No, because nothing is actually crossing the surface of the moon - the dot isn't an actual object, it is just a series of photons in the laser beam hitting the surface.

The lining structure of the Yellow River crossing tunnel is analyzed, the results of the beam and non linear spring model are compared with those of other models.

The practical construction results show that the computation theory of this rails beam is credible and this rails beam is a good method to enhance rail's span in the crossing site.
