The physics of causation requires that all changes are sequential, and even when symmetrically reversible, must reverse in sequence. The prospective future, for example, if it could somehow, in some cockeyed causative directional theory, circle back to the present, it could only do so in what had by then become that future. The future only exists in our anticipation, not in physical reality.
All causes and effects are merely sequences of change. There is no actual present that's not both our past and future at virtually the same time. There is no absolute stillness in nature, quantum entanglement, etc., or notNo strategies without sequentiality either.
Without sequence, no experiments could be fashioned at all, nothing could be built to last a second, nothing would be predictable, and there would be no mathematics that these very somewhat delusional physicists need as their primary assessment and predictive tool.
Now if you want to argue that since our scientific logic is at best probabilistic, we can't say that anything is true to a certainty, then I'd have to agree. But to then ascribe a reliable degree of certainty to our most extreme examples of improbability requires a most unreliable stretch by any of our forms of logic.
Added 5-15: Causation goes in all directions and (I'd argue) has to have been essentially indeterminate for the universe to evolve in any logical sense at all. But it's not my purpose to make that my argument. All of the things that move in all of those directions do so in an irreversible sequence of change.. They can change directions and change their very substance, but cannot change the sequence in which all of this occurs.
The argument for this seems similar to the one for determinism, but is radically different. Sequences don't determine choices, and determinism is all about the decreasing, if not entirely absent, effectiveness of choice.
And as to precognition, no, it does not count that somebody was able to accurately predict what they think was the result of having seen it in what we imagine is the future. And no precognition experiments have proven otherwise.
Added 1-15-14: Both change and sequence are other than linear.
Causation comes in all directions, as must their resultant series of sequential dimensions. But to the observer, sequence is as directionally observable as its observational capability will allow. And it’s always in the “now” direction.
