Prospects and Limits For the LHC's Capabilities To Test String Theory
StartsWithABang writes: The Large Hadron Collider has just been upgraded, and is now making the highest energy collisions of any human-made machine ever. But even at 13 TeV, what are the prospects for testing String Theory, considering that the string energy scale should be up at around 10^19 GeV or so? Surprisingly, there are a number of phenomenological consequences that should emerge, and looking at what we've seen so far, they may disfavor String Theory after all.
String Theory is the result of an attempt to rectify QM and Relativity using pure math. It was not born from evidence. So, evidence will; be its undoing,
If string theory does end up being proven, they're going to have to be careful not to overwrite the null terminator, or the universe will sigsegv.

"The production of tiny black holes is one of the predictions. "
No concerns at all with that one.
Man I hope they know what they are doing.
"Who are you?" "No one of consequence." "I must know." "Get used to disappointment."
Aren't there like 40 things called string theory, ranging from merely odd or unlikely all the way up to batshit crazy?
I've gotten the sense over the years there's so many things called string theory you can't coherently say what any of it is, or how you'd test it.
Hell, I'm not even convinced many physicists take it seriously. Which means for the layperson, it mostly sounds like gibberish.
It just has all the hallmarks of being so unexplainable as to be meaningless. Which I'm sure is grounded in my lack of understanding due to the fact that it's so magical as to be unexplainable.

The problem is, that there are 10^520 possible variations of string theory models that can represent our universe, and if we fail to find any of the results 'predicted' by string theory, then string theorists can just re-arrange the variables in their models, and pick from one of the other 10^520 variations - and can shift the goalposts like this pretty much forever, unless we have the gigantic breakthrough in string theory research, that we've been waiting for 30 years already, with no end/hope in sight...
It's not uncommon to hear among physicists critical of string theory, that we could be centuries away from falsifying the theory - even millenia.

After all?

Why the switch to GeV? Stick with a prefix and call it 10^16 TeV.

Microscopic black holes disappear quickly due to Hawking radiation. So if your goal is to destroy the earth, creating a microscopic black hole is not the way you want to go.
The bigger a black hole is, the more slowly it evaporates. So if you want your black hole to do any damage, it'll have to be more than a certain threshold size. Turns out that minimum-size black hole you'll need to destroy Earth is roughly the mass of Mt Everest.
If we take the density of such a black hole to be 3 * 10^18 kg/m^3, then our black hole will look like a ball with a radius of about 12 cm, i.e. it looks like a soccer ball.*
See here for more details.
* no idea if my density assumption is reasonable. I'm not a physicist -- I got the number from 20 seconds of googling. The volume of your black hole may vary.
...he was making a game reference, and what he got are unforeseen consequences. Sounds about right to me.

Much more than 40!
For every string theorist, there are two string theories (something to do with pair production....).
There are several mistakes in the article as well. Supersymmetry is not a consequence of String Theory. It was invented to explain the huge difference between the Higgs mass and the energy scale where gravity becomes important (the fine-tuning or hierarchy problem). It was only after its invention that String Theorists realized that they needed it to make their theories work. In fact it is entirely possible that Supersymmetry exists and String Theory does not whereas the reverse is far less likely so it is wrong to say that SUSY is a consequence of String Theory.
Similarly the use of String Theory to solve non-perturbative QCD is not some new, fundamental principle but is simply a result of applying the maths developed for String Theory to a different problem. Hence studying the quark-gluon plasma is, at best, a test of some of the maths developed for String Theory but really tells us nothing at all about the physics. For a simpler analogy if you demonstrate that calculus works this does not imply that Newton's Laws of Motion are correct even though calculus was co-invented by Newton so he could write down and apply his laws.
Dude If that thing spawns an "Earth eating black hole" living next door to it would be like about Mars. What everybody forgets is a blackhole has conservation of mass, charge and angular momentum, so a blackhole whizzing around the LHC ring would act pretty much like every other thingy whizzing around with the same mass, charge and angular momentum. Even if the blackhole escaped the ring, it would only be a blackhole as long as it's energy was high enough to maintain it's event horizon; that energy is dependant on it's velocity, which is a vector involving speed and direction! Yeah that's right a quantum blackhole can un-blacken if it collides with another particle and loses energy, it can un-blacken through Hawking radiation and it's only black if your close enough to it's direction of travel.

If you'd like to actually know something about string theory, I suggest watching some of Leonard Susskind's lectures:
https://www.youtube.com/watch?...
You will then be in the position of being able to intelligently criticize the theory, instead of quoting other people's jibes.
Susskind is not interested in bullshitting anyone, by the way... quoting from memory: "This is why a lot of us found string theory to be so promising. And it keeps promising and promising."
You are making a (literal) surface judgement based on your own prejudices. You have conveniently ignored all other factors and accepted race as being the real driver, even when a rational person would evaluate all the evidence. If you looked at poverty instead of race, you would see that black people are far more likely to be poor, and poor people are far more likely to commit crimes. But that would not let you be a racist fuckhead, so I can understand why you ignored that and just went with your gut instinct of lazy, lazy racism. Your parents must be proud to have raised such an illogical, hate-filled muppet.
Maybe the GP is female and enjoys having a real cock in her pussy, instead of the spaghetti noodle hanging off your crotch.
nicely put.
i'm proud of yer, son,
Can't we muster a popular appeal against posting vapid articles from medium.com here? Please? Or at least post them with a mandatory icon warning people that this is heavy on glossy pictures and light on worthwhile information?
Who writes this stuff anyway? Clearly somebody with a strong interest in big photos of impressive looking things; whereas I suspect that most of us would be far more interested in good, solid, factual information, without illustrations, unless strictly needed. Is it 'samzenpus'? Does he/she have a glycerine complex?
52% Of convicted murderers are black, is what he is trying to say, i think. In America, that would make a black person 700% more likely to commit murder than any other race.

I'm not even a physicist and i could tell that string theory was BS just from listening to the proponents talk about it on documentaries.
