Well, since paradoxes are at hand, let us see how it might be demonstrated that in a finite continuous extension it is not impossible for infinitely many voids to be found.
What has philosophy got to do with measuring anything? It’s the mathematicians you have to trust, and they measure the skies like we measure a field.
