## Axioms (5)

If thing is an instance of physical, then "the time of existence of thing" meets "after "the time of existence of thing"".
```(=>
(instance ?THING Physical)
(meetsTemporally
(WhenFn ?THING)
(FutureFn
(WhenFn ?THING))))```

If process is an instance of physical, then "after "the time of existence of process"" is equal to "interval between "the end of "the time of existence of process"" and positive infinity".
```(=>
(instance ?PROCESS Physical)
(equal
(FutureFn
(WhenFn ?PROCESS))
(TimeIntervalFn
(EndFn
(WhenFn ?PROCESS))
PositiveInfinity)))```

If thing is an instance of physical, then "immediately after "the time of existence of thing"" starts "after "the time of existence of thing"".
```(=>
(instance ?THING Physical)
(starts
(ImmediateFutureFn
(WhenFn ?THING))
(FutureFn
(WhenFn ?THING))))```

If death is an instance of death and agent experiences death, then dead is an attribute of agent after "the time of existence of death".
```(=>
(and
(instance ?DEATH Death)
(experiencer ?DEATH ?AGENT))
(holdsDuring
(FutureFn
(WhenFn ?DEATH))

If kill is an instance of killing and patient is a patient of kill, then living is an attribute of patient immediately before "the time of existence of kill" and dead is an attribute of patient after "the time of existence of kill".
```(=>
(and
(instance ?KILL Killing)
(patient ?KILL ?PATIENT))
(and
(holdsDuring
(ImmediatePastFn
(WhenFn ?KILL))
(attribute ?PATIENT Living))
(holdsDuring
(FutureFn
(WhenFn ?KILL))
