Quote:It would take beings on order of Q and Imps to bypass those laws?
Thankfully, neither of those exist in the Doctor Who universe.
My thoughts on it are: No, even they couldn't.
Quarks, for example, are subatomic particles that exist within atoms. If you change what quarks can do, you change how atoms behave. And if you change how atoms behave, you change how collections of atoms - matter - behaves. So change quarks, and you'd probably find yourself in a universe with radically different kinds of matter, or maybe no matter at all.
Guess that is why someone like Dr mahatten is so dangerous, as he seems to want to affect all of these changes just to observe what happens!
