How is it possible to say with any certainty that the universe was the size of an apple? That analogy also implies that space wraps around, which no experiment

How is it possible to say with any certainty that the universe was the size of an apple?
That analogy also implies that space wraps around, which no experiment has ever shown to be true. This contradiction is why I have trouble.
It’s a good analogy otherwise, but the details are the interesting part.

Haven't read the paper but one likely could tell from the density. > That analogy also implies that space wraps around, which no experiment has ever shown to be true. It's an analogy meant to highlight one particular aspect, not be a perfect model of spacetime. In mathematics, there is no shortage of topological objects that are infinite but not closed otherwise.
