Nice example. Wouldn't there be easily measurable evidence of this? Imagine a flattened caterpillar like creature living on such a straw. Unwittingly, one day it might wrap itself round the straw many times. Looking back, seeing itself turned round the straw in this way, wouldn't it see slices of itself rather than a whole?

In the caterpillar's universe, light rays wrap around the surface of the straw too, so they won't see anything "missing".

Awww, of course.
