so are all events instantaneous? If so, then how can events of different time lengths be compared? If not, then what do we call an interval between different points in an event?

[Anonymous No.15122585]

A measurable unit separating events.

Time exists in order that everything doesn’t happen all at once, and space exists so that it doesn’t all happen to you. -- Ray Cummings

[Anonymous No.15122599]

Time in its most basic form is a result a universe being causal. If each event is caused by a preceding event, that linear sequence is time itself.

The idea of "right now" or "the flow of time" is an illusion of consciousness and only exists to aid in your survival as a biological entity.

>define time
The appropriate definition depends on the context. There is no need to rigorously define it outside of a specific context and no point in trying to.

[Anonymous No.15122905]

Time is the advancement of entropy within a system.

>>15123030
how can the different points of an event be timed in accordance to each other if you can't measure the distance between the beginning of one even and the end of another?

define event without recurring to time and you win

Hush, subhuman. There's nothing illusory about the sensation of gradual change. Your "causality", on the other hand, is a simplistic monke brain model that has nothing to do with objectivity.

[Anonymous No.15123190]

Measure of happenings. If something happens, time advances. The problem is to find happenings to measure even intervals of time. Probably not possible and the vague and patchful theory of relativy proofs it.

[Anonymous No.15123193]

>>15123190
Time is just the rate of happenings per happening. :^)

[Anonymous No.15123235]

>>15123177
I'm not even the anon who posted it, it's just funny how you misread the point. It appears you tried again and still got it wrong, because he neither said that conscioussness nor that the sensation of change is illusory.
Anyway, if causality is bs how does this non-illusory sensation of gradual change come about, and what changes and why? Objective answer please

[Anonymous No.15123260]

>>15122546
Our time cycle is based on the measurement of our sun, some planets have multiple suns so their days are are longer than ours. The time cycle of a planet is based on the distance of its star or sun(s).

It's a conceptual framework in order to understand things. It isn't a thing in-of itself.

[Anonymous No.15124594]

>>15122546
Light enters your retina, your optic nerve signals electrical impulses to neurons, you perceive each moment as a short 'snapshot' depending on your reaction time (normal is 250-300ms) Each moment passes by, comparable to a 'snapshot' or 'picture' (as if it were a camera) and thus the important moments are stored and encoded into long term memory. Depending on your CNS responses and the situation you find yourself in, you may also experience time dilation or distortion. In a life or death situation, time dilation often occurs, your time perception would likely slow down massively to warn you of danger. You could compare time as measure of change, and measure of change as entropy. Compare entropy to chaos, or an increase in chaotic signaling across the brain (speaking from the brain as a computer metaphor)

Overall this is how we perceive time. It is an embodied process and from a non-linear point of view, zoomed out, you may even notice how your decisions played a part in reaching the present. Counterfactuals I'm not very familiar with however, this is pretty much it. Correct me if I'm wrong
Also, cognitive biases developed along with heuristics like rosy retrospection to optimize present decisions. And prevent rumination about all of this

[Anonymous No.15124604]

And keep in mind, moments are strictly estimations. They are relative to the observer. Time is not global, it is a biological process

It is also dependent on your circadian rhythms and dopamine signaling. This is why dopamine or circadian-rhythm disordered patients, like Parkinson's or Alzheimers perceive time differently. Parkinson's is a movement disorder and time intervals are underestimated IIRC
