Id been swimming in a luxurious, long, deep pool in the San Fernando Valley at. 83° by a thermometer in the water while 100°+ in the air.
Sitting in the Sun, feet dangling in the water, I could see the lights refracted patterns (Snells law) from its surface along the bottom of the pool.
Id seen video documentary mock-ups to show how existence looks at or near the Planck Scale. Yet here and now was an example even clearer.
Envisioning part of the pool bottom as a slice of “quantum” space, filaments fleeted into existence, each having been created by that gone before and out of them. And bits of brightness, (again, reflections of the Sun along the surface, cast on the bottom and sides) would move along the length of each segment, intersecting with their ends, such strings quickly dissipating here, and reappearing there with each such interaction.
Moreover, from my calves and feet, there would enter waves of interference that would yield to the strings an even greater sense of overall excitation. This too might be seen as a representation of the Uncertainty Principle where at the quantum level, virtual entities come into and go out of existence, yet perhaps summing to an actualization of reality, which however even billions of years hence, may as likely decay and zap back into the void from whence they came.
And Id bet too that this could all be worked out mathematically.
But, as I said, its merely a representation of such conditions, which is all that can ever be achieved at the Planck Scale anyway. So as this lazy days imaginings gave rise to other waxings, into the water I went, even in that second of submergence, to childhood again.

[snip] To get the same amount of acceleration seen by astronomers, Greene and Levin calculate that the extra dimensions should have a scale of about 0.01 millimetre. Dark energy would be hiding less than a hair’s breadth away... Eric Adelberger and his team at the University of Washington in Seattle, US, have run a series of experiments using a twisting pendulum to measure the short-range strength of gravity, and they have already ruled out extra dimensions larger than a 0.1 millimetre.

London - Google's search engine is already the dominant player in the internet query business, with over 70% of all search engine hits beginning there, according to seoconsultants.com. In an effort to further cement their dominance, Google has introduce two new refinements to its search engine as of March 24, 2009. Both of these improvements are related to the use of searches with longer strings of keywords.
Google has now added a "searches relate to:" selection at the bottom of a search's results page. These are, in effect, searches that relate keywords in a query to completely different keywords that have a semantic connection. For example, a search for "physics theories" will return a suggestion to search for "string theory," "quantum mechanics," and "newton's laws."
The second improvement is the addition of longer snippets from each website returned by a query. These text descriptions have any and all keywords highlighted, so that a searcher can more quickly determine if a given website does indeed contain that for which they're looking. The longer the search query, the more context Google will return for each site found.
Both of these improvements should help Google retain its dominance in the internet search engine field.

Physicists Say Can Find No Sign of 'God Particle' LONDON (Reuters) -- After years of searching and months of sifting through data, scientists have still not found the elusive sub-atomic particle that could help to unravel the secrets of the universe, a science magazine said on Wednesday.The Higgs boson, the missing link which could explain why matter has mass and other fundamental laws of particle physics, is still missing -- and physicists fear it may not exist. -- -- It's more likely than not that there is no Higgs,'' John Swain, of Northeastern University in Boston, told New Scientist magazine.Scientists have been searching ...

GENEVA (Reuters) -- Europe's top particle physics research center has taken a major step in its plan to build the world's biggest "particle smasher" which it hopes will eventually unlock the secrets of the origins of the universe. On Wednesday it inaugurated a huge bottle-shaped vault which will house Atlas, an enormous detector of the micro-items of matter that make up life, the universe and everything. Atlas, standing as high as a four-story building and twice as long, will almost fill the cavern, cut into rock beneath meadowland straddling the Swiss-French border outside Geneva. The giant piece of machinery will...

A scientist says one of the most sought after particles in physics -- the Higgs boson -- may have been found, but the evidence is still relatively weak. Peter Renton, of the University of Oxford, says the particle may have been detected by researchers at an atom-smashing facility in Switzerland. The Higgs boson explains why all other particles have mass and is fundamental to a complete understanding of matter. Dr Renton's assessment of the Higgs hunt is published in Nature magazine. "There's certainly evidence for something, whether it's the Higgs boson is questionable," Dr Renton, a particle physicist at Oxford,...

The physics lab that brought you the Web is reinventing the Internet. Get ready for the atom-smashing, supercomputing, 5-gigabits-per-second Grid Economy. 200 feet underground, a proton does 17-mile laps at nearly the speed of light. Guided by powerful magnets, it zooms through a narrow, circular tunnel that straddles the Switzerland-France border. Then a tiny adjustment in the magnetic field throws the proton into the path of another particle beam traveling just as fast in the opposite direction. Everything goes kerflooey.

Researchers from the University of Rochester have helped measure the elusive top quark with unparalleled precision, and the surprising results affect everything from the Higgs boson, nicknamed the "God particle," to the makeup of the dark matter that comprises 90 percent of the universe. The scientists developed a new method to analyze data from particle accelerator collisions at Fermilab National Accelerator Laboratory, which is far more accurate than previous methods and has the potential to change the dynamics of the Standard Model of particle physics. Details of the research are in today's issue of the journal Nature. "This is a...

What are the chances of physicists finding the Higgs boson at CERN or intelligent life on Titan by the end of the decade? Six-to-one for the Higgs and not very likely for life on Titan according to New Scientist magazine and bookmakers Ladbrokes, who have joined forces to offer the public the opportunity to gamble on a range of scientific projects. "Physics bets are not just the preserve of big names like Stephen Hawking," says Valerie Jamieson of New Scientist, "now everyone can join in". Last month Hawking, who is famous for placing bets on physics with colleagues and co-workers,...

Physicists are hunting for an elusive particle that would reveal the presence of a new kind of field that permeates all of reality. Finding that Higgs field will give us a more complete understanding about how the universe works. Most people think they know what mass is, but they understand only part of the story. For instance, an elephant is clearly bulkier and weighs more than an ant. Even in the absence of gravity, the elephant would have greater mass--it would be harder to push and set in motion. Obviously the elephant is more massive because it is made of...

Will scientists ever find the elusive Higgs particle, the last of the fundamental particles predicted by the Standard Model of particle physics and postulated to play a major role in how fundamental particles get their masses? Are there undiscovered particles "beyond" those described by the Standard Model? Experiments expected to begin next year at the Large Hadron Collider (LHC), a new particle accelerator at the European Center for Nuclear Research (CERN), will take up the search and explore other intriguing questions about matter in our universe. Ketevi Assamagan, a physicist at the U.S. Department of Energy's Brookhaven National Laboratory, has...

After decades of intensive effort by both experimental and theoretical physicists worldwide, a tiny particle with no charge, a very low mass and a lifetime much shorter than a nanosecond, dubbed the "axion," has now been detected by the University at Buffalo physicist who first suggested its existence in a little-read paper as early as 1974. The finding caps nearly three decades of research both by Piyare Jain, Ph.D., UB professor emeritus in the Department of Physics and lead investigator on the research, who works independently -- an anomaly in the field -- and by large groups of well-funded physicists...

Particle physics is in the doldrums. Since 1974 it has not made any major advance except to add to the particle zoo and to tweak the Standard Model. String theory has claimed the attention many young physicists, eager for both fresh challenges and new intellectual adventures. But save for a daunting set of equations, string theory to this day is devoid of even a scintilla of direct observational evidence. For these reasons, a lot is riding on the Large Hadron Collider (LHC) that was completed last year and will begin full operation this year... It's the world's biggest particle accelerator...

From the masses and interactions of other particles that we know exist, physicists calculated that the Higgs is most likely to have a mass (or energy) of around 80 gigaelectronvolts (GeV). If particle accelerators smash particles together at that energy or higher, it should be possible to make one. This is what members of the Electroweak Working Group at CERN were doing for the 5 years until LEP (the Large Electron Positron Collider) closed down last year. Since then they've been sifting through the data they gathered--and found nothing. They rule out most possible masses for the Higgs, including the...

A £2 billion project to answer some of the biggest mysteries of the universe has been delayed by months after scientists building it made basic errors in their mathematical calculations. The mistakes led to an explosion deep in the tunnel at the Cern particle accelerator complex near Geneva in Switzerland. It lifted a 20-ton magnet off its mountings, filling a tunnel with helium gas and forcing an evacuation. It means that 24 magnets located all around the 17-mile circular accelerator must now be stripped down and repaired or upgraded. The failure is a huge embarrassment for Fermilab, the American national...

British scientist Peter Higgs, whose work is the cornerstone of modern physics, said Monday he is putting champagne on ice in the hope a new experiment confirms his theories on how the universe works. Higgs, a veteran professor at Edinburgh University, told journalists in a rare interview that he hopes a vast experiment in the tunnels deep underground the CERN laboratory on the Franco-Swiss border could finally prove the existence of an elusive and unstable particle to which he has lent his name. The so-called "Higgs Boson" has been dubbed the 'God Particle' because so many have searched for it...

GENEVA -- Michelangelo L. Mangano, a respected particle physicist who helped discover the top quark in 1995, now spends most days trying to convince people that his new machine won't destroy the world. "If it were just crackpots, we could wave them away," the physicist said in an interview at the European Organization for Nuclear Research, known by its French acronym, CERN. "But some are real physicists."

Observations of the cosmic microwave background might deal blow to theory. The background patterns of space could help us focus on quantum problems.NASA / ESA / Hubble Heritage Team The question of whether quantum mechanics is correct could soon be settled by observing the sky -- and there are already tantalizing hints that the theory could be wrong. Antony Valentini, a physicist at Imperial College, London, wanted to devise a test that could separate quantum mechanics from one of its closest rivals -- a theory called bohmian mechanics. Despite being one of the most successful theories of physics, quantum mechanics...

European particle physics laboratory CERN is set to launch its gigantic experiment which hopes to throw light on the origins of the universe within a month, the laboratory's head said Tuesday. If things go according to plan, the greatest experiment in the history of particle physics could unveil a sub-atomic component, the Higgs Boson, known as "the God Particle." The "Higgs," named after the eminent British physicist, Peter Higgs, who first proposed it in 1964, would fill a gaping hole in the benchmark theory for understanding the physical cosmos. Other work on the so-called Large Hadron Collider (LHC) could explain...

The first particles have been injected into the biggest atom smasher on the planet, marking the start of the countdown to probing the secrets of the universe. Scientists are pushing ahead with powering up the machine, shrugging off speculative fears that it could destroy all life on Earth by sucking it into a black hole. Starting up the biggest scientific experiment ever built is not as simple as flipping a switch.

Correct calculation strengthens theory of quark-gluon interactions in nuclear particles When it comes to weighty matters, quarks and gluons rule the universe, a new study confirms. One of the largest computational efforts to calculate the masses of protons and neutrons shows that the standard model of particle physics predicts those masses with an uncertainty of less than 4 percent. Christian Hoelbling, affiliated with the Bergische Universtät Wuppertal in Germany, the Eötvös University in Budapest and the CNRS in Marseille, France, and his colleagues report their findings in the Nov. 21 Science. Nearly all the mass of ordinary matter consists of...

When the LHC first went down, it was believed that repairs could get the system up and running by April 2009. Then we saw repairs pushing the timeline back to summer 2009. But now, CERN has arrived at a fork in the road regarding LHC repairs. According to spokesperson James Gillies, the complicated repairs can be simplified into modest Plan A and Plan B approach. Plan A is a quick and dirty fix, getting the particle accelerator online as quickly as possible (late summer 2009) at the cost of operating at lower power. In this scenario, 3 of 8 pressure...

Europe's particle physics lab, Cern, is losing ground rapidly in the race to discover the elusive Higgs boson, or "God particle", its US rival claims. The particle, whose existence has been predicted by theoreticians, would help to explain why matter has mass. Finding the Higgs is a major goal of Cern's Large Hadron Collider (LHC). But the US Fermilab says the odds of its Tevatron accelerator detecting the famed particle first are now 50-50 at worst, and up to 96% at best. Both machines hope to see evidence of the Higgs by colliding sub-atomic matter at very high speeds. If...

CHICAGO (AFP) -- Physicists have come closer to finding the elusive "God Particle," which they hope could one day explain why particles have mass, the US Department of Energy's Fermi National Accelerator Laboratory announced Friday. Researchers at the Fermilab have managed to shrink the territory where the elusive Higgs Boson particle is expected to be found -- a discovery placing the American research institute ahead of its European rival in the race to discover one of the biggest prizes in physics. Physicists have long puzzled over how particles acquire mass. In 1964, a British physicist, Peter Higgs, came up with...

Same techniques could be used to detect theoretical particles like the Higgs boson Physicists have identified the production of the elusive single top quark, two research teams report. Previously top quarks have been observed only when produced in pairs, as when they were initially discovered 14 years ago at the Fermi National Accelerator Laboratory in Batavia, Ill. Now, researchers using Fermilab's two detectors announced March 9 that they have detected single top quarks. The techniques used to find the singleton quarks could help to identify other rare particles, such as the Higgs boson, the scientists say. "What a discovery," comments...

Two physicists speculate God -- or "time agents from the future" -- shut it down to keep them from discovering the God Particle. REPORTER'S NOTE: I've come across a lot of quirky articles in publishing intriguing news, but this rates up there with the most odd of all. What is odd, is that two such brilliant scientists would publicly proclaim their hypothesis that God not only exists, but interevened in their scientific endeavors. Wow. Not only that, but the addendum -- that it could have been God OR "time agents from the future" -- made me wonder. If these men were schooled in the divine supernatural, they may...

Rumours are emerging from the rival to the Large Hadron Collider that the Higgs boson, or so-called "God particle", has been found.
