If the past is just memories & the future is yet to happen, the only time you can be certain exists is the present, and the only place you can be certain exists is the place you observe. Even though it seems unlikely, there is no certainty that I was even here typing the start of this post, about 20 seconds ago. There is room for the possibility you are shifting through consciousness in other words, you are only you for a split momment of time and you observe the memories of you then leave you, although it sounds crazy, there is no way to disprove it. You cannot travel through time thus you cannot prove the past even happened, although I do believe the past did happen, I just think its interesting to see how much uncertainty there is in the most basic common concepts.

If I could be sure you even existed, I would ask what all this has to do with quantum theory. But since you are probably only a figment of my hallucination, this is moved to speculations.

"I just think its interesting to see how much uncertainty there is in the most basic common concepts. "

So did Descartes, but he wondered about it a long time ago (1637 assuming you believe in time).

Have you anything to add?
