But, they wouldn't change the paper and minimized their error, even though the claim that they have wrong is in the very title of their paper. This pretty much totally offends the entire process of posting pre-prints at arxiv.org, and the entire peer review process. So, she wrote a blog post that will track back to the paper.
You might get away with the impression that we have here two unfortunate researchers who were confused about some terminology, and I’m being an ass for highlighting their mistakes. And you would be right, of course, they were confused, and I’m an ass. But let me add that after having read the paper I did contact the authors and explained that their statement that the LQG violates the Holographic Principle is wrong and does not follow from their calculation. After some back and forth, they agreed with me, but refused to change anything about their paper, claiming that it’s a matter of phrasing and in their opinion it’s all okay even though it might confuse some people. And so I am posting this explanation here because then it will show up as an arxiv trackback. Just to avoid that it confuses some people.
The offending authors are Ozan Sargın and Mir Faizal, and the paper is: "Violation of the Holographic Principle in the Loop Quantum Gravity" http://arxiv.org/abs/1509.00843.
