The theory has been tested billions of times each time a GPS signal is corrected by the differences in the clocks on Earth and the satellite clocks away from the mass of the Earth.

At any rate if one adopts a field theory of time, the differences in time are usually small. Now for a 'what if', suppose time can get twisted like an electrodynamic field that crosses itself. For a brief moment, larger time discrepancies can occur. It won't be enough to talk to Al but it may be enough for consciousness to get a glimpse. My bets are on predictive talents to be mostly dependent on other factors like deduction. But once in a blue moon...

If I had not experienced 3 impossible things according to physics I probably would have not looked deeper into conventional thinking and looked for other explanations over the last 40 years.

As for past present and future being an illusion it doesn't matter. The distance and speeds required to bring events 200 years out of simultaneous order are too great for us to achieve.
