Quantum physics and consciousness

Today was the day of connecting with inner self. So I spent the afternoon going through some books on consciousness and its connection with quantum physics.

For more than two hundred years Newton’s ideas dictated our world view. Newton declared that everything operates mechanically and can be predicted like clockwork. Science in Newton’s view, being nothing more than the act of observing, meant that this world view was easily perpetuated by independent observers all over the world.

In the late 19th century, science entered into the era of subatomic physics, which changed everything. Scientists discovered that the so-called ‘subatomic particles’ were not particles at all. They behaved like particles when they were measured but they traveled like waves. Quantum theory has changed everything, because what was once a mechanical, external universe has now become a web of intelligence. Science finally admits that the simple act of observing changes the result of any experiment and by extension, that the observer and the observed are not separate.

Quantum physics started in the late nineteenth century and is associated with the work of German physicist Max Planck. In the 1890's Planck set out to explain the phenomenon of blackbody radiation; the observation that the color of light emitted from an object did not change in a linear fashion to its temperature. Planck provided an explanation for the phenomenon in 1900 by postulating that light is emitted or absorbed in packets of definite size, which he called a quanta. Thus light, once considered a wave, was now being described as a particle (photon) in order to solve the riddle of blackbody radiation.

Quantum theory is also generally regarded as one of the most successful scientific theories ever formulated. But while the mathematical description of the quantum world allows the probabilities of experimental results to be calculated with a high degree of accuracy, there is no consensus on what it means in conceptual terms. The issues involved with this apparent conceptual conundrum are discussed in this article by David Pratt - Consciousness, Causality, and Quantum Physics.

According to physicist Leon Lederman there are three qualities we know about quantum theory.

1. It is counterintuitive,
2. It works,
3. It has problems.

Lederman goes on to write, "In spite of the great practical and intellectual success of quantum theory, we cannot be sure we know what the theory means." It is this ambiguity within the "hard" science of physics that has helped initiate a crisis unlike science has ever encountered. Once concerned with the motion and trajectory of particles, physics is now considering questions which would have been labeled as blasphemy throughout academic circles a hundred years ago. Now, numerous physicists are speculating about the nature of reality, the existence of consciousness, even the existence of God.

According to Pratt - According to the conventional interpretation of quantum physics not only is it impossible for us to measure a particle's position and momentum simultaneously with equal precision, a particle does not possess well-defined properties when it is not interacting with a measuring instrument. Furthermore, the uncertainty principle implies that a particle can never be at rest, but is subject to constant fluctuations even when no measurement is taking place, and these fluctuations are assumed to have no causes at all.

Simply speaking, the quantum world is believed to be characterized by absolute indeterminism, intrinsic ambiguity, and irreducible lawlessness. Most physicists are content to accept the assumption of absolute chance. This has important implications in connection with free will.

As the late physicist David Bohm (1984, p. 87) put it: "it is assumed that in any particular experiment, the precise result that will be obtained is completely arbitrary in the sense that it has no relationship whatever to anything else that exists in the world or that ever has existed."

It is widely accepted that consciousness or, more generally, mental activity is in some way correlated to the behavior of the material brain. Since quantum theory is the most fundamental theory of matter that is currently available, it is a legitimate question to ask whether quantum theory can help us to understand consciousness. Several approaches answering this question affirmatively, proposed in recent decades, have been surveyed in this excellent article - Quantum Approaches to Consciousness.

According to Mark Bancroft in Quantum Physics & Consciousness - "Quantum physics has directly challenged the meaning of matter for more than fifty years. Being defined as, "Something that occupies space and can be perceived by one or more senses; a physical body, a physical substance, or the universe as a whole.” Thus, matter may also mean the entire universe; including "'not-real' stuff". The atom was considered to be the indivisible building block of the universe up until the discovery of the electron. Now, particle physicists postulate that there are sixty-one elementary particles which make up all matter in the universe."

On a side track - Professor of Mathematical Physics, Frank Tipler, confidently proclaims that physics can and will lead to the immortality of humankind. He shares on page three of his book - The Physics of Immortality.

According to Dream Manifesto - Reality is never experienced on an exclusively personal level. The 21st century has witnessed the introduction of new ideas about how we fundamentally view reality. However, all we can know of the world in an absolute sense comes from our own sensory perceptions and the mental constructions we build around them. Behind these perceptions lies pure consciousness. Quantum physicists have shown that consciousness itself - something you have in infinite supply - is the basic stuff of the entire universe.

Quantum physics is a branch of physics which concerns itself with the study (observation) of the subatomic realm. Physics is defined as, "The science of matter and energy and of interactions between the two. Physical properties, interactions, processes, or laws. The study of the natural or material world and phenomenon." Being a scientific endeavor the above definition appears to fit with the somewhat vague definition of science.

A rather beautiful representation of quantum mechanics and consciousness is given on this website…

And before I close this entry, I must mention Fred Alan Wolf who is a physicist, writer, and lecturer who earned his Ph.D. in theoretical physics at UCLA in 1963. He continues to write, lecture throughout the world, and conduct research on the relationship of quantum physics to consciousness. He is the National Book Award Winning author of taking the Quantum Leap. He is a member of the Martin Luther King, Jr. Collegium of Scholars. More can be found about him on this blog… of course he also has his own blog site J there are a thousand questions which clamor my mind and one day, I intend to ask Dr. Quantum…

What is time?

"The most exciting phrase to hear in science, the one that heralds new discoveries, is not 'Eureka!' (I found it!) But 'That's funny ..." Isaac Asimov

As I sit on a Sunday morning, pondering about fast the weekend went by and how less the time seems to be when you are having fun… a thought struck me – what is time? Often the immediate concept that comes to mind is a clock, watch or a calendar, but what really is time?

According to John Sankey, to physicists, time is defined by quantum mechanics. A photon with energy h (Planck's constant) behaves as though it were oscillating once per second. Modern atomic clocks are based on this. Time direction is something else. It is based on information, which sits uneasily in the world of physics. But, any quantum system must have an arrow of time.

You often hear: “I have no time.”, “Time is money.”, “I need to be on time” and so on.

I have read through some scientific literature and what the scientific community considers as time if even more confusing than our everyday common sense notions about it, for example the Einstein theory of relativity makes the subject for ordinary people just even more confused.

What if time were to stop?

As L. Ron Hubbard (1951) had put it - The illusion called time is composed of altering of the particles position in space” and “Alteration is the basic manifestation of time. Well, he was much more of fantasy novel writer than actual scientist (some may dispute the fact).

Everything moves, all the time. Time is measured from instruments which from beginning come from natural movements such as the sun and the planet as well as the moon. When we think of time we tend to think of the ways in which we measure the passing of time, such as a clock or watch, or perhaps a measured interval of time such as an hour or minute, but not of time itself. So what is time? Exactly what is it that we are measuring?

We can begin to answer the question with the basic description that we are measuring the interval between events, using units that we have chosen for the purpose. We may say, for example, that the next train will be due in 5 minutes. While this information may be very useful for telling us how late the train is when it eventually arrives, it does nothing to describe just what it is that we are measuring. We want to know exactly what the 'interval' is.

Time can seem as solid as a rock. In fact, it's a lot more squishy. Our calendars are imperfect. We need a leap day to keep them in line with the seasons, and even so, time will eventually get away from us. "If you feel there aren't enough hours in a day, just wait," says Max Tegmark, a cosmologist at the Massachusetts Institute of Technology. "In a few hundred million years, tidal friction will have slowed Earth's rotation to make the day 25 hours long."

If that doesn't make your head spin, consider that in physics, motion alters time; in psychology, different stimuli alter our perception of time; and in philosophy, there's disagreement on whether time is even real. "In terms of our inner lives, no time exists except for what is happening in the present moment," says Joan Halifax Roshi, a Zen Buddhist teacher.

Whew!

And I thought time was such a simple matter to ponder about…

In physics and other sciences, time is considered one of the few fundamental quantities. Time is used to define other quantities – such as velocity – and defining time in terms of such quantities would result in circularity of definition. An operational definition of time, wherein one says that observing a certain number of repetitions of one or another standard cyclical event (such as the passage of a free-swinging pendulum) constitutes one standard unit such as the second, is highly useful in the conduct of both advanced experiments and everyday affairs of life. The operational definition leaves aside the question whether there is something called time, apart from the counting activity just mentioned, that flows and that can be measured. Investigations of a single continuum called space-time brings the nature of time into association with related questions into the nature of space, questions that have their roots in the works of early students of natural philosophy.

Among prominent philosophers, there are two distinct viewpoints on time.

One view is that time is part of the fundamental structure of the universe, a dimension in which events occur in sequence. Time travel, in this view, becomes a possibility as other "times" persist like frames of a film strip, spread out across the time line. Sir Isaac Newton subscribed to this realist view, and hence it is sometimes referred to as Newtonian time.

The opposing view is that time does not refer to any kind of "container" that events and objects "move through", nor to any entity that "flows", but that it is instead part of a fundamental intellectual structure (together with space and number) within which humans sequence and compare events. This second view, in the tradition of Gottfried Leibniz and Immanuel Kant, holds that time is neither an event nor a thing, and thus is not itself measurable nor can it be traveled.

According to Lee Smolin, The debate between absolute and relational time echoes down the history of physics and philosophy, and confronts us now, at the end of the twentieth century, as we try to understand what notion of space and time is to replace Newton's. If there is no absolute time, then Newton's laws of motion don't make sense. What must replace them has to be a different kind of law that can make sense if one measures time by any clock. That is, what is required is a democratic rather than an autocratic law, in which any clock's time, imperfect as it may be, is as good as any other's. Leibniz was never able to invent such a law. But Einstein did, and it is indeed one of the great achievements of his theory of general relativity that a way was found to express the laws of motion so that they make sense whichever clock one uses to embody them with meaning. Paradoxically, this is done by eliminating any reference to time from the basic equations of the theory. The result is that time cannot be spoken about generally or abstractly; we can only describe how the universe changes in time if we first tell the theory exactly which real physical processes are to be used as clocks to measure the passage of time.

The problem is that general relativity is only half of the revolution of twentieth-century physics, for there is also the quantum theory. And quantum theory, which was originally developed to explain the properties of atoms and molecules, took over completely Newton's notion of an absolute ideal time.

So, in theoretical physics, we have at present not one theory of nature but two theories: relativity and quantum mechanics, and they are based on two different notions of time.

“In the theory of relativity, the concept of time begins with the Big Bang the same way as parallels of latitude begin at the North Pole. You cannot go further north than the North Pole,” says Kari Enqvist, Professor of Cosmology.

One of the most peculiar qualities of time is the fact that it is measured by motion and it also becomes evident through motion.

According to the general theory of relativity, the development of space may result in the collapse of the universe. All matter would shrink into a tiny dot again, which would end the concept of time as we know it.

No general agreements here, although the search for the grand unified theory is on the achievement does not appear to be any closer still.

There is of course, like anything else under the purview of human thought, an alternate, more human approach towards time…

Spiritual guide and alternative medicine expert Deepak Chopra, who warned of the dangers of a hectic lifestyle. "People who feel that they are 'running out of time' have speeded up their biological clocks," says Chopra. "They have faster heart rates and jittery platelets with high levels of adrenaline. When they drop dead from a premature heart attack, they have literally 'run out of time.'"

Perhaps the most surprising thing we heard about time came from a scientist and entrepreneur who studies aging. "Time has little impact on biology," says Michael West, a gerontologist who teaches at the University of California, Berkeley, and founded the biotech company Geron. That sounds reassuring at first--but it's only because we're pre-programmed to fall apart anyway. "From a gerontologist's standpoint, biological time is not wear-and-tear, it's a genetic program," says West. "It's sort of like a time bomb. The cells are programmed to last just long enough for us to rear children, and no longer."

If now is both now and forever, as C.S. Lewis suggested, then the religious view may not be so different than the scientific view. Physics tells us that all moments exist equally, at once--it's only our consciousness that distinguishes the present from the past or future.

According to The Internet Encyclopedia of Philosophy, “Time has been studied by philosophers and scientists for 2,500 years, and thanks to this attention it is much better understood today. Nevertheless, many issues remain to be resolved. Here is a short list of the most important ones—what time actually is; whether time exists when nothing is changing; what kinds of time travel are possible; why time has an arrow; whether the future and past are real; how to analyze the metaphor of time's flow; whether the future will be infinite; whether there was time before the Big Bang; whether tensed or tenseless concepts are semantically basic; what is the proper formalism or logic for capturing the special role that time plays in reasoning; and what are the neural mechanisms that account for our experience of time”.

There are 3 competing theories:

--> Presentists argue that necessarily only present objects and present experiences are real, and we conscious beings recognize this in the special "vividness" of our present experience

--> According to the growing-universe or growing-block theory, the past and present are both real, but the future is not because the future is indeterminate or merely potential

--> The third and more popular theory is that there are no significant ontological differences among present, past and future because the differences are merely subjective. This view is called "the block universe theory" or "eternalism."

Although there are theories of how to solve a specific problem about time, it is always better to knit together solutions to several problems. Ideally, the goal is to produce a theory of time that will solve in a systematic way the constellation of problems involving time. What are those problems?

--> One is to clarify the relationship between time and the mind. Does time exist for beings that have no minds? It is easy to confuse time itself with the perception of time.

--> Another problem is to decide which of our intuitions about time should be retained. Some of these intuitions may reflect deep insights into the nature of time, and others may be faulty ideas inherited from our predecessors. It is not obvious which is which. For one example, if we have the intuition that time flows, but our science implies otherwise, then which view should get priority? Philosophers of time must solve the problem of how to treat our intuitions

--> A third problem for a philosophical theory of time is to clarify what physical science presupposes and implies about time. Most all philosophers of time claim that philosophical theories should be consistent with physical science, or, if not, then they must accept the heavy burden of proof to justify the inconsistency

A philosophical theory of time should describe the relationship between instants and events. Does the instant that we label as "11:01 A.M." for a certain date exist independently of the events that occur then? In other words, can time exist if no event is happening? This question or problem raises the thorny metaphysical issue of absolute vs. relational theories of time.

The article is profound in its depth and I strongly recommend reading, though not on a Sunday afternoon, when one is more attuned towards a lazy stroll through time rather than an activity which challenges the one’s intellect and imagination both.

Although we understand that Time is a component of a measuring system used to sequence events, to compare the durations of events and the intervals between them, and to quantify the motions of objects, Time has been a major subject of religion, philosophy, and science, but defining time in a non-controversial manner applicable to all fields of study has consistently eluded the greatest scholars. Also, throughout my readings, the concept of time, which we all take for granted, is still far from being agreed upon by most of the branches of human thought from Physics to religion. It is profoundly disturbing and humbling to know that we know how to split an atom, reach the moon and gaze at the depth of cosmos, we are still not quite sure what time is… although we can experience its effects on everything we see around us…

The GOD Particle!

In my last entry, I talked about the LHC or Large Hadron collider. One of the mission parameters of building the LHC was to find clues to or discover outright the Higgs Boson – also popularly titled the God Particle.

According to Wikipedia article – “The Higgs boson or BEH Mechanism, popularized as the "God Particle", is a hypothetical massive scalar elementary particle predicted to exist by the Standard Model of particle physics; it is the only Standard Model particle not yet observed. Experimental observation would elucidate how otherwise massless elementary particles nevertheless manage to construct mass in matter. More specifically, the Higgs boson would explain the difference between the massless photon and the relatively massive W and Z bosons. Elementary particle masses, and the differences between electromagnetism (caused by the photon) and the weak force (caused by the W and Z bosons), are critical to many aspects of the structure of microscopic (and hence macroscopic) matter; thus, if it exists, the Higgs boson is an integral and pervasive component of the material world. “

As of yet, no experiment has directly detected the existence of the Higgs boson, but this may change as the Large Hadron Collider (LHC) at CERN produces results.

Did all the information given above make any sense to you? Okay, you are not alone in having a significant challenge in understanding what elementary particle physics to scientists is literally these days J. Alright, let’s go back to the basics here.

Get physicists and cosmologists talking about their work and they will tell you that there are elegant theories and messy ones. Almost all of them believe the universe conforms to an elegant one. A central goal of today's physics, in fact, is to show that at its very beginning, the universe was ordered and unified. But this unity didn't last for long. Just instants after the Big Bang, as the explosion cooled and its contents scattered, the cosmos' forces and matter differentiated. The universe fell from a state of perfect grace into its current complexity, in a cosmic parallel to Adam and Eve.

Many great minds — Democritus, Isaac Newton, James Clerk Maxwell, and Albert Einstein — took giant steps toward bringing the universe's lost unity out of hiding. In 1964, Peter Higgs, a shy scientist in Edinburgh, added his name to that list by coming up with an ingenious theory that gave scientists the tools to explain how two classes of particles, which now appear to be different, were once one and the same. His theory proposes the existence of a single particle responsible for imparting mass to all things — a speck so precious it has comes to be known as the "God particle." The scientific term for it is the Higgs boson, and to find it physicists are counting on the most powerful particle accelerator ever constructed: the Large Hadron Collider (LHC) at the CERN laboratory in Geneva, a 17-mile underground circuit that took 25 years to plan and $6 billion to build

Basically, all the known forces in the universe are manifestations of four fundamental forces, the strong, electromagnetic, weak, and gravitational forces. But why four? Why not just one master force? Those who joined the quest for a single unified master force declared that the first step toward unification had been achieved with the discovery of the discovery of the W and Z particles, the intermediate vector bosons, in 1983. This brought experimental verification of particles whose prediction had already contributed to the Nobel Prize awarded to Weinberg, Salam, and Glashow in 1979. Combining the weak and electromagnetic forces into a unified "electroweak" force, these great advances in both theory and experiment provide encouragement for moving on to the next step, the "grand unification" necessary to include the strong interaction.

One rather comic and more understandable (at least to the masses) explanation of what Higgs Boson is all about are given here. In 1993, the UK Science Minister, William Waldegrave, challenged physicists to produce an answer that would fit on one page to the question 'What is the Higgs boson, and why do we want to find it?' The winning entries can be found here.

As usual in all things related to human discoveries, there is a rumor flying around that the so called God Particle may have already been found at the Tevatron, an accelerator located outside of Chicago. This isn't the first time a story like this has circulated. Until the LHC opens, the Tevatron remains the largest accelerator in the world. Among its most significant past discoveries is another standard-model particle, the top quark. And in 2009, it will shut its doors forever. Like the LHC, the Tevatron was built with the Higgs in mind, and as time runs out for America's biggest atom smasher, some nervy experimentalists have jumped the gun. The full text of this article can be found here.

For those who like to have a little more technical details on the whole matter (pun intendedJ) can access the articles at Hyperphysics. And like everything else, human capacity for trivializing the profound and thus making it less frightening to masses has been equally at work for Higgs Boson as well. You can find “music” inspired by the god particle at the so called edge of science at the official site of Higgs Boson!

The Higgs boson has appeared in several works of fiction in popular culture. These references rarely reflect the expected properties of the hypothetical elementary particle, or do so only vaguely and often imbue it with fantastic properties. The curious and long list of such fiction works can be accessed via this article!

There is more serious stuff at the scientific American on the questions related to Higgs Boson.

All the theories apart, to me the search for this ultimate particle is part of the overall quest of humankind to understand itself and its origins. We are, after all, made of star stuff. All that constitutes us was once manufactured in the nuclear furnaces of old and giant stars scattered throughout the cosmos. I find this quest irresistible.

Next, I’ll be talking about the wave-particle duality… watch out for this space :-)

Doomsday Machine –Large Hadron Collider (LHC): Is end of the world near?

As the Large Hadron Collider (LHC) nears completion and commissioning, there are wild talks and even protests about its potential impact on the world and the universe in general.

But what is LHC and what is the reason behind the human Endeavour to build a machine such as this or monstrosity as it is being called by some.

As put in science daily – “Particle colliders creating black holes that could devour the Earth. Sounds like a great Hollywood script. But, according to UC Santa Barbara Physics Professor Steve Giddings, it's pure fiction”.

So come, explore with me the conundrum behind arguably perhaps the greatest scientific effort by humankind and I really say human kind and not an individual since this work is being conducted by an international team – making it a truly human Endeavour rather than a work of a single intellectual giant like Einstein, Newton, etc… The LHC is the world's largest and the highest-energy particle accelerator. It is funded and built in collaboration with over eight thousand physicists from over eighty-five countries as well as hundreds of universities and laboratories.

What is Large Hadron Collider or LHC?

The Large Hadron Collider (LHC) is a gigantic scientific instrument near Geneva, where it spans the border between Switzerland and France about 100 m underground and is being built in a circular tunnel 27 km in circumference. The tunnel is buried around 50 to 175 m. underground. It straddles the Swiss and French borders on the outskirts of Geneva. It is a particle accelerator used by physicists to study the smallest known particles – the fundamental building blocks of all things. It will revolutionize our understanding, from the minuscule world deep within atoms to the vastness of the Universe.

The idea of the Large Hadron Collider (LHC) began in the early 1980s. The first approval of the project by the CERN Council occurred in December 1994 and the first civil engineering construction work began in April 1998.

You can take a photo tour of LHC by clicking here

There is another very good collection of LHC related photographs at the Big Picture.

A graphical display of all components of LHC can be found here.

Complete workings of LHC can be found at CERN Site.

Why is LHC needed?

If we are to believe the scientists – this is all related to unfinished business of Newton and perhaps Einstein as well. Newton told us what the effects of gravitation are and how to calculate the effects. But told nothing about the nature of gravity – what is it after all and what causes it?

Einstein went a step further and combined Space and time. And then went on to explain gravity as the after effect of large mass curving space-time. This is all fine, but it still doesn’t tell us what gives us mass at all?

And it is here that we ask the crucial question - What is the origin of mass? Why do tiny particles weigh the amount they do? Why do some particles have no mass at all? At present, there are no established answers to these questions. The most likely explanation may be found in the Higgs boson, a key undiscovered particle that is essential for the Standard Model to work. First hypothesized in 1964, it has yet to be observed. The ATLAS and CMS experiments will be actively searching for signs of this elusive particle.

Everything we see in the Universe, from an ant to a galaxy, is made up of ordinary particles. These are collectively referred to as matter, forming 4% of the Universe. Dark matter and dark energy are believed to make up the remaining proportion, but they are incredibly difficult to detect and study, other than through the gravitational forces they exert. Investigating the nature of dark matter and dark energy is one of the biggest challenges today in the fields of particle physics and cosmology.

What does this machine do? Well, in LHC, two beams of subatomic particles called 'hadrons' – either protons or lead ions – will travel in opposite directions inside the circular accelerator, gaining energy with every lap. Physicists will use the LHC to recreate the conditions just after the Big Bang, by colliding the two beams head-on at very high energy. Teams of physicists from around the world will analyze the particles created in the collisions using special detectors in a number of experiments dedicated to the LHC

When activated, it is theorized that the LHC - collider will produce the elusive Higgs boson, the observation of which could confirm the predictions and missing links in the Standard Model of physics and could explain, as I mentioned earlier, how other elementary particles acquire properties such as mass. The verification of the existence of the Higgs boson would be a significant step in the search for a Grand Unified Theory, which seeks to unify three of the four known fundamental forces: electromagnetism, the strong nuclear force and the weak nuclear force, leaving out only gravity.

The Higgs boson may also help to explain why gravitation is so weak compared to the other three forces. In addition to the Higgs boson, other theorized particles, models and states might be produced, and for some searches are planned, including super symmetric particles, compositeness (Technicolor), extra dimensions, strangelets, micro black holes and magnetic monopoles.

The ATLAS and CMS experiments will look for super symmetric particles to test a likely hypothesis for the make-up of dark matter.

It will also help us in explaining the bias found in nature of matter over anti-matter. More specifically, it will help us in answering as to why there is no anti-matter. We live in a world of matter – everything in the Universe, including ourselves, is made of matter. Antimatter is like a twin version of matter, but with opposite electric charge. At the birth of the Universe, equal amounts of matter and antimatter should have been produced in the Big Bang. But when matter and antimatter particles meet, they annihilate each other, transforming into energy. Somehow, a tiny fraction of matter must have survived to form the Universe we live in today, with hardly any antimatter left. Why does Nature appear to have this bias for matter over antimatter?

The LHCb experiment will be looking for differences between matter and antimatter to help answer this question. Previous experiments have already observed a tiny behavioral difference, but what has been seen so far is not nearly enough to account for the apparent matter–antimatter imbalance in the Universe.

I’ll be writing more about the Higgs Boson or the “GOD PARTICLE” in my next entry. But if you are interested in reading more about it – follow this link.

It will also help us in answering whether there are other hidden dimensions. We are able to sense the common 3-dimensions and now with the help of Einstein also – time. Einstein showed that the three dimensions of space are related to time. Subsequent theories propose that further hidden dimensions of space may exist; for example, string theory implies that there are additional spatial dimensions yet to be observed. These may become detectable at very high energies, so data from all the detectors will be carefully analyzed to look for signs of extra dimensions.

So what’s the problem?

Okay, it sounds pretty fancy stuff, but hardly the case for paranoia being displayed by some groups of scientists and merrily being covered by our usual sensationalist media :-)

The main problem with the whole project is - Nobody knows for sure what is going to happen (off course there are several theories that are being tested).

Of course there is wide agreement that one of the sub products could be small black holes (tiny, mini, and minuscule). after that, most scientists (by most here I mean almost everyone in the planet) believe that, if these black holes happen to exist, they would “disappear” due to a series of very complicated reasons or, if they stay, it would take them several billion years before they grow to “eat” the earth.

A quite small number of scientists (allegedly 1 or 2 or the groups surrounding them), believes that this black holes would grow and fast, so they would end eating the earth in 50 months and, although the probability is not easily quantified, does the gravity of the potential result deserves to put the experiment on hold until a proper discussion takes places within the scientific community?

The concerns of this group were understood and addressed by CERN and dismissed. CERN actually used the research of Professor Steve Giddings, of UC Santa Barbara. Giddings has co-authored a paper documenting his study of the safety of microscopic black holes that might possibly be produced by the Large Hadron Collider (LHC), which is nearing completion in Europe. The paper, co-authored by Michelangelo Mangano of the European Center for Nuclear Research (CERN), which is building the world's largest particle collider, investigates hypothesized behavior of tiny black holes that might be created by high-energy collisions in the CERN particle accelerator.

As quoted in Science daily - The Giddings/Mangano study concludes that such microscopic black holes would be harmless. In fact, he added, nature is continuously creating LHC-like collisions when much higher-energy cosmic rays collide with the Earth's atmosphere, with the Sun, and with other objects such as white dwarfs and neutron stars. If such collisions posed a danger, the consequences for Earth or these astronomical objects would have become evident already, Giddings said.

Two major lawsuits have been initiated and quashed as far as I can understand (remember, I am not a lawyer either). One in the European Court of Human Rights and other in the US Federal District Court in Honolulu. The first sought an emergency injunction based on the experiment violating the right to life of European citizens and pose a threat to the rule of law, and the second tried to force the U.S. government to withdraw its participation in the experiment. It is important to note that the European Court of Human Rights rejected the request for the injunction but will hear the case (after the experiment has started). The status of US case is unknown at this moment.

Personally, I do not think that LHC is a threat to universe and humanity. Personally, I think it is a great conceit on humanity’s part if we think collectively that building a 27 km long tunnel and smashing a few atoms can trigger a universal collapse back to the state which existed prior to Big Bang. Although I am not a qualified high energy physicist, I do recall a similar scare during the time of the Manhattan Project – or the A-Bomb project of USA during 1940’s. At that time also, nobody was sure of what would happen when an atomic bomb went off. There were wild theories – mostly in public media and imagination and the most fanciful one that I recall is related to whole of earth’s atmosphere being burned off due to chain reaction set off by the exploding bomb.

Of course it never happened that way – our presence here is a testimony to that.

I do, however, acknowledge this hullaballoo as a classic case of failure of science to communicate to the masses. The media is doing what it does usually – sensationalizing the issue beyond reason.

Let’s look forward to a new era in scientific break through and new understandings of our reality as well new technologies. Remember – there wouldn’t TV if not for quantum mechanics, No GPS if not for Einstein and Newton!
