Bekenstein has joined the list of physicists who claim that a specific laboratory experiment can measure quantum gravity effects. He is now member of the club of the "fantasy quantum gravity researchers" who have left reality. The club is growing, and includes more and more researchers.
The club is another popular dead end, similar to supersymmetry. But Bekenstein had already left reality with his MOND work.
Since years, Bekenstein, a gifted researcher with exceptional intuition, intelligence and courage, is not working on anything that is related to the real world. What a sad story.
