanation subject to several technical constraints that I won't bore you with. A "theory" in this sense may even be provable yet still be called a "theory". This usage is NOT the same as when someone says "it's only a theory". > You're not one of these people who believes gravity is > electromagnetic are you?

All we "know" about them so far is a bunch of theoretical speculation..
