If general relativity, space and time are postulated as a 4D non euclidean space that exist absolutely. All past, present, and future events are static moments in this model. In this model, the present moment can access and has knowledge of past events, but cannot access or have knowledge of future events (at least not in my experience). It is also stated that other observers can have access to events in my future that I myself do not have access to. My access to events in the past is not constrained in any way.. but it is bounded by the limit of the speed of causality into the past. Some events in the past are simply too massively far away and have been pushed even farther away by the inflation of space itself. I find this model has a HUGE ('uge if you are donald trump) burden of credibility as it cannot even begin to explain why visibility into the space 'SpaceTime', is uni-directional. If it postulates that events are visible in my future to other observers yet those events are not visible to me, when I can see so many events into the past yet cannot see into my future, even if others can. Hmmm..... no idea how to think about this.
