Six months ago, a new paper announced that:

In a new paper published in Physics Letters B, Ahmed Farag Ali, Mir Faizal, and Mohammed M. Khalil explain that the key to finding parallel universes may come from detecting miniature black holes at a certain energy level. The detection of the mini black holes would indicate the existence of extra dimensions, which would support string theory and related models that predict the existence of extra dimensions as well as parallel universes.

"Normally, when people think of the multiverse, they think of the many-worlds interpretation of quantum mechanics, where every possibility is actualized," Faizal told Phys.org. "This cannot be tested and so it is philosophy and not science. This is not what we mean by parallel universes. What we mean is real universes in extra dimensions. As gravity can flow out of our universe into the extra dimensions, such a model can be tested by the detection of mini black holes at the LHC. We have calculated the energy at which we expect to detect these mini black holes in gravity's rainbow [a new theory]. If we do detect mini black holes at this energy, then we will know that both gravity's rainbow and extra dimensions are correct."
...
Using gravity's rainbow, the scientists found that a little bit more energy is required to produce mini black holes at the LHC than previously thought. So far, the LHC has searched for mini black holes at energy levels below 5.3 TeV. According to gravity's rainbow, this energy is too low. Instead, the model predicts that black holes may form at energy levels of at least 9.5 TeV in six dimensions and 11.9 TeV in 10 dimensions. Since the LHC is designed to reach 14 TeV in future runs, these predicted energy requirements for black hole production should be accessible.
...
"If black holes are not detected at the predicted energy levels, this would mean one of three possibilities," Khalil explained. "One, extra dimensions do not exist. Two, they exist, but they are smaller than expected. Or three, the parameters of gravity's rainbow need to be modified."

So, the time for this experiment has come - now, or next week - and anticipation is high: https://uk.news.yahoo.com/large-had...nd-a-parallel-universe-081239407.html#zTTS3DO

On 60 Minutes the scientists said today that they have been unable to detect any mini black holes so far. My guess is string theory will fizzle.

I watched 60 minutes. But was multi-tasking so must have missed the comment about being unable to detect mini black holes :).

It was fun watching the tour of the LHC again and hearing the stats.

Good, as I expected. Finally physics will be able to free itself from this 40-year old string theory dead end street which never had been a good idea to begin with. But it will be a mighty and protracted struggle; too many long and 'distinguished' careers have been spent on this for scientists to let go easily. Scientists are human too, after all.

Fortunately, no Nobel Prizes have been given for string theory. Oh, forgot, Nobel Prizes are only awarded for provable results. String theory has never had any shred of evidence going for it.

Yeah, points two and three are the typical evasive strategy that string theorists have employed for decades. "We haven't found anything yet, BUT..." Seems almost like a scam to me, but they really seem to believe in this nonsense. Fortunately, the LHC can now become, next to a machine yielding spectacular positive results, e.g., Higgs Boson, the Great Debunking Machine.

I saw the 60 Minutes segment last night when they were questioned about extra dimensions and string theory. They stated that they found nothing in the latest collisions to suggest mini black holes but "that didn't mean they don't exist" :)
