How could it possibly be comprehensible, that time exists without the intellect that uses it? — Mww
It would not be comprehensible in that sense, as comprehension is something only done be a comprehensive entity, mind, consciousness etc.
But you will then have to assume a universe without such an entity, consisting only of moving bodies, atoms, matter/energy.
Events will still happen despite no observation of such events by entities such as minds etc.
Events A, B, C happening all at once removes temporal linearity, in succession reintroduces it.
So time only makes sense only in terms of actions/events occurring linearly.
It is of course a very complex notion to speak of time in terms of events occurring simultaneously as well as instantly as there was no present or past state for those events to occur in. It could be said that 3 such events being instantiated are unobservable yet if happening non-instantly they’re occurring in time although not linearly but also in space. Spacetime.
But isn’t that the Big Bang ? A huge explosion/expansion emitting forms of matter/energy all at once in all spatial directions! Simultaneous-Instanteous event in terms of origin, linear thence as the expansion itself takes time and grows outwards linearly at a measurable rate (probably faster than light but still measurable)
Our apparatus of detection of this event looks at the early entropy state of such an event, a snapshot of this simultaneous matter/energy emission at its earliest point from origin to the outwards expansion.
Before this event, the prior state leading to this simultaneous burst cannot be known due to multiple events such as A, B, C occurring all at once and also instantaneously in opposing directions or even criss-crossing as there is no linearity to speak of if such an event is a one off in terms of origin.
In the static void of such a universe prior to the big bang, how could events like this even occur if matter/space/time was created subsequently? The assumption in my last sentence has started to become slightly outdated in the current scientific realms of physics/astrophysics so truth on the matter remains a subject ripe for scientific/philosophical speculation or just plain old metaphysics.
