A team in Australia turned thought experiment into lab reality by using lasers. Their subject matter was not a photon but a helium atom. The lasers they used served as a pair of grates, one before the other, with the second grate randomly dropped in.

What they found is weirder than anything seen to date: Every time the two grates were in place, the helium atom passed through, on many paths in many forms, just like a wave. But whenever the second grate was not present, the atom invariably passed through the first grate like a particle. The fascinating part was, the second grate's very existence in the path was random. And what's more, it hadn't happened yet.

In other words, it was as if the helium particle "knew" whether there would be a second grate at the time it passed through the first.

    Exactly. God created a static but very complex universe. We are mere bugs in intellectual comparison. To us, it seems dynamic and unpredictable at the edge of our limited understanding. To Him, it is like a simple algebraic formula. He knows all the possible inputs and their corresponding outputs. The only variable in the equation is Mankind. This is how and why I believe in predetermination and free-will at the same time. He knows every possible choice we can make and the outcome of those choices. Its all been iterated in His mind...and the equation was designed to always output, sooner or later, the answer He desires. 42, maybe? Who among us can truly know? Our free-will determines the route. There are many routes but only two destinations: Renewal and Destruction.

    I think Christianity (depending on denomination) teaches that while the future is predetermined we still have free will. The way I heard it taught is that just because we have no control of our past doesn't negate the fact that we have/had free will to do what we do/did. We're still responsible for what we did. The future is simply the past of a more distant determined future. God already knows the future because he knows how we will act under all possible conditions, he knows what future conditions will come to pass, but this doesn't change the fact that it is we that voluntarily chose/choose how we wish to act under these conditions. I believe the doctrine is called divine providence.

      I think Christianity (depending on denomination) teaches that while the future is predetermined we still have free will.

      Like nearly all religious doctrine, it's full of doublespeak and riddled with cognitive dissonance designed to force a believer into accepting two sides of a contradiction at the same time and thus undermining their ability to think (or argue against the point) clearly (or sometimes at all).

      What they're really saying boils down to is:

      "Your fate is predetermined. You have absolutely no control over it, but we're going to tell you that you do, so you're consumed with guilt, and we're going blame you for everything you have no control over anyway, so you better throw yourself on our (deity's) mercy and maybe, just maybe, you won't burn in hell forever, but you probably will, because god loves you!"

      One of the classic ways to brainwash, disrupt, or otherwise attack a person's ability to reason is to try and force them to believe two contradictory things at the same time. What is interesting is, depending on the level of emotional investment, the lengths to which people will go to turn themselves into intellectual pretzels to do just that.

        And what makes you so confident that everything fits nicely and neatly into your view? This universe does seem to have its fair share of "two sides of contradiction at the same time".

        So just because you believe the "free will vs knowing the future stuff" is contradictory doesn't mean that you are right.

        The apparent results of this experiment is more data indicating that things are not all that simple. If you believe in the scientific method, you should be willing to challenge your beliefs given new data. Perhaps the experimenters made a mistake or they misinterpreted the results, so I'd wait till it's confirmed by others.

        But so far, this universe isn't so "neatly simple", thus if it really has a Creator, it would be really stupid to assume that the Creator is as simple as many of those silly philosophers/logicians like to assume[1].

        [1] A lot of what they do is as stupid as the Ghosts in Pacman assuming the Creator(s) of the Pacman game are as simple or even simpler than the game itself. And using the Pacman game logic to prove the nonexistence of a Creator of the Pacman game is even stupider.

        Arguments that the Creator if he does actually exist doesn't really care that much about those in the game, do seem a fair bit more tenable.

          That's a Deist argument, not a Christian one. I hate how Christian apologists constantly make Deist arguments and then switcheroo in ol' Yahweh when they think no one's looking. It's dishonest as hell and if there *were* a good and just God that took realtime interest in human affairs those people would burst into flames at the podium when they did it.

            uh I did already say: "Arguments that the Creator if he does actually exist doesn't really care that much about those in the game, do seem a fair bit more tenable."

            tldr; "even if a creator exists, the evidence is that he doesn't really care that much or he's an asshole" angle works better vs Christianity than the "contradiction" angle.

              I think you're on to something...

              1. Create a universe where multiple contradictions can exist.
              2. Make the inhabitants of that universe worship you or suffer divine punishment.
              3. Make them feel guilty for questioning the contradictions.
              4. Make sure that they will suffer during their life, but tell them that you love them.
              5. ???
              6. Profit!!!

          So just because you believe the "free will vs knowing the future stuff" is contradictory doesn't mean that you are right.

          If you can know the future, that means it is pre-determined, if it is pre-determined you cannot have free will to make choices. If you wish to argue otherwise you are trying to define "free will" to mean something other than what it does. It really is that simple.

          Personally I don't believe in free will, as we are in essence just incredibly complicated machines. If you believe we can have free will you must logically believe a single die can have free will over which number it will land on when you throw it. You might try to claim we are different, but other than in terms of complexity, how are we? At what point on the evolutionary tree did we acquire free will?

          Now whether the universe is deterministic or not is a different question. As although a deterministic universe prevents free will, the universe being non-deterministic doesn't mean we can or do have free will. And we don't know how the universe works well enough at a fundamental level to know whether or not the universe is deterministic.

        Spirituality has little to do with the physical world. Like quantum mechanics, it seems like paradox when viewed logically. But logic fails to convey the universal truths in the unseen. Your brain cannot even understand your brain - only a scaled down model of it. Likewise the ephemeral interconnections of all matter and energy. So - it is taught in paradoxes to the uninitiated, paradoxes that your mind cannot reconcile, like an Escher painting, until you give up on recording and analyzing your observations, and instead let the experience flow through you.

        It is the pinnacle of difficulty to impart a personal viewpoint of something that cannot be explained to another person through our crude symbolic language. But there are techniques that can lead others to enlightenment. Most of them use paradoxical lessons.

          *Some* of them.

          Oh I think we're making great strides [newscientist.com] in that direction.

          >it is taught in paradoxes to the uninitiated, paradoxes that your mind cannot reconcile

          I see no paradox here. Nor anything to reconcile. Seems rather clear cut.
