Could the Large Hadron Collider really act as telephone for talking to the past?

Spurs-a-jingle boffins in America say that the Large Hadron Collider (LHC), most puissant matter-rending machine ever assembled by humanity, may also turn out to be the first time machine ever built. According to the physicists’ calculations, instruments at the mighty particle-smasher may soon detect signs of “singlets” which it has not yet generated, sent back from their creation in the future.

“Our theory is a long shot,” admits physics prof Tom Weiler, “but it doesn’t violate any laws of physics or experimental constraints.”

According to calculations by Weiler and his colleague Chui Man Ho, if the LHC manages to generate the long-theorised but never actually seen Higgs Boson (aka “the god particle” – confirmation of its existence was a major reason for the Collider’s construction) it should also create another mysterious particle dubbed the “Higgs singlet”*. These singlets, according to Weiler and Ho, might be able to move in a fifth dimension transverse to our existing four-dimensional continuum – thus they could pop out of our universe and subsequently re-enter it elsewhere in time.

This thinking relies on the idea that the 4-D continuum we can perceive exists within a 10- or 11-dimensional universe, rather as a flat two-dimensional membrane could float suspended in normal three-d space. Versions of the so-called “M-theory” in physics hold that this is the case, but that almost all kinds of forces, waves, particles etc are stuck to the four-dimensional membrane, aka the “brane” for short.

CERN launche new blog on Quantum Diaries platform

CERN is launching a new blog on the Quantum Diaries platform. Until now Quantum Diaries was focussed on providing a platform for individual particle physicists from around the world to post their thoughts on work and life. Today CERN and other particle physics laboratories have joined by launching official institutional blogs. Quantum Diaries is an initiative of the Interactions collaboration, a joint communication resource from the world’s physics laboratories.

LHC experiments bring new insight into primordial universe

Geneva, 26 November 2010. After less than three weeks of heavy-ion running, the three experiments studying lead ion collisions at the LHC have already brought new insight into matter as it would have existed in the very first instants of the Universe’s life.

The ALICE experiment, which is optimised for the study of heavy ions, published two papers just a few days after the start of lead-ion running. Now, the first direct observation of a phenomenon known as jet quenching has been made by both the ATLAS and CMS collaborations. This result is reported in a paper from the ATLAS collaboration accepted for publication yesterday in the scientific journal Physical Review Letters.

A CMS paper will follow shortly, and results from all of the experiments will be presented at a seminar on Thursday 2 December at CERN. Data taking with ions continues to 6 December.

Researchers at the Large Hadron Collider (LHC) are getting set to create the Big Bang on a miniature scale.

Researchers at the Large Hadron Collider (LHC) are getting set to create the Big Bang on a miniature scale.

Since 2009, the world’s highest-energy particle accelerator has been smashing together protons, in a bid to shed light on the fundamental nature of matter.

But now the huge machine will be colliding lead ions instead.

The experiments are planned for early November and will run for four weeks.

The LHC is housed in a 27km-long tunnel on the Franco-Swiss border and is managed by the European Organization for Nuclear Research (Cern).

The collider consists of four different experiments and one of them, ALICE, has been specifically designed to smash together lead ions.

The goal of these collisions is to investigate what the infant Universe looked like. Colliding protons at high energies was aimed at other aspects of physics, such as finding the elusive Higgs boson particle and signs of new physical laws, such as a framework called supersymmetry.

Cern’s spokesman James Gillies told BBC News that besides ALICE, the ATLAS and Compact Muon Solenoid (CMS) experiments will also be temporarily colliding ions.

Big Bang

He said the tests could provide an insight into the conditions of the Universe some 13.7 billion years ago, just after the Big Bang.

They will look at the Universe fractions of a second after a tiny but very dense ball of energy exploded to create the cosmos as we know it today.

Scientists believe that it was back then that a special state of matter existed, different from the matter the Universe is formed of now.

“Matter exists in various states: you can take a material like water and if you deep freeze it, it’ll be solid, and if you put it on a table, it’ll turn into a liquid, and if you put it into a kettle, it’ll turn into a gas,” said Dr Gillies.

“It’s all the same stuff, but those are different states of matter. And if you take materials into laboratories, you can pull the electrons off the atoms and you have another state of matter which is called plasma.”

But at the very beginning of the Universe, there might have been yet another state of matter. Physicists have dubbed this “stuff” the quark-gluon plasma.

“And this is the state of matter you have if you’re able to effectively melt the nuclear matter that makes up atoms today, releasing the things that are inside, which are quarks and gluons,” Dr Gillies explained.

CERN completes transition to lead-ion running at the LHC

Four days is all it took for the LHC operations team at CERN to complete the transition from protons to lead ions in the LHC. After extracting the final proton beam of 2010 on 4 November, commissioning the lead-ion beam was underway by early afternoon. First collisions were recorded at 00:30 CET on 7 November, and stable running conditions marked the start of physics with heavy ions at 11:20 CET today.

“The speed of the transition to lead ions is a sign of the maturity of the LHC,” said CERN Director General Rolf Heuer. “The machine is running like clockwork after just a few months of routine operation.”

CERN – potential new discovery spotted by Atom smasher scientists

GENEVA — Scientists at the world’s biggest atom smasher said Tuesday they appeared to have discovered a previously unobserved phenomenon in their quest to unravel the deepest secrets of the universe.

Results from one of the detectors in the Large Hadron Collider experiment indicated that “some of the particles are intimately linked in a way not seen before in proton collisions,” the European Organisation for Nuclear Research (CERN) said on its website.

“The new feature has appeared in our analysis around the middle of July,” physicist Guido Tonelli told fellow CERN scientists at a seminar to present the findings from the collider’s CMS (Compact Muon Solenoid) detector.

“We have today submitted a paper to expose our findings to the wider (scientific) community,” he added, underlining caution and the need for the peer review outside CERN.

Nonetheless, Tonelli, a physicist from Italy’s University of Pisa and scientific spokesperson for the CMS detector, underlined that during weeks of cross-checks and critical debate among the team, “we didn’t succeed to kill it.”

The phenomenon showed up as a “ridge-like structure” on computer mapping graphs based on data from billions of proton collisions in the 3.9-billion-euro (5.2-billion-dollar) machine.

The 27-kilometre (16.8-mile) circular particle accelerator buried under the French-Swiss border is recreating powerful but microscopic bursts of energy that mimic conditions close to the Big Bang that created the universe.

The CMS, one of six experiments around the accelerator, is designed to search for for the elusive and so far theoretical Higgs Boson, commonly nicknamed the “God Particle”.

It is also aimed at shedding light on components of dark matter, the mysterious invisible void that makes up 26 percent of the universe.

MIT physicist Gunther Roland, one of the authors of the paper submitted for review, described the latest observation as a “a subtle effect in a complex environment — careful work is needed to establish its physical origin.”

“What we really hope to get is not just ideas, but how to test it,” he added during the seminar at CERN’s headquarters on the edge of Geneva.

The organisation said it bore “some similarity” with observations in a smaller Ion collider at the US Department of Energy?s Brookhaven National Laboratory.

Despite applause from their peers at CERN, the CMS team’s interpretation of the observation on Tuesday was vigorously challenged during the meeting as scientists bounced suggestions off each other.

“We are stating facts, facts that there is something that we have not seen before,” Tonelli responded, as they began the process of seeking endorsement and an explanation for the observation.

MoEDAL becomes LHC’s seventh experiment

As reported from CERN 12th May 2010

The MoEDAL experiement inside the LHCb VELO cavern.

MoEDAL collaboration.

MoEDAL is the newest of the experiments that will investigate particle collisions at the Large Hadron Collider. Approved by the CERN Research Board in December, the MoEDAL experiment will search for very specific exotic particles.

The experiment is relatively small, cheap and quick to install but its physics potential is huge. The MoEDAL detector will consist of layers of plastic attached to the walls and ceiling of the cavern that houses the VELO detector of the LHCb experiment. Physicists will look for tell-tale collinear ‘etch-pits’ created by a stable particle such as a magnetic monopole or a massive stable supersymmetric particle crossing through the plastic.

The international MoEDAL collaboration, made up of physicists from Canada, CERN, the Czech Republic, Germany, Italy, Romania and the US, have already installed the first square metre of plastic in the LHCb cavern and are preparing to deploy the rest of the detector during the next planned long shutdown of the LHC, which will start late in 2011.

Origin of the Universe

Humans have always sought to understand the origin of the Universe, and the origin of Consciousness. How did the Universe originate? How did consciousness originate? Was consciousness there from the beginning, or did it evolve out of something else? Ever since man stared at the stars above, these questions have persisted.

Discussing the origin of the Universe at first glance may seem like it is quite remote from healing, but in fact the topics are strongly linked.

Let your imagination take you on a trip to what we can visualize as the beginning of time and space, before the Big Bang. All that existed was the most reduced state of energy, constantly flowing in a seemingly random fashion, yet synchronized at some level. This reduced state of energy had been flowing for an infinite amount of time prior to the Big Bang. With no physical matter present, there was only an infinite amount of empty space with energy rippling through it.

Empty space is not really empty at all. Even in a vacuum cooled to near absolute zero, there are still vast amounts of energy within that space. Scientists have theorized that there is enough energy in empty space the size of a cup, to boil all the oceans on earth. These are quantum fluctuations, or spontaneous movements of energy in empty space. Energy is present in the form of waves, meaning it ripples like water in a pond, except in all directions.

Ripples or quantum fluctuations of energy have an effect on each other. Random pulses of energy interact as they bounce off or intersect with each other. Imagine watching ripples in a pond during a rainstorm. Sometimes the ripples converge and form a larger ripple. Eventually these energy fluctuations accumulate at intersections thereby increasing the concentration of energy in a specific area.

When these ripples converge, this can result in the waves “amplifying” each other. If this happens, you then have a region of space with a higher concentration of energy. With a higher concentration of energy you have a heightened probability of a particle being manifested from the energy in empty space. This increases the prob­ability of a quantum particle being manifested from energy fluctuations. Eventually a certain frequency hits the concentrated area, which causes energy to compress, and a quantum particle is created. This instantaneously ini­tiated the Big Bang. As this all occurred at once, it could be more accurately said that we are all from a common energy rather than a particle. I refer to this as a particle for simplicity of understanding.

How can something come from nothing? For some reason, a lot of people tend to arbitrarily classify matter as being something and energy as being nothing. This of course could not be further from the truth. Matter is simply energy when it is broken down (E=MC2). It has been mathematically proven how a particle can be manifested from the energy fluctuations in empty space. Recently scientists have managed to generate a particle solely out of this energy. It is therefore completely possible for matter to manifest from this energy. The prob­ability of these quantum fluctuations lining up in this specific way, which produces matter, is infinitesimally small but there was an infinite amount of time prior to this event.

When the fluctuations intersected in a specific way, the first quantum particle was created and instantly the Big Bang occurred. The origin of the Universe is a natural process evolving from the first particle. Every particle in the entire Universe originated from this common energy.

The mechanism that initiated and drove the Big Bang is actually quite simple. With the manifestation of the first particle, there was the beginning of gravitational force. This gravity pulls in more energy, which manifests more particles. As the number of particles increases, so does the gravitational pull, thus pulling in even more energy.

The initiation of the Big Bang chain reaction was not a “particle”, but was simply quantum energy fluctuations that somehow slightly manipulated the space/time continuum. With the correct conditions, this allowed the cre­ation of the first quantum particle. All matter is simply energy oriented in a way so that it forms a “bend” in the space/time continuum, which essentially is a playing field for matter as it follows the bends in space/time also known as gravity.

Gravity does not pull in the energy directly. Time passes slower around a gravitational field and therefore energy leaves the region of space slower than energy flows in. Although the first singularity may have been a subatomic particle, this small gravitational field was enough to initiate these events because prior to this point there was no gravitational field.
