Spatio-temporal bending is to point to: The speed of time, dimensional length was changed. Material is different the means of distributinging motion, can bring the distinct change of length of time speed, space.
To a heavenly body: The change of time speed is: Stand by a heavenly body more, what time goes is slower (detailed sees a picture 2 graphs 3) ; The change of dimensional length is: The true length between two positions, longer than doing not have what when the heavenly body exists, change; Stand by a heavenly body more, grow what true length changes more (detailed sees a picture 1) .
Speed of time of the aerial when 4 dimension, the change that this plants dimensional length, if put 10 dimension spatio-temporal in the picture comes out, this 4 dimension are spatio-temporal can be bent appearance. But the space that our visual system cannot present more than 3 dimension. So we cannot be watched continuously with naked eye go out to bend spatio-temporally.
The hope can solve your doubt, if still have doubt, the welcome leaves a message comment, lotus root is plain cave advocate, thank.
