Uh. Particle physics is a NATURAL PROCESS, subbo. Our experiments are relatively weak.

Another turgid rehash of things we already know from Mr. Siegel?  Fetch me my fainting goats!

Though, on a positive note, who wouldn't like this gif?

Particle physics can already destroy us with a little uranium

Particle physics won't have the opportunity, basic chemistry will destroy us first.

Yeah.  Considering that 'Particle Physics' is what makes frickin' NUCLEAR WEAPONS work, I don't think we need a super-LHC to give us cause for concern on that front.

Basically, we don't have to worry about blowing up the Universe because, well, it already has.

You do risk quantum entanglement with other universes of course....

That is nuclear physics. Particle physics works is about things that are more fundamental.

What do they collide in CERN?

Most of the time protons.  Occasionally they do nuclei. But at no time is anything the LHC doing anything even remotely relevant to someone designing or making a nuclear weapon.

I probably should add that utterly nothing the LHC discovers is expected to have any practical applications.  Okay maybe if the data guides physicists to a correct theory of everything then maybe decades later there will be an application we can't yet dream of.

In any event let me copy and paste Wikipedia's section on the beams. For more detail, go there and check out its references.

The LHC physics programme is mainly based on proton-proton collisions. However, during shorter running periods, typically one month per year, heavy-ion collisions are included in the programme. While lighter ions are considered as well, the baseline scheme deals with lead ions[42] (see A Large Ion Collider Experiment). The lead ions are first accelerated by the linear accelerator LINAC 3, and the Low Energy Ion Ring (LEIR) is used as an ion storage and cooler unit. The ions are then further accelerated by the PS and SPS before being injected into LHC ring, where they reach an energy of 2.3 TeV per nucleon (or 522 TeV per ion),[43] higher than the energies reached by the Relativistic Heavy Ion Collider. The aim of the heavy-ion programme is to investigate quark-gluon plasma, which existed in the early universe.[44]

Needless to say, quark-gluon plasma is simply irrelevant to nuclear bombs and indeed nuclear anything. Nuclear fusion and fission are not studied at LHC.

atoms

they have a 3 or 5 or 7 or 8 mile tunnel loop, walls lined with magnets, they accellerate atoms through multiple loops before engaging more magnets to make the atoms collide, so they can record the subatomic particles that appear when they smash into each other at nearly the speed of light

/a boson walks into a church and the loser says "we don't allow bosons in here" so the boson says "without me there'd be no mass!"

That's what I thought but
apparently even smaller stuff too.

I thought they got several trillion degree plasma by using nuclei collisions
