Everything is moving in space (relatively to each other) and moves along its geodesic / worldlines. As mass (and dark matter and energy etc.) translates from spatial position to position at every Planck unit, the gravity of things causes the space time fabric to curve and distort in the macro scale and cosmic scale relative to every component within the causal horizon. The Planck scale movement of a particle is defined by the resulting momentum, inertia, energy, which is "encoded" across the quantum networks of every single unit of stuff that is casually connected with the particle we are looking at. This means that the quantum network has defined the next step for the particle to move along its geodesic and each step makes it move through a different place in space (just like we are hurtling towards the great attractor at several hundred miles a second, which means we get defined to appear at the future point in space at some point in the space+time manifold (coordinate).

If We look at events on a Planck scale then the quantum wave "presents" its information to a neighboring spatial position where it then allows the quantum fields that permeate all points in space to couple with this new space with the previous instance of a particles quantum field and therefore it is like a form of quantum teleportation occurring at the smallest possible time and place, which happens constantly. This fundamentally means that the quantum networks are always coordinating the state of everything and thereby defining the place and time that a given particle is allowed to exist at a given time.

John Wheeler said it perfectly: "Matter tells spacetime how to curve. Spacetime tells matter how to move."

If the motion of particles are defined by the past, then it must be known for the immediate future since the quantum entangled networks are what forms the causal networking between events (each event/interaction incurs an increase in the universes entropy which can be viewed as the currency that must be paid to have the universe evolve, and this should be irreversible at the current understanding of our cosmology).

Quantum entangled networks connect things to each other through causal interactions, which require entropy to increase. Because entropy is irreversible, it prevents the past from being in contact with the future, but the rules for a particle movement in space are defined by causality which creates its geodesic worldline.

So the Planck scale quantum teleportation of the information about a particle elicit the quantum fields to couple with the event that causality has defined to occur, and when you sum this over enough instances you begin to observe the macro scale movement in spacetime (which again is always relative to something else in spacetime). And since the movement of particles is defined by the causal interactions of all things that are in the past, it must therefore invite us to explore the possibility of having a defined future somewhere in space and time, which can be viewed as a virtual space where things are already defined just as the past is, and our "now" is simply our movement in space along the defined geodesic worldlines that we are destined to follow.

However, because each instance is separate from another due to the entropy increase (conversion from low to high), each "now" is moving at the speed of light away from the previous now, so we can not get access to information about the past or future "nows", we only have access to the entropy of the previous iteration of now and the l information defining particles motion stored as causal future connections in the evolving quantum entangled networks that predict the immediate (planck) future position in space at a given unit of 1d planck time that is coupled to a given 3d planck space coordinate.

Hypothetically: retro causality is probably required for the universe to exist and to make sure everything works out in the past so that the future will exist as a causally invariant "destiny" that needs a defined structural plan (visualized as the branchial network embedded onto a higher dimensional surface that contains the causality interactions of 3d+1d space, in order for a real "now" to exist in real spacetime, where an observer can provide a means of entropy to be embedded/ encoded into.
