Most authors will sacrifice some amount of "realism" in the interests of story-telling (compared to Yudkowsy with HPMOR at least). A couple of Magic examples come to mind: * Brandon Sanderson does a lot of Magic impacting Physics. The magic is often proper unexplained magic - but it's impact on Physics is pretty well modeled. In the most recent Mistborn book - there's a remark that explains that when the character magically reduces their weight while flying through the air - their velocity increases. I think Brandon points to that - but says that he loves the consequences at that level - getting to the point of red-shift/blue-shift for bubbles of fast/slow time is story breaking. See also his laws of magic: https://www.brandonsanderson.com/sandersons-first-law/ https://www.brandonsanderson.com/sandersons-first-law/ * Pat Rothfuss in the Kingkiller chronicles has a magic called "Sympathy" where rule 3 is "The law of conservation".
