Will the LHC find any strings?
« on: 03/09/2008 09:10:05 »
Will the LHC find any strings? If not, what are the odds of ever being able to test any string/M theory? Physicist Lee Smolin says there are 10^500 string theories ("The Trouble with Physics," Houghton-Mifflin, 2007). How do we know which one is correct? Maybe they're all correct and we live in 10^500 universes simultaneously. That could be confusing.

I'm pretty sure that the LHC is far too weak to probe strings.

Hello Supercryptid

That's what I thought. So will we ever be able to test any string or M type theories with their branes,blobs, bulks and leaking gravity? If Smolen is correct and there are 10^500 string theories, where are we in this line of thought? Perhaps Hugh Everett III's "Many Worlds" interpretation of quantum reality can be supported by a universe where all 10^500 string theories can be correct. Maybe Schrodinger's cat is dead under one string theory and alive under another.

I know some of you members are into string/M theory. I would like to hear from you regarding Smolin's position.

The LHC will find what it finds - and that's what we're all waiting for  ;D

LHC reminds me of 'Deep Thought' building a computer to finding out the meaning of life, the universe and everything.

Actually, the analogy could be taken even further - Deep Thought designed the Earth, as a computer, incorporating organic lifeforms into it's operational matrix (that's us) to find the answer [via us building the LHC]

C'mon guys! If the LHC can't find strings, how can it find the meaning of life?

Is this what you mean perhaps about the 10th September 2008's
Big Bang with the LHC in CERN.

Also the BBC are broadcasting a whole day about this, I will be listening or watching as much of it as I can.

It is so interesting.

The problem is, if they don't/cant find any then what happens next?

If they cant detect any then does that mean they don't exist or will the explanation be that the LHC is not powerful enough?

Personally I don't think they will find any proof.

The LHC doesn't have the power to find strings. A collider powerful enough to find strings would probably fill the orbit of Neptune (I don't know this, its just that it's well beyond the LHC). What the LHC might well find is evidence of the long sought Higgs boson. The danger with the LHC is not that it will destroy the world, but it might destroy the Standard Model of physics if the Higgs doesn't have the predicted mass.

There is a chance that the LHC will find strings.

In a warped extra dimensional theory proposed by Randall & Sundrum, it is possible that strings could be found at around 1000GeV rather than at the Planck mass which is 1017 times greater. This theory proposes that gravity is weak compared to the other forces due to dilution in a warped higher dimension and that gravity will become strong at 1000GeV.

This is the same basis for the belief that the LHC may produce 5-dimensional micro black holes.

Thanks for the informative response and the paper. I was hoping that the LHC might shed some light on M Theory. I'm rather skeptical about string theories, but I'm keeping an open mind. Que sera, sera.
