Common sense could be totally wrong and it is often flawed but you have to start somewhere and the best place to do that is with what does and does not make sense to you. Am I correct when I say that quantum theory says that an object exists in many places at once untill we observe it? What if there is more than one observer? If both observers observe the object at the exact same time which observer does it obey?

How can matter and energy pop into existance out of absolute nothing? How can you get something from nothing? Is there a theory or equation that shows that this is possible?

I think I'll stop here ... it seems to me that you have built far, far too many of your own, personal demands of the universe (which is under no obligation to conform to your common sense).

It has everything to do with the universe. These are some of the biggest questions facing mankind. Did the universe always exist or did it have a beginning? It is all tied together. You can not hope to understand anything without asking questions. I have not built any demands. I am using what I know of the universe and trying to figure out how can this be? As far as we know the universe has to obey it's own laws that came into existance with the creation of the universe, if the universe was created and did not always exist.
Also quantum theory does not seem to apply its rules to the general theory of relativity. As far as I know we are looking for a way to merge the theories and have a unified theory. Which may or may not be possible. How do we know that different theories can be combined into one? Maybe they can not. Maybe they obey different laws? Maybe they do not. I don't think we have enough information to say one way or the other. But I don't think it is possible to pull something out of absolute nothing
