Is this fog (x) stuff really used much when it comes to physics?

I love astronomy witch got me into physics.. I want to research and learn about the universe and space.. Not domains of functions.. Are domains even needed realistically when it comes to astrophysics? Maybe some mathematicians can help me out. When I look at formulas and equations like gravity, gen relativity. They seem so simple e=mc^2 etc.. And all the formulas look like sqrt over a fraction etc.. Simple stuff, so why do I need to learn domains and functions. ?
