The barologist does not study bars, nor does he think this is funny.
Some jokes are always funny, no matter how often you hear them, some are funny once, and some are tragic because they are so lame; these latter jokes are also known as Dad Jokes by some, and are best avoided.
One day, the barologist is standing there getting yelled at by his wife for something, and it dawns on him: I have slipped into an alternate universe, one where my wife is made at me for reasons unknown.
After that he devotes thought to alternate universes, and their implications.
There are alternate universes that are full-fledged universes, and there are those that are circumscribed; small eddies, looped-off instants, some only a second or two long, some a few seconds or minutes (rarely) that can be visited and revisited.
An example: the moment when the barologist and his daughter, who have been moving furniture, tilt up her heavy wardrobe, which they have moved into her living room, and the barologist is squatting there with his end of the wardrobe above his head, wondering if they will succeed in lifting it – that moment of not-knowing – will he get a hernia? Will his strength fail and it crash back down on top of him? Is he strong enough? Should they give up? Perhaps it is density that creates such looped-off alternate universes, because when the barologist thinks about it, the moment is dense with wondering, and not-knowing, and daring, and ultimately dropping all thoughts and fears and just lifting it, and the feeling of accomplishment when it stood.
The alternate universe the barologist is thinking about is about three seconds long, and he finds himself back in it now and then, squatting with a heavy wardrobe at arm’s length above his head.
Or, another one: a lady on a beach in Hawaii. The barologist is about 12, bored in front of his hotel, sitting in beach grass up the slope of a rather steep sandy beach, when a wave crashes right onto the lady and takes her white bikini, and her tan lines underneath are just as white. This is connected with two more seconds on the plane home the following day, when the boy barologist recognizes the woman, now fully dressed and on her way home too and he wonders if she recognizes him and what she is thinking if she does but she probably doesn’t.
Or, a blond woman standing naked in her upper-storey window as the barologist walks to work. Or, the barologist getting off a bus and slipping on the ice and falling on his hip and people asking if he is okay and the wind is knocked out of him and he says thanks, I’m fine, and limps offstage as fast as he can.
Or, et cetera.
The barologist wonders if it is too late to become a scientist of alternate universes.
