One day Merle had seen the astonishing truth of the case, though admittedly he had been most of the night working his way from one Whiskey Hill saloon to the next, drinking.

"Merle had seen the astonishing truth of the case"
This makes it sound like Pynchon's going to explain exactly the connection Merle saw between Blinky Morgan and the Michelson-Morley experiment. Nobody would blame you for rubbing your hands together, pulling your pants down to your upper thighs, pumping the lotion bottle three or four times, and getting ready for the money shot reveal. And while I, sitting here with my pants half off, don't know for sure if there's going to be a reveal because I'm reading this long ass book one sentence at a time (probably due to some early childhood brain injury), I'm hesitant to start pumping lotion into my hand because I quickly noticed the conjunction "though" which is how a grammarian shouts, "Before you begin fondling your nether regions in anticipation of universal truth revealed and/or boobies, take a second to regard the framework of the first clause by studying this second clause!"
"though admittedly he had been most of the night working his way from one Whiskey Hill saloon to the next, drinking"
See? Merle was drunk when he had this revelation so take it with several grains of salt on the rim of your tequila shot. Do teetotalers understand how truly overwhelming revelation can be when one is in an altered state? I feel like the reaction to revelation while you're sober reduces itself to a nod of the head as it's swiftly incorporated into your understanding of life and the universe around you. In an altered state, revelation becomes truly religious. The immenseness of the revelation multiplies by the grandeur of the altered state. A drunk might be, as Merle here, astonished, a pothead flabbergasted, while somebody on mushrooms or LSD might trepan themselves to let out the massive truth flow freely from their blown mind. I may not have trepanned myself but I regularly had mind blowing revelations about severely mundane things while on mushrooms or LSD which thought about later sober just made me shake my head and laugh. I'm glad I never started a cult about how the number three connects everything and triangles are the perfect shape, or how some VCRs' pause button would pause the show but then to unpause the show, you'd have to press it again instead of play. Even though, you know, the button's purpose was to PAUSE, not to UNPAUSE!
"Whiskey Hill"
Whenever I research Cleveland to read about Whiskey Hill, I just get modern mentions of Whiskey Island. I'm assuming this is the same place but things have changed due to climate change!
