Angels or Demons? LHC Up Without Fear of Black Holes

With the official opening of the Large Hadron Collider only days away, much of the world, in particular the physics community, are turning their attention Switzerland’s way. However all the way back across the Atlantic in Illinois, is the Tevatron particle collider at the US Department of Energy's Fermilab, who have themselves made a giant step forward in the search for the Higgs-boson particle.

The Higgs-boson particle is going to be the focus at the LHC, among other things. The Standard Model of particle physics predicts the existence of a particle, known as the Higgs boson, which gives mass to other particles. Currently, the mechanism by which particles acquire different mass values is unknown, and finding evidence for the existence of the Higgs boson would solve this fundamental mystery of nature.

Scientists working on the DZero particle detector experiment have successfully observed pairs of Z bosons, elementary particles that mediate the weak force, at the Tevatron. Given the difficulty of not only producing a pair of these particles, but then observing them, this is a big step towards observing the Higgs-boson itself. In fact, the DZero detector had to search through some 200 trillion particle collisions to find this one pair.

However, just a week after this huge discovery was made, another such discovery was made at the Tevatron. DZero and CDF scientists at the Tevatron ruled out the possibility that the Higgs-boson could have a mass of around 170GeV/c2. This is a huge discovery, because this is within the range that many scientists believe the Higgs may have, thus eliminating the need to search in that area. A similar discovery was made back in 2000, in the Large Electron -Positron Collider at CERN, when a mass of 114GeV/c2 was ruled out.

"We now know that the Higgs boson does not have a mass of 170GeV/c2," explains Dr Gavin Davies from Imperial's Department of Physics, co-leader of the Higgs hunting group on the DZero experiment. "If it did have this mass, then we should have seen evidence for it at the Tevatron by now. Ruling out possible masses of the Higgs is a very important part of the hunt for this elusive particle."

"It shows that the Tevatron experiments are very much in the race for finding the Higgs," added Dr Davis.

Another physics discovery came from the LHC, where the possibility of a stable black hole was ruled out. Steven Giddings, of the University of California-Santa Barbara, and Michelangelo Mangano, of the European Organization of Nuclear Research (CERN) have ruled out any possibility that a stable black hole – ie, one that has the chance to stabilize, and start eating matter around it – is non-existent.

"We went to great pains to thoroughly investigate possible risk in even some very outlandish proposals for black hole behavior, and found we could safely rule it out,” Hiddings explained to PhysOrg.com. “The basic reason is simple: Nature has been performing this type of experiment for billions of years, not only on our planet and sun, but also on much denser objects, like neutron stars and white dwarfs. Their enormous age reassures us that physics doesn't exhibit the bizarre behavior that LHC opponents have suggested."

Does nature produce these mini black holes in the same way or should I worry some initial coditions may be somewhat different ?
If the Boson has mass could it be eaten or merge with the black hole ?

Famous last words by authority figures could make a sci fi movie.

MOVIE "THERES NOTHING TO WORRY ABOUT"

Scene I

HAPPY LHC PEOPLE CELEBRATING , DRINKING SCHNAPPS AND CHAMPAGNE

Meanwhile , inside the LHC the Mother of all Big BOSONS is eaten by black hole which goobles up the LHC but major scientists and authority figures escape by UFO contingency spacecraft to another galaxy ... to build another Type IV Civilization .

The End

Why haven't ET'S contacted us yet ? They should have been here already !

Because the type IV Civilizations are always destroyed by scientists that say "Trust me there's nothing to worry about ... Weve got everything ubder control"

The aliens ARE here, and have been here since 1947. See "The Disclosure Project" at http://www.disclosureproject.org. (And please, folks, if you're going to flame me on this, at least watch the video first. The six hundred people who testified at the Press Conference have quite a lot to say.)

As to why the aliens aren't stopping the work at the LHC, I would guess they either don't think it's a big deal (I don't, either), or they want to see what happens!

Move along folks - nothing to see here. Except possibly some of the Universe's more esoteric aspects. If I had the qualifications, I'd LOVE to work on such a project. How much energy does the LHC use ? I find myself curious about that.

Could we find new ways of generating energy via the actions of subatomic particles ? That question just occured to me. We need a " Rodney McKay " type to figure that out.

There was a debate in a prior article here about this, and I wrote about the risk of the dimensional merging here, I think now that the dimensional merging or the transformation of matter would explain the cost of this, the scientific adventur is not valuable the cost, I think.Well, at leat three projects in three places of the earth at the same time.

Could a way be found to harness quantum energies, or some such ? Or have I been watching too much " Stargate Atlantis " & " Eureka " ?

Enlighten, if you will .....

New colliders are thought to help to discover and demonstrate physicsbased on maths only.
Colliders however can be rather dangerours : both the Eurean LHC and the American one.
What about if during an experiment of collisions a strage thing like a 'local black hole' would be created ???
If they (scientists) aready know everithing and know any outcome about collisions at very high speed then why to spend such incredible amount of money to bulid them ??
NO they do not know and we do not know if 'something strage' happens how they are going to control it.

Why They (scientists and policy makers) do not concentrate their brave and smart brain and expenditures for large machines on the issue of energy lack on this planet ?????
This is main and severe issue for us and for the people of next age.

Is LHD usefull in regards of creating new energy ??

I would suspect the answer is NO...Not at all.

Sorry for those at CERN and at US equivalent machine.

I am in deep disgreemet of what is physics and to what issue it should aim to.

If earth became a black hole, its size would be like a tennis ball.
When a atom or lesser become a black hole, what would that be?
Isnt it stretching the laws of matter and to what?
Could it be a portal?
To another dimensions?

Dear claudio casuccio,
A lot of scientists are already working to address the "issue of energy lack on this planet ". We do need other physicists to discover the beyond. When Faraday showed demonstrated electromagnetic induction, a person who asked him what is the point of immersing himself in this knick-knack and his answer was the possibilities. You cannot throw the baby with bathwater. Many times, scientists find out new things and it's only years later that their discovered principles become technologies which are vital to the humankind.

Secondly, though scientists already 'know' everything[sic] and 'know' any outcome about collisions at very high speed (these I quote frm you), it is only from theory. Though their theory (wiki: Standard Model) is pretty sound, they need to know if their theory holds true for high energy collisions. That is how it is in science. To verify/falsify the theory with experiments. Also, the mathematics behind the theory predicts a particle called Higgs Boson, and they want to verify its existence.- if not they need to revise. One historical example I want to give Einstein's theory of relativity to Newton's mechanics. Newton's laws are still used today: from cars, sports, to rockets. But Einstein came up with a more general framework that works as well when things go near 300000000 meters per second. And one product of new theory is laser, e=mc2 etc.

Physics is a fundamental science that seeks to discover the truth about nature. I deeply fear for the day when physics is just about addressing the current issue. when all the scientists do is to find out the Energy solution. Then, i can say we won't have much hope for the future. Bear in mind that sometimes, the answer lies in most unexpected places.

With my regards,
Sandar
