Have a look at the overview article arXiv:1108.3269 "An introduction to quantum gravity" by Giampiero Esposito.
It lists 16 approaches to quantum gravity that were followed in the last 80 years - string theory is one of them. Then it lists their achievements. All are theoretical! Not a single of the achievements is a testable prediction.
Yep, quantum gravity is a dead alley. We all can stop reading gr-qc.

Another theoretician left reality
This theoretician is too little-known to be named. He dislikes the strand model. But for a simple reason: He thinks that time has two dimensions.
This seems too crazy too be true. But some people get paid for saying and writing such nonsense. Modern research is full of nonsense.

The next theoretician goes bonkers
This theoretician is too well-known to be named. When asked what he thought about the strand model, he answered that the strand model of a black hole could not be correct, because it does not work in 5 and 6 dimensions.
This answer is worth meditating. A physicists says, in writing, that a description of nature is wrong because it does not describe certain cases that have no relation to reality. He could equally say that F=ma is wrong because the equation does not describe Santa Claus or resurrection.
With this way of thinking the theoretician has maneuvered himself into the land of fairies. There is no way that he will ever be successful in finding a theory of quantum gravity.

Another theoretician goes bonkers
Vongehr is one of those people that wrote papers that nature has two times. He means two-dimensional time. No joke.
Experimental backing? Zero. That a guy writing this has studied physics at university is almost unbelievable. Some people have a degree and still cannot count.

Multiverse and polytheism
One can dispute whether the equivalence between the universe and god is accurate. Pantheists assume that universe and god are two words for the same concept. Einstein was a pantheist in this sense.
Assuming pantheists are right, the people that talk about the multiverse are reintroducing polytheism. It becomes clear again what a nonsense the concept of multiverse is.

String theory and chess
Searching for the theory of everything with string theory is as promising as searching for it by playing chess.
Both string theorists and chess players are extremely smart people. Chess players are impressive. So are string theorists. They have intelligence to spare. All of them talk about their intelligence like pistoleros talk about their guns. They are die-hard machos.
The only issue: their occupation does not help finding the theory of everything. Not at all. Being smart does not count in the search.

"Too early to despair"
said Guido Altarelli about the latest LHC results. Of course, he means the opposite. He is disappointed. A lot.
But I am not. I enjoy the situation of being right while almost all other experts are wrong. It will never happen again, in physics.
The next results will appear at the Bombay conference, end of August 2011. Great.

Another theoretician goes bonkers for a while
Supersymmetry is not confirmed by any experiment, not even by the LHC. What does a theoretician say? Urs Schreiber answers: The 1922 Stern-Gerlach experiment, which established spin 1/2, is a proof that world-line supersymmetry exists.
The reasoning is so blatantly false that I must ask: how can a smart man like Urs Schreiber write something so false? We all wish you that you recover soon. Find a caring person that helps you!

No endless frontier
After the numerous results presented a few days ago, it is obvious that no deviation from the standard model has been found. Despite of thousands of experimental physicists looking for the opposite, with the promise of fame and riches.
Particle physicists are stunned. Nothing new or unexpected has been found. How can this be?
The answer has been given in this blog for some time now. Particle physicists believed, without reason, that the domain of high energy is an "endless frontier", which allows new discoveries whenever an order of magnitude in energy is gained. But this belief is wrong.
The belief in an endless frontier is wrong for two reasons. First of all, it contradicts the idea that nature is comprehensible. If nature is comprehensible, there also is a moment in time where we understand it all. And this moment seems quite near. But secondly, the belief in an endless frontier contradicts quantum theory. Quantum theory tells us that there is a finite amount of energy in any finite volume of space, that there are a finite number of degrees of freedom in a finite volume of space.
Quantum theory states that nature is finite in its microscopic domain. Quantum theory tells us that there is NO endless frontier in the microscopic domain. In other words, quantum theory tells us since 100 years that there is NO endless frontier in high energy physics.
The LHC experiments simply confirmed this result. And they confirmed the strand model yet again.
