Of all the burning questions that might consume one’s days and sleepless nights, there is one that has followed me throughout my life and travels, across the globe. And this one appears as inscrutable as the question of how to incorporate gravity into the Standard Model of sub-atomic physics. As many other perplexing phenomena in our daily reality, this one presents itself as deceptively simple. Please examine the photograph below.
This is a marble strip separating the hallway from the hotel room at the room’s entrance. I have seen this marble threshold in many different hotels, in different cities and countries. I’ve seen it in very inexpensive hotels where the flooring is otherwise linoleum. It can also appear at the doorway into the bathroom, either in addition to the front door or instead.
I have postulated that the bathroom door presence provides a small barrier to water from the bathroom floor seeping into the bedroom area. But that doesn’t explain the marble threshold at the room’s entrance. The marble threshold doesn’t appear in other buildings or private residences that I’ve visited, such as condominiums, office buildings, public structures, apartments and homes.
I have resisted asking ChatGPT. I don’t know why I’m hesitant to go to the obvious solution for solving this mystery. Maybe I value human knowledge more highly because I know how difficult it is for people to acquire knowledge and skill, taking years to develop for the most challenging areas of human learning. A “large language model” didn’t sweat over exams, repeat practices endlessly and sacrifice sleep to advance in their chosen field of endeavor.
So if any of you have personal knowledge, gained through effort and dedication, about this mystery, I would love to hear from you.
