Spacetime is like a movie reel, or better a stack of pictures on top of one another. Time is just a way of labelling the individual frames or pictures, and the word \u201cmove\u201d just means to have different coordinates in space at different times ie to be at different places in different pictures. It doesn\u2019t make sense to ask for the image of something in one picture to be in a different picture.<\/p>\n
