A Quote by Robert Charles Wilson

From this new point of view, the universe I had inhabited became an object I could perceive in its entirety. It was a hypersphere embedded in a cloud of alternative states - the sum of all possible quantum trajectories from the big bang to the decay of matter. "Reality" - history as we had known or inferred it - was only the most likely of these possible trajectories. There were countless others, real in a different sense: a vast but finite set of paths not taken, a ghostly forest of quantum alternatives, the shores of an unknown sea.
You can't change your life. This mode in literature goes against the more middle-brown mode, which is about shaping your destiny, changing it. You can't change it, you just become passive in front of it. Even if we live in a godless universe, there are paths set, there are trajectories, like bumper cars just pulling those trajectories, colliding.
Quantum physics presents a new and exciting worldview that challenges old concepts, such as deterministic trajectories of motion and causal continuity. If initial conditions do not forever determine an object's motion, if instead, every time we observe, there is a new beginning, then the world is creative at the base level.
We couldn't build quantum computers unless the universe were quantum and computing. We can build such machines because the universe is storing and processing information in the quantum realm. When we build quantum computers, we're hijacking that underlying computation in order to make it do things we want: little and/or/not calculations. We're hacking into the universe.
In quantum mechanics there is A causing B. The equations do not stand outside that usual paradigm of physics. The real issue is that the kinds of things you predict in quantum mechanics are different from the kinds of things you predict using general relativity. Quantum mechanics, that big, new, spectacular remarkable idea is that you only predict probabilities, the likelihood of one outcome or another. That's the new idea.
Nevertheless, all of us who work in quantum physics believe in the reality of a quantum world, and the reality of quantum entities like protons and electrons.
The history of the universe is, in effect, a huge and ongoing quantum computation. The universe is a quantum computer.
Quantum Mechanics is different. Its weirdness is evident without comparison. It is harder to train your mind to have quantum mechanical tuition, because quantum mechanics shatters our own personal, individual conception of reality
I favour an interpretation of quantum mechanics (the 'Everett interpretation') according to which reality branches in any chancy quantum situation. On this view, Schrödinger's set-up will give rise to in two future branches of reality, one with a live cat, and one with a dead cat - and the talk of '50% chances' just indicates that the two branches are both equally real futures of the cat that originally entered the box.
It was a dogma throughout most of the 20th century that quantum science only applied to subatomic matter, and we now know that not to be true. One of the major discoveries was Quantum Holography.
The most important application of quantum computing in the future is likely to be a computer simulation of quantum systems, because that's an application where we know for sure that quantum systems in general cannot be efficiently simulated on a classical computer.
According to quantum field theory, fields alone are real. They are the substance of the universe and not 'matter'. Matter is simply the momentary manifestation of interacting fields which, intangible and insubstantial as they are, are the only real things in the universe.
All the analysis of infinite reality which the finite human mind can conduct rests on the tacit assumption that only a finite portion of this reality constitutes the object of scientific investigation, and that only it is 'important' in the sense of being 'worthy of being known.

I saw that everything, all paths I had been following, all steps I had taken, were leading back to a single point - namely, to the mid-point. It became increasingly plain to me that the mandala is the center. It is the exponent of all paths. It is the path to the center, to individuation. I knew that in finding the mandala as an expression of the self I had attained what was for me the ultimate.
The quantum fluctuations within a zero-point field can start the process that builds the process, which builds into matter, an irreversible process. We have some evidence that suggests that. We don't have a Big Bang, but we have a lot of little pops! A continuous set of little pops!
One can imagine that God created the universe at literally any time in the past. On the other hand, if the universe is expanding, there may be physical reasons why there had to be a beginning. One could imagine that God created the universe at the instant of the big bang, or even afterwards in just such a way as to make it look as though there had been a big bang, but it would be meaningless to suppose that it was created before the big bang. An expanding universe does not preclude a creator, but it does place limits on when he might have carried out his job!
