(E) "incomprehensible realities"
The planetarium show's depictions of celestial "realities" imply a world so vast that the narrator finds its enormity to be "incomprehensible" and terrifyingly daunting. The other options are wrong.
The answer is not (A). There is no evidence to imply that the information offered at the planetarium is overblown, despite the fact that facts indicating the size of the cosmos may appear "exaggerated." (B) is the wrong answer.
Events that are "unforeseen" or "unexpected" are not the main emphasis of the presentation. The answer is not (C). No single historical or contemporary monster is discussed in the lecture. The answer is not (D). The narrator never specifically mentions "controversial discussions" in this line.
