Dear Tejinder,
It doesn't often happen that experts agree with me on that the current border between past and future is the only fixed point, because their view is based on Hilbert's, Einstein's, and other's block universe.
When Einstein denied the objective differences between past, present, and future, I see him definitely at least incorrect in so far, as the present "state" is no state at all because it has in contrast to past and future no extension. Therefore "living at this border" refers to something fuzzy like "today" that may include a part of the past and a part of the future.
If you have time enough, you might sooner or later read my 9th essay and find some hurting arguments that are too fundamental to mathematics and physics as to be easily swallowed.
Best regards,
Eckard
