P.S. So maybe they're all wrong?
If they're all wrong, they'll be very bitter and angry with the person who tells them so.
People, not person.
Maybe I have been completely misunderstood what theory building is about. I have understood it as a genuine attempt to understand, as an intellectual game in which different ideas compete. Also fun. A lot of good luck is needed to get the correct idea. The proposal of putting to jail the people who are not so lucky looks to me strange. I have said critical words about string theory but I would not like to see either stringies or loopies in jail.
"... I would not like to see either stringies or loopies in jail."You are a kinder person than me.
I wonder how the intergalactic gas would change the refraction index. If a GRB light crossed several galaxy planes, wouldn't one expect some delay?
It's probably better to say both give two inequivalent glimpses at some more fundamental theory.
Hi kneemo. In some sense, I suppose so, but if we are talking specifically about the Fermi results then it is reasonable to say very concretely that LQG dispersion will be proved wrong.And in lecture 2A Nima-Arkani Hamed, in his usual exaggerated style, bets his life that Fermi et al will find no kind of Lorentz violation - so it would be a real shame if he was proven wrong - but c'est la vie.
