gaaranteed replied to your post:okay so the 4th dimension pic i believe they are just illustrating the time dimension (the box exists in some time t designated by the red lines) and i think the 5th dimension one is illustrating 2 different time dimensions kind of like alternate universes? i don’t know how accurate the fifth dimension one is tho, i’ve never seen multiple timelines explained as 2 time dimensions
well if u look at the black and red lines you’ll see they both only exist in a single direction, so it’s like the 4th dimension one, except after each time segment, u can go either the black or red time direction (SORRY this stuff gets me excited)
hmm ok, i think its just that this visual is too abstract for me to really get it. also i havent had a real physics class in my life.
