    It's very interesting because it shows that everything in the universe behaves both as a particle and a wave at the same time.
    It also explains a lot of the questions you posed with regards to the fine tuning of the universe.

    I was reminded of it as I was watching a spy movie the other night.

    Once we have quantum computers on a large scale and fine tuned the equations, humankind will take the biggest leap forward in it's history.
    I can't wait to see what this will bring us and where this will lead us.

    Hopefully we can construct a working Alcubierre drive so we can properly explore the universe.

    Quantum uncertainty is one of those secret rooms built into creation, and the scientists who have tried to learn all the secrets of the King’s palace have been confounded by it. David Snoke, a University of Pittsburgh physicist, says that “given our present theories of quantum mechanics, some things are absolutely unpredictable to us … hidden behind a veil we can’t look behind.”

    Snoke is thinking about a theory called observer effect. On a quantum level, the very act of measuring a system changes the system. We cannot push Snoke’s veil aside, no matter how quick or careful we are, without changing what is going on.

    Even apart from observer effect, uncertainty is inherent in all quantum objects, which is to say, in all physical reality. Yuji Hasegawa, a physicist at Technische Universität Wien in Austria, reminds us that “the uncertainty does not always come from the disturbing influence of the measurement, but from the quantum nature of the particle itself." Advances in technology may someday minimize observer effect but cannot remove indeterminacy on the quantum level.

    Similar hiding places exist in the macro-world. Even systems that are fully deterministic— weather systems, for example—remain unpredictable because we can never have a complete knowledge of initial conditions. Snoke points out that this kind of unpredictability holds for quantum systems as well.

    In the Unknowability of the State of Matter

    We cannot see into the smallest places dues to quantum uncertainty and observer effect, but neither can we see into the largest places. Even apart from quantum uncertainty, the universe is simply too large for us to understand. Both the initial state of any system in the universe and its current state are beyond our grasp.

    According to Randy Isaac, former executive director of the American Scientific Affiliation and VP of Science and Technology at the IBM Thomas J. Watson Research Center, the universe is so large and there are so many variables, we can only know it on a statistical basis. Isaac points out that one mole (a standard measurement equal to the number of chemical units found in 12 grams of Carbon-12) of a substance – that is, 6 x 1023 – “is so inconceivably vast that there is no hope of knowing the attributes of each molecule in even a minute but macroscopic amount of substance.”

    If there is no hope in knowing the attributes of each molecule in a minute amount of substance, what can be said about every molecule in the known universe, which is currently estimated to be about 46 billion light years across? There are hiding places everywhere."
    The heart of the human problem is the problem of the human heart.

    Another quote from the same article that I like:
    C. S. Lewis addressed this dynamic in Mere Christianity: “God will invade. But I wonder whether people who ask God to interfere openly and directly in our world quite realise what it will be like when He does. When that happens, it is the end of the world. When the author walks on to the stage the play is over. … For this time it will God without disguise; something so overwhelming that it will strike either irresistible love or irresistible horror into every creature. It will be too late then to choose your side. There is no use saying you choose to lie down when it has become impossible to stand up. That will not be the time for choosing; it will be the time when we discover which side we really have chosen, whether we realised it before or not.”
    The heart of the human problem is the problem of the human heart.

    And that is exactly why we require the help of quantum computers. They will give us the ability to run simulations that will help us develop a better understanding of the quantum world and our own world.

    We are at a critical point in our history. We are getting close to developing an electronic version of the human brain. Once we have that, we will be able to create brains that will be smarter than us, and use those to solve some of the hardest problems that exist, including the quantum world.
    The only unknown is if those electronic versions will be able to establish self awareness, or not.
    And if they are, we might be into a lot of trouble.
