Since there must be a domain for time, and every domain we can estimate its cardinality.

Are we having a countable many of time or an uncountable many of time?

Sorry for confusing two different concepts set cardinality and time together.

    Does this answer your question? Is time continuous or discrete? – Sandejo Feb 22 '21 at 23:01
  • I did run into that question first, but I don't think it would cover my question, as continuous or discrete is a very rough estimate of set property which would depend on the topology. While cardinality is the property of the domain itself. – yupbank Feb 22 '21 at 23:03

    That's true, but the answer to the linked question explains that we don't know about continuity vs discreteness, which implies that we also don't the cardinality. – Sandejo Feb 22 '21 at 23:06
  • interesting... then there must be some previous attempt at understanding them? – yupbank Feb 22 '21 at 23:09

    We have no experimental evidence that time is not continuous, like the real numbers. In all widely accepted theories, a temporal coordinate is a real number. – G. Smith Feb 22 '21 at 23:23
