Main Question or Discussion Point
Can loop quantum gravity tell us something about the recent phenomena of the neutrinos?
I would say Not. Modern LQG has a manifestly Lorentz invariant formulation.Can loop quantum gravity tell us something about the recent phenomena of the neutrinos?
Also, LQG is not a theory of everything, unlike string theory. In particular, it is not a theory of Italy.Carlo Rovelli's comment on the alleged finding by OPERA was "In Italy everybody disregards the speed limit, OK? Let's wait for confirmation before we take this seriously."
It certainly contains Italy, Greece, Germany and other European countries b/c thanks to all these extradimensions it's the first theory that helps us to understand where all the money goes ...So, string theory is a theory of Italy too? It is good to know that it contains Italy, as it seems that it doesn't contain other things.
You might like to review the ways phenomenologists have proposed to test Loop cosmology by observation.Isn't it something embarrassing that a theory of everything can't give us a testable experiment??
This is to my knowledge.
Just to clarify, I'm not against string theory, I think that even if some day someone can prove that it's or isn't a theory wrong, it will leave something productive for the humanity, I think that it is not a waste of time.In direct answer to your question, Casco, YES it is embarrassing when theorists spend time elaborating theories which cannot, even in principle, be empirically tested. One gets the feeling that it should be against the rules, maybe it is. A betrayal of the trust we place in them. A departure from the centuries-old scientific tradition. Which if allowed to continue could endanger something more precious than their own careers.
If you want a link to some test-related papers let me know and I will fetch one.
Fine. This is not a perfect list. It probably gets some wrong ones and misses some good ones.And the references about what you're talking about, I'm interested if you can give them to me it would be great.
