I've seen many iterations of this question, though they've focused on the effects entailed.
Let's pretend the earth has been ripped in half, as if some colossal force grabbed the northern and southern hemispheres and pulled them apart without leaving any scars besides the rift between the two halves. Now, let's pretend we were able to watch this unfold from the Moon (which is unaffected by the occurrence) and pause time the instant the two halves stopped moving, but before they began collapsing into spheres (in fact, let's say there's some force preventing them from doing that).
Is there some way to get a 3D model of this, perhaps via some simulation or something? It definitely wouldn't be a clean split, so there would be some debris that would end up suspended.
In fact, now that I think about it, I feel like I've seen a movie where a planet, moon, or asteroid was destroyed due to an explosion at the core that manifested as a shockwave along one plane, effectively splitting it in half. I could probably get the info I need from those plus some guesswork.
Any insight is appreciated!
