Remnants of our digital discoveries are being dumped worldwide by the millions. After stripping off some valuable metal parts, the left overs are worthless. So called ‘Motherboards’, the main circuit board of a computer have a short life expectancy since new chips are developed with singularitarian speed*. When exposed to a variety of chemical liquids they become alive again. Never before I’ve seen so much beauty in discarded trash. Oil refineries and skyscrapers surround city grids which are overrun by unknown fungi and bacteria. The Russian artist Leonid Tsvetkov creates landscapes which could become ours in a not so distant future, or as he describes it himself: ‘My work focuses on reshaping cultural waste and exploration of social and physical processes. I am interested in the moments where the hard edge geometry of the city becomes organic or there random activity begins to take a highly organized form’.

(*) Technological singularity refers to the hypothetical future emergence of greater-than-human intelligence through technological means. Since the capabilities of such an intelligence would be difficult for an unaided human mind to comprehend, the occurrence of a technological singularity is seen as an intellectual event horizon, beyond which the future becomes difficult to understand or predict. Nevertheless, proponents of the singularity typically anticipate such an event to precede an “intelligence explosion”, wherein superintelligences design successive generations of increasingly powerful minds. The term was coined by science fiction writer Vernor Vinge, who argues that artificial intelligence, human biological enhancement or brain-computer interfaces could be possible causes of the singularity. The concept is popularized by futurists like Ray Kurzweil and it is expected by proponents to occur around 2045.

In his latest installation, “Seizure”, British artist Roger Hiorns has turned the idea of sculpture inside out. Rather than present a sculpture inside an architectural space, he’s turned every surface of the architectural space into sculpture. Mixing installation art and chemistry, he’s taken an entire abandoned apartment near London’s Elephant & Castle and transformed it into a gemstone. Covering the inside with blue copper sulphate crystals, he’s created an other-worldly, mineralized, glinting mirror of an everyday apartment. Jewels literally glowing from the ceiling and lining the floors…

The scale and production of “Seizure” is ambitious. After reinforcing the walls and ceiling and covering them in plastic sheeting, 80,000 litres of a copper sulphate solution was poured in from a hole in the ceiling. After a few weeks the temperature of the solution fell and the crystals began to grow. The remaining liquid was pumped back out and sent for special chemical recycling.

‘Caves are the earliest forms of dwelling and crystal caves do occur naturally in the form of salt and gypsum caves,’ Roger Hiorns says. ‘And in a way this project is converting a concrete modernist building into a cave. The work isn’t about architecture but there is that element of architectural reversion about it. Plus I am originally from Birmingham, so, for me, being surrounded by concrete is natural.’

Encased in ice-cooled orange suits, scientists explore the Cave of Crystals, discovered a thousand feet (304 meters) below Naica, Mexico, in 2000.

Like an old fashioned explorer Charley Reijnders wondered around on her self invented ‘Island of Products’ where a remarkable evolution took place after the disappearance of their human creators. Without any interference the new mechanical species evolved from the discarded mass consumer products of a long gone past. In a sketchbook she tried to capture all this new marvels of evolution.

According to Ray Kurzweil, the line between humans and machines will blur as machines attain human-level intelligence and humans start upgrading themselves with cybernetic implants. These implants will greatly enhance human cognitive and physical abilities, and allow direct interface between humans and machines.

‘Once life takes hold on a planet, we can consider the emergence of technology as inevitable. The ability to expand the reach of one’s physical capabilities, not to mention mental facilities, through technology is clearly useful for survival. Technology has enabled our subspecies to dominate its ecological niche. Technology requires two attributes of its creator: intelligence and the physical ability to manipulate the environment. This ability to use limited resources optimally, is inherently useful for survival, so it is favored. The ability to manipulate the environment is also useful; otherwise an organism is at the mercy of its environment for safety, food, and the satisfaction of its other needs. Sooner or later, an organism is bound to emerge with both attributes.

As technology is the continuation of evolution by other means, it shares the phenomenon of an exponentially quickening pace. The word is derived from the Greek tekhn¯e, which means “craft” or “art,” and logia, which means “the study of.” Thus one interpretation of technology is the study of crafting, in which crafting refers to the shaping of resources for a practical purpose.’ (abstract of Ray Kurzweils ‘The Age of Spiritual Machines’)

When a scientist states that something is possible, he is almost certainly right. When he states that something is impossible, he is very probably wrong. The only way of discovering the limits of the possible is to venture a little way past them into the impossible. Any sufficiently advanced technology is indistinguishable from magic.

Without a doubt, the single most important problem in physics and cosmology today is Dark Matter. Consider after all of the incredible advancements in science and technology in the 20th century, today, a decade into the 21st century, we still do not know what more than 96% of the universe is made of! Not a clue!

How is this possible when we are able to peer through powerful telescopes in spacetime back to the beginning of the universe, almost at the instant of the Big Bang, that we don’t know what constitutes most of the universe? It brings into question our concept of knowledge, the world, reality, our very being. What is this dark universe to which we belong yet without awareness for so long?

And yet, the world is even more marvelous than we can ever imagine. I present here only one of many theories of dark matter that is being studied by scientists today. It is one which I think is the simplest and the most elegant, called the Brans Conjecture, named after the general relativist, Carl Brans, who first conceived this theory in 1991. The Brans Conjecture explains dark matter as a phenomenon created by a topological property of spacetime called exotic smoothness. We shall explain these strange sounding terms shortly, but for now, the point is that there may not be any “real” dark matter at all according to Bran’s theory. Instead, just as Einstein told us that spacetime is curved by gravity, Brans is telling us that another geometric property of spacetime may be a new type of “smoothness”. When viewed from a part of spacetime with ordinary smoothness such as our own, the distant regions of spacetime with exotic smoothness will appear to have extra forces appearing as dark matter and dark energy.

What is smoothness? The Chinese word for smooth consists of two characters: 光滑. 光 means light , empty, free of things that can obstruct. 滑 means slippery, the three dashes on the left is the radical for water, and the character to the right is for “bone”. My interpretation is that the water makes the floor slippery so you can break your bone on it. Mathematically, this concept can be made very precise: something smooth can be locally approximated by flat surfaces, which is the “differential” – a linear approximation which forms the basis for calculus. Hence smooth objects are also known as “differentiable” and the smooth structure on a smooth object is called its “differential structure”.

Since the invention of calculus by Newton and Leibnitz, mathematicians have taken for granted that there is only one kind of “smoothness” or “differential structure” on an object of any dimension. These smooth regular objects are called manifolds, conceived and described first by Riemann in the early 19th  century. Ever since Descartes coordinatized space by “Cartesian Coordinates” like the regular grids of vertical Avenues and horizonal Streets used to coordinatize Midtown Manhattan (New Amsterdam), we think of N-dimensional space, called RN, as the set of points each with a lable [x1, x2, … xN] where x1 is the coordinate in the first dimension, x2 is the coordinate for the second, and so on.  From this point of view, there really isn’t that much difference between a 3D world coordinatized by [x1, x2, x3] and the 4D world coordinatized by [x1, x2, x3, x4]. You just add another coordinate and everything is more or less the same – or so it seems.

In reality, each dimension is an entirely different beast. Although coordinate-wise all dimensions look the same, [x1, x2, … xN], geometrically every dimension is different in its own way. The situation is so utterly fantastic that even mathematicians themselves had a hard time believing this phenomenon. In 1954, while researching the fabled “Poincaré Conjecture” to characterize the simplest manifold we know, the sphere, John Milnor chanced upon the discovery that S7, the 7-th dimensional sphere, had more than one smooth structure! He called these “exotic spheres”. In fact, there are exactly 28 different smooth structures on S7. More over, it is different in every dimension! The computation of the number of exotic structures in each dimension is very complicated involving Bernoulli numbers.

Now, you will notice from Table 1 that in every dimension from 1 to 20, the number of exotic spheres is known – except in dimension 4, the dimension of spacetime in which we live. This number is the famous “Smooth Poincaré Conjecture in Dimension 4” which is still an open problem. In fact, dimension 4 is truly unique in the context of exotic smoothness.

>  In every other dimension, exotic manifolds (high dimensional surfaces) can have only finite numbers of distinct exotic smooth structures. In dimension 4, every known exotic manifold has infinite number of exotic smooth structures.

>  In every other dimension, the N-dimensional Euclidean space, RN, given by the set of all coordinates { [x1, x2, … xN], where x1, x2, … xN is a real number}, has only one smooth structure. In dimension 4, RN has an uncountable number of smooth structures.

One cannot help but see that dimension 4 is truly unique in a way which we are still grasping to understand. These facts about exotic smoothness in dimension 4 were only discovered in the 1980’s.

As strange as the ideas of invisible dark matter/energy and exotic smoothness seem to us today, one day in the near future, we will understand what they are and how to manipulate matter, energy, and spacetime with these new concepts. Consider Einstein’s equation E = MC2 and the vast consequences it brought to the world, we cannot but sit up and pay attention when something so fundamental as our knowledge of the nature of matter has been put into doubt! What we think we know best, our material world, is now but a mere shadow of a vast universe we have absolutely no knowledge of. And we can’t even see it! It goes right through us, like phantoms and ghosts. We will turn our attention to the three key aspects in which these concepts touch our lives.

Dark matter cannot be directly observed since they reflect no light thus is completely dark. Hence the only way to detect it at the present is to infer its existence from the way it affects the motion of nearby ordinary matter which we can see. This is how it was discovered. While studying the Coma galaxy cluster in 1933, Fritz Zwicky first noticed that the motion of the cluster indicated there was missing mass in order to account for the faster velocities of the galaxies observed. He coined the term “Dark Matter” for this missing mass. It was not taken seriously at first until in the 1960’s Vera Rubin, using more sensitive instruments, was able to measure the velocities of stars in a galaxy with great precision. She expected stars at a distance further from the center of the galaxy would move slower according to Keplerian orbital theory. To her great surprise, she found all the stars in the galaxy have nearly the same velocties even for stars at the edge of the galaxy where they should move much more slowly. The current accepted theory is that this could only be explained by the existence of dark matter.

When we speak of dark matter and dark energy, there really are two distinct phenomena here. While dark matter is invisible matter in the universe, dark energy is a type of repulsive force causing an accelerated expansion of the universe. From the equivalence of mass and energy from Einstein’s famous equation, dark energy also forms a part of the mass energy of the Universe.

At the moment, exotic smoothness remains a mathematical curiosity without any physical expression or application. However, as we have noted the very unusual multiplicity of exotic manifolds in dimension 4, the dimension of our space-time, suggests that perhaps there are real physical expressions of this phenomenon. At the moment, the problem is that we don’t even know how to work with these exotic manifolds numerically. No one knows how to coordinatize exotic R4, the 4-dimensional Euclidean space, for instance. The standard coordinates [x1, x2, x3, x4] is not smooth for exotic R4’s. So when a 3D fluid is in motion, the 4D simulation object (here time is the 4th dimension) can reach singularities as in turbulence, wave breaking, etc. Is it possible that some of these effects can be described by a change in the smooth structure from the standard smoothness to an exotic smooth structure?

As to the philosophical implications, our species has been in existence on Earth for millennia, yet we are just beginning to discover that the solid real world is not what it seems. It is just 4% of the real Universe. This brings into question our sense of reality, of the solidness of the world, of material things. What is the reality of the other 96% of the Universe which we can neither see nor touch, of which we have absolutely no idea what is involved?  What is called into question is not the scientific method which continues to be one of the few lights we have to guide our way around the universe.

What is called into question is the hubris that we now know everything there is to know about the world. What is left unknown is just a few details to clean up our theory. But the Tree of Knowledge is much bigger than we can ever imagine. We see but a small branch and that through a glass dimly. For example, the mathematician Göedel showed that any logical system is incomplete. This great theorem means that if we start out with a set of assumptions (called axioms), there are statements we can make based on these assumptions which can neither be proven to be true or false within these assumption. This means our logic is inherently unable to solve all of our problems. What there is beyond logic is yet to be discovered.

Exotic Smoothness, like Dark Matter, was only discovered in the mid 20th century, a phenomenon which only occurs in dimensions 4 and higher. Whether or not this topological property of spacetime may explain Dark Matter or Dark Energy is not the main point of interest here. What is of interest here is the fact that, like our understanding of the material physical world, our mathematical concept of space is extremely limited by our 3D view of things. The world is a much stranger place than we can ever know or realize.

This should all make us question our materialistic point of view about the nature of reality. We should be more humble and open to other possibilities and other paths to knowledge. But, this is not a call to abandon rationalism or logic in any sense. Reason and logic are the only certain tools we have for dealing with reality. We must use them to discover and climb the other branches of the Tree of Knowledge. As to what these new tools beyond logic might be, I don’t have the slightest idea at the moment. But based on our experience with Dark Matter, our logical system may also represent only a small fraction (maybe 4%?) of various systematic methods to explore and understand the Universe. Intellectually, there may be a transcendental form of reasoning and method of knowing beyond Aristotelian logic yet to be discovered.The knowledge that comes to us through dreams and visions must be understood and interpreted properly. 20th century intelligentsia tended to treat this as inconsequential and bordering on superstitions. Given the waves of rising fundamentalism around the world, this is understandable. But this is a big mistake to think of the non-rational aspects of the psyche as irrational; it is transcendental. What we must achieve is to integrate the two aspects of our mind, the rational with the transcendental to become Whole as Jung would see it.

One person who has come up with an alternate method of knowing is Carl Jung and his theories of the Collective Unconscious and Synchronicity. This brings us to the world of human psyche, spirituality and religion. This also brings us to the world of art because in both these worlds, symbols play a key role. Truth may be expressed in symbolic form through dreams, visions, and art when words and equations are inadequate. As an illustration, I mention Plato’s Symposium where he explains what love is all about in one of the most profound and beautiful stories. Of course, this is not factual. It’s a parable. Surely even in ancient Greece no one believed in this story verbatim. It’s not meant to be factually true. And yet, when you read it, it touches a profound truth within you which delights you heart and makes you say “Oh, yes! That’s how it is. I fall in love when I find and recognize my missing half!” This truth about falling in love is very different from that of the chemistry of attraction and feromones. However, we need both. Neither is complete by itself. It must be integrated.

The knowledge that comes to us through dreams and visions must be understood and interpreted properly. 20th century intelligentsia tended to treat this as inconsequential and bordering on superstitions. Given the waves of rising fundamentalism around the world, this is understandable. But this is a big mistake to think of the non-rational aspects of the psyche as irrational; it is transcendental. What we must achieve is to integrate the two aspects of our mind, the rational with the transcendental to become Whole as Jung would see it.

The ideas about Dark Matter, Dark Energy, and Exotic Smoothness should shock us into realization that Reality is much more profound than the material world we know through our senses alone. We have by no means reached the end of the road so far as our knowledge of what Reality is all about.

Rinus Van de Velde uses signs as a means to put a recalcitrant reality in order. His starting point is shaped through the world of photographic representation. Having an extensive personal archive of images ranging from (semi)scientific magazines such as the National Geographic to biographies of artists and scientists, these images form a rich source for series of drawings in which the source material is still recognizably present. The resemblance between all these pictures is not so much what they show but how they show it. By using the photographs as material for a drawing and by situating it in a different context by adding text, Van de Velde ignores the facts and creates space to tell a personal story. The aim isn’t to tell the reality behind the photo but to create third degree myth. Many of the photographs that Van de Velde references are part of an ideology that isn’t completely right or which hasn’t survived the test of time: like the deep rooted faith in the myth of the artist as authentic or autonomous, scientific progress or paternal exotism. Instead of dismantling, Van de Velde weaves through text and reciprocally references a new story. The result is a sort of mirror-universe, inhabited by brave alter-egos that map the world around them and function as ideal representatives of the actual artist.

Small wooden sculpture, planed square on one side, the other is inflicted like a burned lump or black tumor, like a stick dipped in dark matter.

Consisting of sheets of paper tiled to represent an image of the moon, upon closer inspection, the design is made up of text that reads, “I Create as I Speak.” A single sheet is removed from the wall and rests on a lectern, with a microphone and a portable amplifier, inviting the viewer to interact with the work. The text plays with words; “I Create as I Speak” translates to ABRACADABRA in the ancient Aramaic language.

The existence of wormholes, shortcuts through spacetime, is still hotly debated.  Stephen Hawking gave a lecture touching on the possibility and the implications of traversable wormholes.  In theory, they would allow quick travel in space to even the most remote galaxies (you wouldn’t actually be travelling faster than the speed of light, but you would beat light to your destination, because it had to travel all the way around). More baffling still, they would allow time travel too. Hawking stated that if you could travel from one side of the galaxy to the other in a matter of a week or two, you could return through another wormhole, and be back before you started your journey. The theory only allows travel back in time, and only to the moment of the initial creation of the time machine.  Hawking again: a time machine will be built someday, but has not yet been built, so the tourists from the future cannot reach this far back in time.

Even weirder than dark matter—the invisible stuff constituting most of the mass of the universe—is dark energy, a mysterious force pushing the universe apart at an ever-faster rate. Dark energy has been around for most of the history of the cosmos. “Nine billion years ago, dark energy was already wielding its repulsive influence on the universe,” explains Johns Hopkins University astrophysicist Adam Riess. But the repulsion didn’t exceed the force of gravity until 5 billion years ago, when cosmic expansion kicked into high gear and began accelerating.

A pioneering space mission called the Wilkinson Microwave Anisotropy Probe (WMAP) delivered the first accurate account of the overall makeup of the universe. The answer is decidedly strange. Dark energy makes up 73 percent of the universe, dark matter another 23 percent. Atomic matter—everything around us and everything astronomers have ever seen—accounts for just 4  percent.

Comparing images from the Hubble Space Telescope’s high-end cameras with the WMAP heat signature map of the early universe, Riess and his colleagues retraced the growth history of the universe with unprecedented accuracy and depth. “It’s as if you mark the height of a child against a doorframe to measure growth spurts,” Riess says. For reasons as yet unknown, the antigravitational effects of dark energy are greater now than they were in the distant past. One theory, supported by the Hubble data, is that empty space is impregnated with residual energy from the Big Bang. As space expands, so does dark energy, while matter is spread out, weakening the inward pull of gravity.

Anish Kapoor is renowned for his enigmatic sculptural forms that permeate physical and psychological space. Most often, the intention is to engage the viewer, producing awe through their size and simple beauty, evoking mystery through the works’ dark cavities, tactility through their inviting surfaces, and fascination through their reflective facades. Throughout, he has explored what he sees as deep-rooted metaphysical polarities: presence and absence, being and non-being, place and non-place and the solid and the intangible. His most recent works are mirror-like, reflecting or distorting the viewer and surroundings.

Turning the World Inside Out II, 1995

In general relativity, the presence of matter (energy density) can curve spacetime, and the path of a light ray will be deflected as a result. This process is called gravitational lensing and in many cases can be described in analogy to the deflection of light by (e.g. glass) lenses in optics. Lensing measures all the mass, in particular the dark matter as well as the luminous matter.

There are ongoing searches to use lensing to find a type of dark matter called MACHOs (massive compact halo objects). Although MACHOs, as dark matter, cannot be seen themselves, if they pass in front of a source (e.g. a star nearby), they can cause the star to become brighter for a while, e.g. days or weeks. This effect has been observed but determinations of the dark matter are not yet conclusive.

Neutron stars are the cold, dense remnants of massive stars that died in fiery supernova explosions. They tend to have masses similar to the sun, but in diameter they would barely stretch 60km. This extreme density makes neutron stars exceptionally good nets for dark matter. For their size and their temperature, they have the best efficiency in capturing WIMPs (Weakly Interacting Massive Particles). Particles up to 100 times smaller than the ones underground experiments are sensitive to could still make a noticeable difference to neutron stars. Hunting for cold stellar corpses near the center of the galaxy or in star clusters could put new limits on the properties of dark matter.

Dark matter and ordinary matter are thought to clump up in some of the same places, like the center of the galaxy or globular clusters of stars. The center of the galaxy is dusty and difficult to observe, and most globular clusters are so far away that a cold, tiny neutron star hiding inside them would be beyond today’s telescopes. The next generation of ultraviolet telescopes could be up to the task.

Astronomer Bob Rutledge of McGill University suggests an alternative approach: Rather than squinting for neutron stars’ dim light, astronomers could find them through ripples in space-time called gravitational waves. When two neutron stars merge, they are expected to throw off massive amounts of these waves, and Earth-based detectors like LIGO are already in place to catch them — although no waves have actually shown up yet.

History of Darkness, 2010

History of Darkness is a slide archive; a life-long project, it will eventually contain hundreds upon thousands of images of darkness from different times/places in the history of the Universe, spanning billions of years. Each image handwritten with its distance from earth in light years, and arranged from one to infinity.

The Death Star below is a fictional moon-sized space station and superweapon appearing in the Star Wars movies and Expanded Universe.

Most cosmologists are convinced that the answer lies in physics theory, which predicts the existence of fundamental particles that have not yet been discovered. They are called Weakly Interacting Massive Particles, or WIMPs.

Dark matter (blue) passed through nearly unaffected after the head-on galactic
collision of 2006, while visible matter (red) slowed down and spread out. High-
energy electrons captured over Antarctica could reveal the presence of a nearby
but mysterious astrophysical object that's bombarding Earth with cosmic rays,
researchers say. Or the electrons may be the long-awaited physical evidence of
elusive dark matter. Either way, the unusual particles are exciting for astro-
physicists, who say they could someday confirm or deny decades of unproven
theories. (Credit: NASA)

A few exotic particles have been suggested as dark matter ingredients; the Kaluza-Klein particle, the Axion and the Neutralino. The most wanted particle however that might account for the missing matter is the Higgs boson particle, also known as the ‘God-particle’. The existence of the particle is postulated as a means of resolving inconsistencies in current theoretical physics, and attempts are being made to confirm the existence of the particle by experimentation, using the Large Hadron Collider (LHC) at CERN and the Tevatron at Fermilab.

The Higgs boson is the only Standard Model particle that has not been observed and is thought to be the mediator of mass. Experimental detection of the Higgs boson would help explain the origin of mass in the universe.

Both deep underground and high in sky scientists are attampting to capture the misterious dark matter particle.

A technique used by the Cryogenic Dark Matter Search (CDMS) detector at the Soudan Mine at Minnesota, US, relies on multiple very cold germanium  and silicon  crystals. The crystals (each about the size of a hockey puck) are cooled to about 50 millikelvins. A layer of metal (aluminium and tungsten) at the surfaces is used to detect a WIMP passing through the crystal.

One of the hocky-puck-size detectors used in the CDMS experiment.

DRIFT I was built by UK and US scientists to search for dark matter. DRIFT I ran between 2001 and 2004, 1.1 kilometres underground in Yorkshire’s Boulby Mine. It did not detect dark-matter particles, but its powerful successors continue the search.

In SNOLAB, a Canadian underground physics laboratory at a depth of 2 km in Sudbury, Ontario, scientists are conducting two experimental programs, LEAP-1 and PICASSO, in order to find the missing WIMPs.

At the Kamioka Observatory, Institute for Cosmic Ray Research a neutrino physics laboratory located underground in the Mozumi Mine of Hida in Gifu Prefecture, Japan, several studies are being carried out to find a WIMP. The particle detector is a cylindrical tank  which contains 3,000 tons of pure water and has about 1,000 50 cm  diameter photomultiplier tubes (PMTs) attached to the inner surface.

In 2016 the deepest research station DUSEL will become operational. The Deep Underground Science and Engineering Laboratory, or DUSEL  is a major project under consideration by the National Science Foundation. DUSEL will be a series of large laboratories, caverns, and cleanrooms  serving the field of underground science. The main impetus for DUSEL is the study of extremely rare nuclear physics processes, like neutrino scattering and dark matter interactions which can only be studied in the absence of cosmic rays.

In 2008 the Fermi Gamma Ray Space Telescope (GLAST) was launched into space in order to look for signs of new laws of physics and what composes the mysterious dark matter. This mision should complement the data coming from the Payload for Antimatter Matter Exploration and Light-nuclei Astrophysics (PAMELA) which was launched in 2006.

By the end of 2010, despite all the efforts, the mystery of the dark matter in the universe remains unsolved.

‘Infinite space within an infinite nothingness. Undefinable spirit within unlimited thought. Icons and insatiable quests. Human curiosity has a need for a context within which to exist. Religion was science as science is now religion. The justification of our lust and thrust for the infinite, away from our sensory paradise, comparable to the search for the deepest recesses of our minds, are both ways of seeking the answers to creation, purpose and demise. Religion, as a system of control, has come close to its great rival throughout history – the laws of physics that govern our universe. ‘When will miracles cease?’ – The modes of technology that we produce are ingenious to the children of earth but woefully inadequate adaptations of our unlimited imagination. ‘Why are we here?’ – Spiritual answers are equally unsatisfactory compared to the power of such simple questions. The answer may lie in convergence. Technology may have to wait for the power of the human brain to fully develop its (super)natural abilities. Will the technologies that are then produced be miraculous in that they may not require material substance to work but a faith, a belief in laws of physics so subtle than matter itself cannot withstand their logic? Will they be based in technology so discreet that it will be indistinguishable from the very fabric of the universe and all that is created within it? When we look at science and religion, are we looking at the same technology at different levels of evolution? Is humankind always to be polarised and thus paralysed?’ - Mark Baker -

The Large Hedron Collider

If you were to dig a hole 300 feet straight down from the center of the charming French village of Crozet, you’d pop into a setting that calls to mind the subterranean lair of one of those James Bond villains. A garishly lit tunnel ten feet in diameter curves away into the distance, interrupted every few miles by lofty chambers crammed with heavy steel structures, cables, pipes, wires, magnets, tubes, shafts, catwalks, and enigmatic gizmos.

This technological netherworld is one very big scientific instrument, specifically, a particle accelerator-an atomic peashooter more powerful than any ever built. It’s called the Large Hadron Collider, and its purpose is simple but ambitious: to crack the code of the physical world; to figure out what the universe is made of; in other words, to get to the very bottom of things.

There’s one puzzle piece in particular that physicists hope to pick out of the debris from the LHC’s high-energy collisions. Some call it the God particle.

The preferred name for the God particle among physicists is the Higgs boson, or the Higgs particle, or simply the Higgs, in honor of the University of Edinburgh physicist Peter Higgs, who proposed its existence more than 40 years ago. Most physicists believe that there must be a Higgs field that pervades all space; the Higgs particle would be the carrier of the field and would interact with other particles, sort of the way a Jedi knight in Star Wars is the carrier of the “force.” The Higgs is a crucial part of the standard model of particle physics—but no one’s ever found it. - Joel Achenbach -
