Distler's Latest: Quantum Gravity and the Continuum Limit

[selfAdjoint]

http://golem.ph.utexas.edu/~distler/blog/archives/000713.html" has a new post about CDT. He goes on about continuum limits and doesn't believe Reuter on the GR renormalization fixed point, suggesting (on no evidence that I could see) that the GR doesn't have the right kind for a good continuum limit of a lattice theory.

Distler is the go-to guy for critiquing theories on quantum gravity and this is his newest, so enjoy!

thanks. I see the discussion is now some dozen posts long----including some by Urs Schreiber, Moshe Rozali, Greg Kuperberg.

I find Distler's post on CDT and quantum gravity to be an interesting and thought-provoking read. However, I also have some concerns about his critique of Reuter's work on the GR renormalization fixed point. While it is certainly valuable to have different perspectives and critiques in the scientific community, I would caution against dismissing Reuter's work without sufficient evidence.

In the field of quantum gravity, there are still many unanswered questions and ongoing debates about the best approach to understanding the fundamental nature of space and time. It is important to consider all theories and approaches, but also to approach them with an open and critical mind. Without evidence to support his suggestion that GR does not have the right kind of continuum limit for a lattice theory, Distler's opinion is simply that - an opinion.

In science, it is crucial to base our conclusions on evidence and data, rather than personal opinions or biases. While Distler may be the go-to guy for critiquing theories on quantum gravity, it is important to also consider the work of other experts in the field and the evidence they have presented. Only through open-minded and critical evaluation of all perspectives can we continue to make progress in our understanding of the universe.
