However, I wouldn't advise you to run at a wall to see if you can pass through it, and I doubt that what you're doing now is being decided by your future self already acting tomorrow.

there has been many interesting concepts portrayed in films about this, theories almost endless. In any case imo that event would not be a random act by nature but be a controlled event by an outside observer obviously. However would it alter our time line or create a new timeline hence the multiple string theory. I believe in the uncertainty principle.

I like the 2002 Article from Discover better

The Discover article goes into delayed choice experiments, but the idea of adding the second opening After the atom passed thru the first is pretty good

I read another article a few years back about backward causality, another interesting read about future events determining past behavior

I would agree with future determining the past. Look at it this way. You, want to be a doctor in the future. So you enroll in college, go to medical school, do your residency, and after 11-15 years (surgeons have 7 year residency) your become one.

You wanting to be something in the future determines your past, present decisions.

Someone gets killed in the future, you would have to follow a specific path in the past and present to be in the same place and time in the future to get killed.

Like I want to eat dinner in 5 hours, I would of have had to bought groceries a couple of days ago and then within an hour or two start cooking so I can eat dinner in the future. I think all events are determined in the future in a way.

But what if the future is undefined? Then it's like dividing by zero.

It is undefined to us... But in reality it is because you want some future goal and you use the past + present to reach it.

time is not linear

Never go full retard

Well done sir.
