Registration is now open for the conference "Puzzles in the Quantum Gravity Landscape: viewpoints from different approaches". Besides plenary talks, plenty of time will be devoted to discussions at the interface between QG and EFT. https://t.co/2GuuaeBGjE

[Alessia Platania @abplatania]

@ThomasVanRiet2 Agree with the overall message of the post, but as a note, asymptotic safety is not ok with any matter content. E.g., too many fermions/scalars would destroy the fixed point/UV completion https://t.co/Wqh9iu9tD7 (this is 1 famous paper, but there are many)

[Alessia Platania @abplatania]

@ThomasVanRiet2 @GregTrayling @Kaju_Nut [of course something more extended, focused on string theory, would be nice!]

[Alessia Platania @abplatania]

@ThomasVanRiet2 @GregTrayling @Kaju_Nut In our lectures in QG, we have a section on FAQ in QG. In it, there is also a part on string theory (mostly written by Ivano Basile), where some of the most common criticisms of string theory are addressed. https://t.co/H9FjtSpanb

I just supported a crucial cause that aims to enhance scientific education in Palestine. Every bit helps. Please consider sharing or donating. It really makes a difference. https://t.co/YHTlTizET6

@stringking42069 @AlessandroStru4 nope! it does not need to.

[Alessia Platania @abplatania]

@stringking42069 @AlessandroStru4 I think you are very confused about what Asymptotic Safety is! :D (maybe you are referring to quadratic gravity). I suggest you to always look for some literature before publicly embarrassing yourself!

[Alessia Platania @abplatania]

@stringking42069 Apparently, you are among those who need to read the lectures from top to bottom ;) "fuq" highlights the unprofessional and empty nature of your statement. The existence of biases in QG (of which you just provided evidence) highlights the need for programs like the Nordita one!

[Alessia Platania @abplatania]

@AlessandroStru4 @stringking42069 but thanks for spotting the missing ref, that is still good to add!

[Alessia Platania @abplatania]

@AlessandroStru4 @stringking42069 Most of the criticisms are misconceptions that have been clarified both with John (see for instance his new statements on AS in recent papers, which are different than in that old paper) and in this paper: https://t.co/OzQyt14ooy More work is of course needed (as in any field).

[Alessia Platania @abplatania]

The "Lectures in Quantum Gravity" and the "Visions in Quantum Gravity" are out!
These are two contributions associated with the Nordita Scientific Program "Quantum Gravity: from gravitational EFTs to UV complete approaches".

Enjoy the read!

[Alessia Platania @abplatania]

@ThomasVanRiet2 yes! Higgs mass arXiv:0912.0208, top mass
arXiv:1707.01107, but also quark masses' difference
arXiv:1803.04027.

[Alessia Platania @abplatania]

@ThomasVanRiet2 This does not exclude that there are other "consistency bubbles" in the space of QG theories, where things work differently. One should always investigate all seemingly consistent frameworks and be open-minded! [sorry for the multiple replies, apparently X forbids long texts]

[Alessia Platania @abplatania]

@ThomasVanRiet2 I cannot find anymore your comment about coincidences, that I saw previously from my phone. I also do not believe in coincidences, so if ST can compute and match those 2 coeffs, that is great, and supports both ST consistency and the standard thermodynamical interpretation of BHs

[Alessia Platania @abplatania]

@ThomasVanRiet2 @malcfairbairn There are stronger conceptual arguments that BH thermodynamics is "different" in AS, but I do not want to spoil too much of my upcoming paper :) (also, there are assumptions behind, and one can discuss their validity as well).

[Alessia Platania @abplatania]

@ThomasVanRiet2 @malcfairbairn The argument in that paper is not super strong, it can be avoided if the UV fixed point is non-local (which we think is the case in AS).

[Phil Halper (aka Skydivephil) @skydivephil]

Do we live in a fractal universe? Leading physicists explain Asymptotic Safety , the quantum gravity theory that predicted the Higgs mass. https://t.co/N9MRP52B7Y #physics #quantumgravity

[Niayesh Afshordi @nafshordi]

Could this be the coolest thing ever? Yes, it could!

Another great video by @skydivephil featuring @abplatania and @AstridEichhorn on one of the most attractive and minimalistic approaches to quantum gravity
