    While I was at it, I added pointer to

    • Roger Penrose, On the stability of extra space dimensions in Gibbons, Shellard, Rankin (eds.) The Future of Theoretical Physics and Cosmology, Cambridge (2003) (spire)

    and

    • Roger Penrose, Fashion, Faith, and Fantasy in the New Physics of the Universe, Princeton University Press 2016 (PP:10664)

    and took the liberty of adding a critical comment on the claims about moduli stabilization made in these texts (here)
