Has anyone looked into what they're doing over at CERN with the large hadron collider?

Here are two links which discuss their new discoveries.

I believe this ties in with string theory and how there's possibly 11 different dimensions around us.

Neither discovery relates to string theory. The light interacting with itself confirms a prediction of quantum electrodynamics which is a theory Richard Feynmann and others won the Nobel Prize for in the 1960's. The other article concerns the potential identification of a new hadron. A proton is an example of a hadron most people would be familiar with. They are made of smaller particles called quarks. This is kind of just a new arrangement of those.

Unfortunately the LHC doesn't operate at energies high enough to test string theory directly. For that you'd need an LHC like the size of a planetary orbit or something crazy like that.

LHC is baller tho

What are the possibilities or hopes with the large hardon collider? Do they believe one day this machine will be able to test string theory?

Directly no, indirectly yes maybe:

This article explains issues pretty well although its a bit dated because they've started somethings this article says they were going to start doing:

The main use of the LHC is to prove theories.
But right now it mostly searches for postulated sub atomic particles (higgs) and the interactions between them.

String theory and so on is still very difficult to prove.

I think they are getting ready to search for supersymmetry in nature at 13TeV (an extension of the standard model where fundamental particles have a more massive partner). They also want to measure the mass of the top quark with more precision to know if the vacuum state of our universe is stable or if it can decay (if it can the point of space where the vacuum decays first will expand outward at the speed of light destroying everything, well never know what hit us). It is puzzling that as measure now we can only tell that we are close to the border case of being stable, but need more precision to know for sure.
Sometimes I wonder since neurons may make use of quantum effects if someone on a psychedelic trip could trigger a vacuum decay event. Hopefully not.
