I love the idea of hanging by a thread, of complete existential and cosmic precarity. To again quote the opening of Call of Cthulhu, science will reveal "our frightful position [in reality]". I like the fact that, for Lovecraft, the answer to such terrifying revelations is mostly to draw the curtains and ideally brick up the window and insist "nothing to see here." The opening quote offers that as one solution, but it's recurrent in his stories. It's what the protagonists end up doing in the Dunwich horror mentioned in the blogpost.
