[Baseball is Life]

I have two questions, first what are the physics involved in a ball crossing into the zone from the side- is it even possible for a pitcher to do it and, if so, do current umpires view the zone as a plain or in three dimensions- would the even call something cutting across the back of the zone a strike

Sliders sort of go side to side. And, yes, umpires at MLB level see the zone as 3D. They often call curves that drop in. All the time actually. Think of the Kershaw curve that catches the back of the zone.
