Quand à Nottale, Rovelli, etc. ce sont pour le moins des auteurs controversés.
a quel propos ?
La théorie de Nottale, personne n'en parle. La théorie de boucle a un peu plus de succès, mais si on regarde ce que disent des théoriciens réputés qui ne sont pas adeptes de la langue de bois (David Gross) on
obtient par exemple ceci:

I was attending Strings2021 and yes Gross is right. Basically there has been no concrete development in LQG research in the last 15 years, that is still stuck with relatively trivial problems it can't solve like finding GR from it or the BH entropy corrections. In the meantime, string theory has developed in a huge way from all points of view: AdS/CFT and holography are understood better than ever, the research in swampland helped clarify the link between strings and the very mathematical consistency of general theories of quantum gravity and F-theory was crucial in finding whole classes of standard model like solutions in stringy model building. The comparison between the two can't even be done, it would be like comparing a cruise ship to a life
buoy.
