“Since the explosion in Nicaragua occurred a full 13 hours before the close passage of asteroid 2014 RC, these two events are unrelated.”

Perhaps I am exposing my ignorance when I say that his reasoning is not, to me, self-evident. I would tend to think the opposite, that more than one rock was traveling in the same trajectory as 2014 RC and that they are related. Maybe rocks travel in clusters.

I would say rocks can travel in clusters.
