Well yeah, we’re finite beings so the things “like us” tend to be finite as well — what we study in physics. A real number is what happens when you reach the end of an infinitely long light ray — the sum of such a journey. We don’t experience things like that. Yet things like spinors seem to accurately model particle physics, hinting that there’s more to the story.
