Hi Patrick, Welcome to the list! When I was a student a friend told me about transfinite induction. While ordinary induction allows you to generalize from n to n + 1 and thus to a countable set, transfinite induction enables you to explore the continuum. He didn't explain how it was done,

Hi Stathis, I think that your example below was helpful to clarify the disagreement. You say that randomly sampling from all the files is not 'how real life works'. However, if you did randomly sample from all the files the result would not be different from the selective time ordered sampling

Hi Stephen, My point is that time as a pointer that points to what exists and what not (anymore or yet), cannot exist. You can indeed map the set of all such pointers to the real line. I agree that relativity is inconsistent with such an idea of time. Saibal Hi Saibal Are you defining
