antimatter Posted June 17, 2008 Share Posted June 17, 2008 I was recently reading a few articles about String Theory, and how it's 'permanently safe' because it cannot be tested. This bothers me in a way, because it's not really science if it can't be tested. I thought about this a little, but unfortunately I don't know enough of physics to really get anywhere, but what possible experiments can be done to prove String Theory. Apparently the problem is in: A. How small strings are B. The massive distances Does anyone have any ideas on how it can be tested/experiment-ified?

Klaynos Posted June 17, 2008 Share Posted June 17, 2008 People are working on devising experiments for string theory... And some stuff at the LHC could falsify most if not all string theories... It bothers alot of people... Link to comment Share on other sites More sharing options...
Royston Posted June 17, 2008 Share Posted June 17, 2008 I found a couple of non-technical articles, neither give much detail, but string theory does appear to be heading towards experimental scrutiny...I'll try and dig up something more recent. http://www.sciencedaily.com/releases/2007/01/070124175443.htm http://public.web.cern.ch/public/en/lhc/WhyLHC-en.html Link to comment Share on other sites More sharing options...
antimatter Posted June 17, 2008 Author Share Posted June 17, 2008 And some stuff at the LHC could falsify most if not all string theories... How so? Link to comment Share on other sites More sharing options...
Klaynos Posted June 17, 2008 Share Posted June 17, 2008 How so? By falsifying supersymetry... It'd still leave ALOT of string theories standing though, but would cut the field down massively. Link to comment Share on other sites More sharing options...
timo Posted June 17, 2008 Share Posted June 17, 2008 You could only falsify susy-models that cast a suitable upper bound on the masses of the superpartners (note that this is a necessary not a sufficient condition) or the Higgs-boson. I don't know strings but I doubt that they do. With "different string theories" are you refering to different values of the free parameters or to really different theories?

Klaynos Posted June 18, 2008 Share Posted June 18, 2008 Different values of the free parameters I believe. Link to comment Share on other sites More sharing options...
