Large Hadron Collider set for March restart at 13 TeV

MSNBC - Steven Hawking Warns Doomsday

Stephen Hawking says the ‘God Particle’ that scientists believe created the world could actually end it, too.

The particle – know as Higgs boson – “has the worrisome feature” that it could become unstable at extremely high energies and create a “black hole” that would collapse the universe, the legendary British physicist has warned in a new book titled Starmus, according to the Daily Express.

“This could happen at any time and we wouldn’t see it coming,” Hawking claimed in the book.

Now that I've got your attention with the doom porn ... the rest of the story is that it would take a collider the size of the Earth to make a particle that could destroy everything.

As for the angels or demons crawling out of a hole ... I wouldn't mind a window that we can look and see other dimensions. That would be awesome. (well .. as long as the critters on the other side of the window didn't open it up and crawl through).

The higher kinetic energies effectively bring scientists closer to the “Big Bang” moment of creation of the universe.

Honest question.

At what point do we get to close to the big bang?

Has that been determined or are we just guessing our way along and claiming things should go as we plan?

With all things there is a dangerous amount so what is that amount in this case.

......boys and their toys......
Grins!

Some friends of mine are all doom-porn over this but I'm personally more worried they are going to take out the EU power grid. Of course the "hey bubba watch THIS! jokes are still funny.

Scared of Bill Nye?
Bwahahahahahahahahaha

What's the worst that can happen? the later cuts a hole in the foundation?.....A couple of particles escape?
It'll be fine.....

They'll write it up an publish in New Scientist an about three people on the planet will understand it.

So is just a little bit of a big bang ok then?

I do not think in the context of particles colliding that there will be no repercussions.

Sure they can call it safe now because the effects are small enough to go unnoticed by us but i think there is also a very dangerous point between what the collider was runing at before and one the size of earth. Blindly finding that point may go down as the death of science. (and us but just slower than the big bang)

The greatest epic fail of all time is that the big bang is a theory but the collider is not.

Ask Switzerland. It's their country that could get the 'little bit of a big bang'.
Us on the other side of the planet ... not so much.

a reply to: FlyersFan

I do not think that is true.

Think about what steve is saying.

A collider the size of earth is equal to all the energy in the universe

So only a fraction of that would be necessary to damage the planet.

I know i am not up to speed on all this but perhaps they believe there is a certain point which damage happens.

If so i think they could express that level to stay away from.

Thanks. Here you go, some doom porn that was 'posted three minutes ago' when I just looked up news about the restart:

www.inquisitr.com...

Reports that CERN scientists will restart the powerful Large Hadron Collider (LHC) in March, 2015 for another three-year long run of high-energy collision experiments have reignited longstanding fears that the experiments could destroy the Earth and even possibly the entire universe.

Fears that high energy collision experiments with the LHC, the world’s largest particle accelerator located in the Jura mountains near the Franco-Swiss border, could trigger an Earth-wide or even universe-wide catastrophe have been increased by news that the newly upgraded LHC will generate particle collisions at nearly double the energy level previously achieved.

how do they presume that is going to happen? Black holes? They occur naturally all over the universe and they have yet to cause a catastrophe.

The higgs Boson walks into a church and the priest says 'hey we don't allow your sort in here'
He replies 'but without me you can't have mass'..oh dear.

;


LOL Quantum physics humor. Gotta love it.
Know why Leon Ledderman called it the God particle? Because they wouldn't let him call it the God damned particle !!!

Best doom porn since Ison.

Go Shiva!

Seems legit.

Here we have a thread about the long-awaited restart of one of the few greatest experimental machines (or group of machines) in mankind's history, and the posters fall back into the doom porn mode. Well, never mind, the value of this restart is in what will be discovered and found in the first several minutes, days, months, or nanoseconds. I for two can't wait until the Collider starts up again and begins to show results (twiddling thumbs until March).

My bad..Im always in doom porn mode.

I hope they do something good with the technology.. rather than using it to design something like the H-bomb's big brother.

a reply to: Aleister

I think my question is logical and a correct answer would frame things better.

At what point does the collider become dangerous???

a reply to: deadeyedick

If it falls on your foot.

Until then, it isn't dangerous, it's one of the scientific wonders of mankind.

a reply to: Aleister

Not to be rude but that is an ignorrant statment that will only feed the doom.

a reply to: deadeyedick

There is no doom. The LHC does not have the capacity to create doom. It creates science.

Hopefully, LHC working at the new, higher energy will confirm that the asymptotic behaviour as q^2 --> infinity of the proton form factor F(q^2) is q^(-4 ), where q is the change of momentum. This will be strong evidence that quarks are not fundamental, as currently assumed, but are composed of three much smaller objects ("preons" or "subquarks").

a reply to: micpsi

I don't understand the math, but do understand that quarks are obviously not 'the' fundamental particle (or energy). There are several kinds of quarks, which by definition means that they are made of other particles (or energies). I didn't know that a higher LHC run might be able to refine the question, so thanks, and appreciated. Please keep us informed.

Your first ignorrant statment was funny but this one is very close to being a lie.

There is a danger in all things.

The question remains at what level of energy does such actions become dangerous.

a reply to: deadeyedick

I personally have no idea, but my guess from reading about it and what little understanding of the science that I do have is that the LHC doesn't have the capacity to do something which would be dangerous. Even though it's part of the LHC's name, it's not large enough to do anything which will put people or the world in danger. If I could be there at the start-up, standing a few feet from where the action is going to take place, I'd jump at the chance. This will be a historic moment in science.
