It is well known that when a person goes to sleep, there are instances when we do not experience time which has phenomenological implications. There is a temporal discontinuity. It is also known that psychoactive substances often slow down time, making the passage of 5 minutes feel like 10 minutes. We also know that any interval can be segmented into infinitely many sub-intervals according to the various definitions of the real numbers.
Considering the above facts, what is the relevant philosophy about refuting the (physical) possibility that the last 10 nano-seconds of our life may be dilated to a potentially infinitely lengthy span of perceived time? In other words, are the arguments of Zeno of Elea and his paradoxes the best logical basis for argumentation about the intersection of experience and the division of time? Has such an argument already been made?
