I suppose then you’d have been more satisfied with the example of an infinite number of grains of sand, each polished smooth and strewn across an infinite beach.
Or simply an infinite expanse of empty space, each with unique coordinates, yet unable to be differentiated in the absence of any reference.
The point being, infinity itself is a concept we defined a certain way. And no part of that definition mandates variation. People who hear “infinity” and immediately conclude that, in one universe they are a singer, and in another they are an astronaut, and in another still they weren’t born at all, etc., are making an incorrect assumption about the nature of infinity itself.
Framed another way, we have exactly one example of a possible universe. Tell me, what creative force do you believe in which would intervene to ensure other universes play out differently?
