Good comments NEJ.
It is a good thing that popular science is so readily available to us all. Unfortunately many people find it hard to distinguish between well established science and speculative hypotheses.
This isn't helped by some writers who need to sell books and lazy journalism.
String theory is one example of an idea that is still lacking in evidence and yet I have lost count how many times I have been told on this forum that "scientists have discovered there are 11 dimensions".
