Ropporu: Imagine this piece of paper is outer space.
Nobita: Ok...
Ropporu: [illustrates two dots, marked "A" and "B" on the paper's sides] If you want to go from point A to point B the fastest, what should you do?
Nobita: That's easy. You just need to make a line from A to B. [draws a line on the paper]
Ropporu: Wrong. There's a faster way. [rolls paper into cylindrical tube that overlaps A and B] By connecting the corner of both papers, A can go through B in no time. That's what a "warp" means. You understand now?
Nobita: I... dunno. If the universe is made of paper, wouldn't it be huge and costly?
