i tried reading about this stuff but im not exactly the sharpest knife in the drawer. how can worm holes be possible? i’ve read the “folded sheet of paper” explanation, but how can you fold space? its not flat like a piece of paper! and what are paralell universes? how could you travel through time by travelling faster than light? how is that possible? which direction would you have to travel to go to the past? will someone please break this down to the D- level for me?
