In my opinion, niblingo was a wonderful idea! It made her feel included in the family and only she can be Sheldon's and missy's niblingo not anyone else. It sounds sweet too
i mean, yeah sure, zero doesn't exist but it still does as a useful concept that helps us further our understanding of everything and to navigate this world better. kinda like time or good and bad. it's an existential paradox but that's how i understand it
What's a thing? It's an object..or something that objects to light and reflects it and let's that objected rays to fall on the sensory receptor called eyes.. if there is no thing.. it's represented as zero. If you look and your eyes sense no thing..just as tracking the eye movement that searches every where around and comes back to the same place without anything objecting light to sense ..just like the number 0 starts and ends at same point. It just says no thing exists... But it never said you don't exist. And you are no thing..
