This is an ancient problem, which is the deformation of Achilles paradox, one of the three paradoxes of the ancient Greek philosopher Zhi Nuo.

The fundamental problem of this problem is: how to pass through infinite points in a limited time.

Answer:

1, infinite points form a line with length, and the problem can be solved through a limited distance in a limited time.

2. Since the limited distance can be divided into infinite points, the limited time can also be divided into infinite time points, and the infinite time points can solve problems through infinite space points.

3. Even after infinite division, its total distance (integral) is a small fixed value, and the time obtained by dividing this fixed value by speed is also a normal and not too big value. Problem solved.

According to quantum theory, space can't be divided indefinitely, so the problem doesn't hold, and the problem is solved.
