Hmm. I was quite serious when I asked, am I missing something, in my last post.
You seem to have a view point of someone who works in the science field. So are you saying that some of these theories are flawed?

First of all, for clarities sake, I am not a scientist, I never went to university. But I keep myself abreast of developments where possible. Certain
elements of the student safety and the quality of education at both my primary and secondary schools, were... less than ideal, so despite deep
interests in astrophysics and fair familiarity with the basics of other sciences, I have no qualifications in any of them, aside from GCSE's in
science and psychology.
I do however, subscribe to a monthly science and technology publication, and read heavily on subjects that interest me in my spare time. I have
learned more in my own time than I ever did in school. It is my own little rebellion against the efforts of my nations government to promote idiocy in
the majority of young people at the time of my institutional education.
However, even bearing that in mind, I can tell you that new theories are being developed all the time, and with the discoveries being made by
projects running out of the LHC at CERN, the very fabric of what we know, will be, is being re-written. It may not be that all the old theories we
know of will completely die, some will be amended. The key thing to grasp about theory is what the word means, and how it differs from assumed fact.
Essentially all a theory is, is a working principle, assembled from observations that have been made, explanations of observed phenomena based on
working knowledge. When that working knowledge changes, so does the theory, until such time as the theory becomes so amended that it is ridiculous to
continue to use it. For an example, see the change in perception and understanding that came about when it was widely accepted that the Earth was an
oblate sphereoid, rather than a flat disc, that the Earth orbits the Sun, and not the other way around. You will note that well before we understood
WHY the Sun appeared to rise and set, and seasons came and went, we were still, as a species, able to farm land, plan crops, make calendars and the
like. But after that time, we were able to make better informed guesses about the way the universe worked, even on the rudimentary basis of the time.
Many of the early astronomers made discoveries, and had thoughts, which are still key to the study of the stars today, because those theories were a)
simple in thier elegance, and b) have been validated and made stronger, the more we have learned, and now, in this day and age, they are as real and
basic to science, as air and breathing are to those who do not participate or hold an interest in that field.
Theories like relativity are not FLAWED if they happen to be proven incomplete, because a discovery made with an ultra modern, totally new piece of
apperatus reveals something strange and outside the bounds of that theory. Einsteins E=mc2 came under threat relatively recently (did you see what I
did there?) when a neutrino, tracked between two points, APPEARED to have traveled faster than light during an experiment, but as it turned out later,
the apperatus was faulty.
That said, there are people working on theoretical propulsion methods which echo those used in the television show, Star Trek, utlising localised,
controled gravity wells, to drag and push a craft along, between two bubbles of warped space, folding space time both toward and away from a vehicle,
in order to sidestep Einstiens pesky theories.
Pluto is no longer a planet, and heres the kicker, the real evidence for the fact that science is truely changing its accepted models of the
universe. Less than four decades ago, most people, despite the sci-fi, in the field of astrophysics were pretty adamant that there was no other life
in the universe, because we had never seen signals from anywhere else, and because we knew of no other habitable planets.
With new teloscopy methodology however, and gravitational lensing techniques, space exploring space telescopes have seen vast numbers of potentially
habitable planets, whose atmospheres appear (at this great distance) to be rich in various life relevant minerals. Also, we keep discovering
increasingly hardy bacteria and even multicellular lifeforms which survive outrageous environments. We now know of a critter (called a Waterbear if I
recall correctly) which can lay eggs which hatch in a cold vacuum, and it and its off spring will survive that environment for quite a time, much
longer than you or I would, thats for sure.
There are even some microbes which REQUIRE uranium (I think thats the element they need) to live. Our understanding is expanding constantly, and
never ceases to grow. Never doubt it, not even for a moment!
