causality is tricky to determine.
but entropy is not
it is because of entropy that we know the time is real
although clock time where everything is supposedly evenly timed apart is a convenient myth
It’s useful myth because we need to measure clock time especially in science and engineering.
in particular you have euler’s number.
its rate of growth, rate of decay.
even though rate is a myth, because clock time is a myth, growth:decay functions work. so how is there RATE ?
