The Seriality of Eventuality

Does causality always moves forward linearly ?

It seems like our current scientific paradigm implies, afaik, a potential infinite (spatial) expansion of our Universe, but in other moments in the History of Science, a cyclical Expansion-Contraction quality of Physical Space has been derived from the Relativistic framework; so it would seem that our interpretation of this characteristic of the physical reality can be subjected to change at any given time.

Is the future of a particle that is about to be subjected to the Hawking Radiation effect, modified in the moment of its creation… or does its future changes just when the Event Horizon is reached by it’s antiparticle ?

So far, independently of our volumetric calculations, it would seem (at least to me), that the “unidirectionality of time” is the factor that seems to offer the most reliability in the understanding of events, objects, and the relations that seems to emerge from the “unavoidable sequentiality of causality”, the apparent “irreversibility of time” and the consequential “seriality of eventuality”.

But, are there some sequences of events just pure formalities, does causality always moves forward linearly in the arrow of time ?

Is the future of a particle, that is about to be subjected to the Hawking Radiation effect, modified in the moment of its creation…

Or does its future changes just when the Event Horizon is reached by its antiparticle ?

Precisely when is the information of mutual influence of these 2 systems exchanged ?
