We are told that empty space is seething with energy - energy that suddenly appears from nowhere and disppears into nowhere
Where does it come from, where does it go to? And we are told that energy is simply another form of mass, so we actually witnes (if we have the right instrumentation) the creation of matter out of nothing!
We are told that masses attract one another and we call this gravity
But why? Why on earth do they attract?
We are told that entangled particles communicate with one another instantaneously and on the radio the other day I heard a physicist saying that he was working on this so that man could send information instantly across any distance using these entangled particles
Isn't this all very odd and doesn't it show that ther are many things that we are simply incapable of understanding?
Doesn't this mystery beyond our comprehension raise the possibility of a being with superior knowledge that does understand these things, indeed understands all?

I think what it shows is that our current grasp of reality is very incomplete and that we have to extend our models of what is 'real' in order to accommodate these mysteries. Unfortunately, although we can theorize about what underlies the things you have mentioned, the scientific method has no way, currently, of testing such theories but, hopefully, one day will have progressed to the point of doing so. In the case of an all-knowing supreme being, this will always remain in the area of belief and, therefore, we cannot apply objective reality to it. Personally, I feel we will be forced to continue to develop our ideas about a multidimensional universe in order to progress our understanding of phenomena that eludes us at the moment.

PA, did you happen to see the Horizon programme the other day called Defeating the Hackers? Towards the end they interviewed a researcher who had produced a quantum computer based on the concept that an electron can be in more than one place at a time, thus allowing more than one simultaneous calculation and so make code cracking much faster. The bottom line is that the computer worked. At the moment it is an early proof of concept model, but the designer is pretty sure that it can be "geared up". The point I am making is that as obscure as these concepts seem to be, they appear to be demonstrably correct. Who knows how long it will be before the secret of how entangled particles communicate is discovered? I just wish that I were young enough and had sufficient grey matter to be able to immerse myself in this very complex field! btw: The prog is here- www.bbc.co.uk/programmes/b0391z20P |

It's my understanding that quantum computing is analogous to having great numbers of 'ordinary' computers working on the same problem at the same time but in 'other worlds' or parallel universes. How it is possible to retrieve the solution to a particular problem, however, is completely beyond me.
In mathematical terms, if you were to represent a piece of information by, say, two bits, i.e., a 1 and a zero (10) in a conventional computer then in terms of a quantum computer the equivalent number of bits would be 2^2, that is to say 4 bits instead of 2 in the conventional case. 3 bits would be represented by 2^3 in a quantum computer, 4 bits would be 2^4 (16 bits) and, as you can see, 64 bits (which is fairly standard in today's computers) would be in the order of 2^64 bits in a quantum computer, which is a vast improvement on the number of bits an ordinary 'classical' computer could handle. We talk in terms of 'qubits' to describe quantum bits rather than bits. This is all due to the fact that in quantum computing a bit can be both 1 and 0 at the same time, whereas in the ordinary world it has to be one or the other, not both.

Thanks for the link . I look forward to viewing it |

Molte interassante Now in conventional computer numbers such as 10 12 and 10 -12 are commonly used. Such numbers take 111011100110101100101000000000=28 bits Therefore in a quantum computer such numbers would require 2 28 bits =268435456 bits (0.26 billion bits). The mind boggles Moreover as each qunatum bit can be either 0 or 1 then the number of possible answers to such a problem would be 2 28^28 ( think) |

Philosophically, quantum computing seems to show us that matter at the very fundamental level (particles such as photons and electrons etc.) exist not only in our universe but are spread across many other universes, otherwise where does the quantum computing take place? It certainly cannot take place in our three dimensional universe since in an ordinary computer a bit can only take the value of 1 OR 0, not both simultaneously. This 'superposition' of particles that exist at different places at the same time certainly challenges our traditional ideas about how reality works and the idea that the universe is really just a very complicated clockwork machine, something popularized by Newton and others, has been completely blown out of the water and for me makes reality a much richer thing to contemplate. I often wonder if our brains have the ability to produce quantum processes because things like inspiration and creativity have never really been explained so could it be that some people have access to information that originates in some place other than the everyday one? After all, nature has had millions of years to exploit what we have now discovered to be part of the natural order of things. Who knows?
