I agree! I think they're right: Aliens are the answer. Seriously
   though - this physics knowledge that seems to spout out of these
   boys' mouths really is astounding because so much of it is so
   accurate - I'm a physics buff and I think to myself, Sci-FI
   shows need to hire these kids as technical consultants - they'll
   get the details right enough for a good story to be told. Who
   know - maybe the cartoons are giving them good knowledge (and if
   so - kudos to the writers!) - or its some kind of intuitive
   picking things up. I bet if you talk religion or life/death
   you'll get some fasctinating answers too. "
