You/we just dont know enough yet. people used to think of aristotle physics, the same as we think of modern physics. Its great, maybe not perfect, but very close. There is no way modern physics is even close. We are no different from our predacessors. What makes us so damn special?
quote:Originally posted by daveshortsIt is possible that people in 2500 will think our theories primative, but unless they are living in very different conditions to those we are in now the every day physics they use will have to be very similar to ours.eg, quantum mechanics and relativity both give approximately the same answers as Newtonian mechanics at ordinary speeds, temperatures and length scales.This has to be true as they are all explaining the same set of results in this region. In the same way any year 2500 theories may have to explain a load of new phenomena we don't know about, but they will still have to explain all the phenomena we have already noticed so will have to give approximately the same answers as our theories most of the time even if they are based on an entirely different principle.
quote:Originally posted by syhprumI think Nexus puts forward a sound argument for the non existence of gravitons but I believe there is adequate evidence for the existence of dark matter from light lensing observations as well as galatic rotationsyhprum

quote:Originally posted by bostjanwhy is the existance of gravitons absurd?i think string theory is very beautiful, even though i have a handful of issues with some of the details. any experiment to directly observe string theory would require too much energy, but there ought to be clever ways of indirrect observations. unfortunately, i feel skeptics will deny any evidence without coming up with any conter-theories.
quote:Originally posted by Soul SurferYou seem to have a totally negative attitude Nieuwenove all the theories you mention have been proposed to deal with anomalies in observations and our models of the universe. To return to your original premise that scientists are following them like sheep. If you read the litereaure you will understand that they most definitely do not do this because there are almost as many theories as there are people working on them so unless you can offer something more positive I suggest that you go away and occupy your mind with a subject more to your tase towards which you may be able to propose positive contributions.
quote:Originally posted by Soul SurferOK then I will pose a final question, if you think that they are totally on the wrong track would you be prepared to suggest what might be the right track.I myself consider that some of the suggestions are inelegant and probably wrong but I do believe that there is an honest effort to design experiments to validate all the significant theories. For example, the August issue of Astronomy and Geophysics has a long and thorough review of experimental techniques to provide independant verification and measurement of the effects of dark energy by several independant methods.Learn, create, test and tellevolution rules in all thingsGod says so!
