Thank you so much for this comment. The diameter of the hole is just under an inch and a quarter. Upon closer inspection, and after scraping away a bit of the sealant with a tweezer, it seems that the pipe has a fair bit of drywall or something at the end of it blocking it off like you say. This makes me not worried I've created some sort of fire hazard or anything. I think you're right about it being subfloor and that is very impressive you could tell that from a pic. The floor in other areas of the apartment appears newer, is angled differently, and seems to sit just above the level of the floor in this room (not by much just a quarter inch)
