And what pray tell do you know about length of time itself. and what And how big is an interval? The tick tock of a clock is a purely arbitrary and artificial measurement. Moreover, the duration of tick tocks is relative to speed, no? Yes, you are counting a manmade arbitrary length of "duration" of a chronology after it has begun, i.e. it's in the past. Future time is immeasurable, because it has not yet emerged. It is a latent potential, until it is associated with change. There is no such thing as independent time. It is always associated with duration of a physical process or duration of existence, at which time becomes measurable. Is it not curious that your "present" has already happened in the past? Your present experience of sunlight is already 8 minutes (480 tick stocks) in the past.
