We kinda know what happens if you get sucked into a black hole because of math (spaghettification, what outside observers would see, etc); can the same be said about worm holes? Would you even notice if you passed through one? What would they look like? What would someone watching someone else go through a wormhole look like?
Spaghettification is completely independent of relativistic effects; it just has to do with the gravitational gradient near a very massive body. An object near a massive body experiences more gravity on its “near end” than its “far end” which causes a stretching force. This does mean that spaghettification would be noticeable, and likely very uncomfortable as you’re ripped apart by extreme forces.
