the previous solutions have all been extremely stupid. they are actually not parallel worlds. different dimensions could be like ours yet in accordance to 3 variations of string concept and different greater effective-dimensional theories, they’d no longer be detectable to us consistent with how this theory stated as “the majority” would artwork. Theres different theories that say the size are so small that we are going to no longer see them and that they are bunched up sub-atomic “balls”. this is an amazingly complicated factor to truly visualize or maybe think of of conceptually. this is as stressful because it sort of feels.
