## Main Question or Discussion Point

I'm only going to be a junior next year in high school so bear with me but I've been "studying" quantum mechanics and quantum field theory for a while now. I understand most of what I've read very well but there are a few things that have been bothering me.

*How does QFT explain how two opposites attract?

*Does the idea of photon exchange between electrons on the microscopic scale also apply to macroscopic magnets?

*How does a low-energy microwave photon pass through walls and such but higher-energy visible light photons can't?

*Is there any experimental evidence for the photon exchange described by quantum field theory?

*Why does the observer matter so much when trying to apply QM to the entire universe? I don't understand this because the laws of physics are constant everywhere. If I perform an experiment where I live and travel 100 million miles out into space and do the same thing, I'm going to get the same result.

*I'm reading a book right now that basically said everyone's idea of quantum mechanics is different (other than the math). Does this mean all I know is just someone's opinion and is probably wrong?

I obviously don't have the luxury of math that you guys have so I would appreciate it if you tried to answer my questions as best you could without it. Thanks.
