超470万公里/小时，这是圣诞老人的速度

据《BBC知识国际中文版》报道，圣诞老人的行动时速需达4705882公里，才能遍访全世界所有孩子，让他们早上一睁眼就看到礼物。

美国普渡大学的物理学家阿诺？彭博斯说，圣诞老人总共得旅行1.6亿公里，才能走遍全世界3×10的13次方平方米土地上的8亿户人家，探视全球20亿个孩子，这段行程比地球到太阳的距离还要远。

圣诞老人从晚上8点忙到次日上午6点，约有10个小时来分送礼物。幸好这些小孩广泛分布在不同时区，所以圣诞老人多了24个小时送东西。

即便如此，要在34个小时内走完这段距离，依然很有得拼：换算下来，时速得达4705882公里，虽远低于光速，依然快得可以产生极强大的空气阻力，足够把圣诞老人连同他要送给孩子们的礼物一并气化。不过倘若他驾的是魔法雪橇，那又另当别论了。
