Anders,
How certain can we be that these limitations are completely insurmountable ?
I say this as I notice that historically, scientists and the like are most
eager to use the "impossible" stamp, only to take it back in the future due
to some unprecedented workaround or something - such as parallel computing
moving the upper limit of computation speed in computers, or the
"impossible" sound barrier simply being broken. What I know for damn sure is
that there's no way scientists know everything about information processing,
sensing abilities and information storage at this time, much as they might
like to think they do. What I'm saying is that the way in which we approach
these problems, and the technologies implemented, will almost certainly end
up changing in time as old methods are superceded - and who can say what
this will mean for "absolute limits" calculated based upon the current
paradigm.
For instance, (I could have the wrong end of the stick) I notice that in the
commonly available explanation of quantum uncertainty, the provided analogy
goes something like this:....Supposing you want to measure 2 different
aspects of a system for a calculation requiring 2 measurements...blah
blah.....you'd have to shoot a proton at.....blah blah.....then by the time
the second measurement is taken......blah blah....this and that changed,
measurements out of step, incalculable.
So, because we can't think of a way of doing it right this second, it can't
be done, therefore absolute uncertainty exists. It seems to me that this
assumes an invasive method of measurement, linear and constantly progressing
time, etc....etc...
It certainly cannot be said that these things will always be out of our
control.
In fact the whole idea of probability becomes null if time manipulation
becomes possible!
Rob.
PS If you know of any good internet resources on the reasons given for these upper limits, I'd be extremely interested to have a look!
