So from the perspective of the pizza slice, it travels thru time and creates new timelines on the way, allowing even for different reactions from the people, for example once it’s mouldy, they won’t want it anymore and it stays in one timeline where it will rot eventually.

But: how did it start? I tried to avoid that question but making it timeless with no beginning and end, and no change to it what so ever, which comes with problems on their own. But giving it time, you also have to give it a start. I’m even fine with no end but you need a start. How hot was it in the first iteration?
