The Big Bang, the LHC and the Evolution of the Creation of the Universe by Brian Cox

In "There's probably no God, the Atheists Guide to Christmas" edited by Ariane Sherine, Brian Cox has a chapter on the Big Bang titled "The Large Hadron Collider: A scientific creation story".

The LHC recreates the conditions of the universe less than a billionth of a second after the big bang. The job of the LHC is too study the universe during the time when the Higgs particles are thought to have been generated. The history of the universe is thus:

• 13.7 billion years ago universe begins (t=0)
• gravity separates from the other forces of nature (t+10-43 seconds)
• exponential expansion of universe (t+10-36 s)
• from size of electron to size of melon (t+10-32 s)
• with formation of sub-atomic particles
• and Higgs field (t+10-12 s)
• gives mass to sub-atomic particles
• Higgs acts like cosmic treacle
• if Higgs particles aka Higgs Boson, aka The God Particle (Leon Lederman) exist (after 40 years we don't know) then Higgs Boson must be created in LHC (Standard Model)
• Higgs particles decays too quickly to be seen even in LHC 
• but Muon will be seen from decay of Higgs particle 
• Higgs Boson is tens or hundreds of times heavier than the protons that were smashed together (mini big bang) to create it (E=mc2). Energy=mass
• because Higgs particles are light enough to show up in LHC
• if Higgs particles are NOT found in LHC 
• some other mechanism (Minimally Supersymetric Standard Model?) will show up in LHC which creates mass
• and explains Dark Matter

After t+10-12 s time we already know what happened to the universe because smaller cousins to LHC (eg Fermilab Tevatron?) have been working for decades:-

• 4 forces of nature (strong nuclear, electromagnetic, weak, gravity) formed (t+10-6 s)
• strong nuclear force
• binds quarks together in nucleus of atom
• electromagnetism
• holds electrons in place around nucleus
• weak force
• allows sun to shine, explains radioactive decay
• gravity
• is missing from Standard model
• creates infinities when gravity is added 
• if treat particles as tiny points, when they come infinitely close together, gravity becomes infinitely strong 
• by treating particles as strings (not tiny points) we have a way for gravity to work
• but gravity is included in Einstein's General Relativity
• a Theory of Everything would combine Standard model with General Relativity
• String Theory combines all particles and forces (and makes a decent cup of coffee!)
• quarks and leptons interact
• quarks stick together to give protons & neutrons, neutrinos roam universe (t+1 s)
• protons & neutrons form elements (t+3 minutes)
• Hydrogen 75% : Helium 25% ratio fixed (t+30 m)
• Light as Photons set free from dense universe: cosmic microwave background (t+ 380,000 years)
• gravity collapses H & He to form stars
• 4 forces of nature interact: x3 He fuse to give Carbon
• more fusions give oxygen and other light elements
• stars run out of fuel, explode 
• scattering C & Oxygen & other light elements
• creating Gold, Silver & other heavy elements
• gravity forms stars & dense rocky planets orbit
• on at least one planet, occurs self replication & life & us!

Talks Brian Cox: What went wrong at the LHC

The Big Bang Machine

Professor Brian Cox visits Geneva to take a look around Cern's Large Hadron Collider before this vast, 27km long machine is sealed-off and the experiment to create the simulation of a black hole begins. 

When it's up and running, it will be capable of creating the conditions that existed just a billionth of a second after the Big Bang. Brian joins the scientists who hope that the LHC will change our understanding of the early universe and solve some of its mysteries.

Broadcast on:

BBC Four, 9:00pm Thursday 4th September

Duration:

60 minutes

Available until:

9:59pm Thursday 11th September

Mysteries of the Universe will be solved, starting next Wednesday

Source: The Times.

Beneath the foothills of the Jura mountains, in a network of tunnels that bring to mind the lair of a crazed Bond villain, scientists will fire a first beam of particles around a ring as long as the Circle Line on the London Underground. This colossal circuit, 17 miles (27km) in circumference,

In the years ahead it will recreate the high-energy conditions that existed one trillionth of a second after the big bang. In doing so, it should solve many of the most enduring mysteries of the Universe.

This extraordinary feat of engineering will accelerate two streams of protons to within 99.9999991 per cent of the speed of light, so that they complete 11,245 17-mile laps in a single second. The two streams will collide, at four points, with the energy of two aircraft carriers sailing into each other at 11 knots, inside detectors so vast that one is housed in a cavern that could enclose the nave of Westminster Abbey.

The mountains of data produced will shed light on some of the toughest questions in physics. The origin of mass, the workings of gravity, the existence of extra dimensions and the nature of the 95 per cent of the Universe that cannot be seen will all be examined. Perhaps the biggest prize of all is the “God particle” – the Higgs boson.

“What we find honestly depends on what’s there,” said Brian Cox, of the University of Manchester, an investigator on one of the four detectors, named Atlas. “I don’t believe there’s ever been a machine like this, that’s guaranteed to deliver. We know it will discover exciting things. We just don’t know what they are yet.”

“The beam is 2mm in diameter and has to be threaded into a vacuum pipe the size of a 50p piece around a 27km loop,” said Lyn Evans, the LHC’s project manager, who will oversee the insertion. “It is not going to be trivial.”

Questions and Answers

Professor Brian Cox answers questions sent in by the audience about CERN's new Large Hadron Collider and the major experiment which is planned to be launched on the 10 september 2008. Do you have a question? Ask expert Brian Cox anything about the project and read his responses to other questions.

QWhy experiment at all?
Can you tell me why we are doing this experiment? I can understand that you are hoping to reveal the origins of mass by smashing tiny particles together but what advantages (besides increase in knowledge), do you expect to obtain from this?
Stephen

A Experiment is the basis of the scientific method, without which there would be no modern world as we know it. The quest to understand the smallest building blocks of nature and the forces that hold them together arguably began with the ancient Greeks, but it was only when we began to conduct experiments that we discovered the electron (1897), quantum mechanics (triggered by precision observations of the light emitted by elements when heated), X-rays, the atomic nucleus, radioactive decay ..... the list is practically endless. Without these experimental discoveries, and the subsequent deepening of our understanding of the Universe, there would be no electronics, no silicon chips or transistors, no medical imaging technology, no nuclear power stations, no X-rays or chemotherapy treatments for cancer .... again an almost endless list. What this should teach us is two things. First, it is virtually impossible to deepen our understanding of nature without experiments. Second, understanding nature has never been a bad idea - indeed without the pioneers of the past century our civilisation would be immeasurably poorer. I do not know what the continuation of this long and illustrious quest will lead to, but I would be extremely surprised if a writer called upon to defend scientific enquiry at the turn of the 22nd century does not point to the LHC as the foundation of a hundred new technologies, each considered essential to our quality of life.

Q Existence of Multi-Dimensions
Will the Collider be able to prove to scientists that many other dimensions exist as well as ours? If so, then what will the implications be for our future, and could this be a good explanation for the many UFO sightings around the world.
Ian

AThe LHC could indeed provide strong evidence for the existence of extra dimensions in our Universe. The fact that they are so hard to see (if they exist), however, means that our world interacts with them very weakly. In fact, we theorize that if they do exist, the force of gravity is the only influence that can pass between them. This would prevent any material objects from crossing from one set of dimensions to another. So no, UFO enthusiasts must look elsewhere.
BC

Q Understanding Dark Matter
Will the LHC help our understanding of Dark Matter (which seems to make up most of the Universe) and Dark Energy (which seems to be accelerating the expansion of the Universe)? Are these phenomena 'real' or just a result of our misinterpreting measurements of distance and mass for far away objects
Russell

AQuite possibly, yes, certainly for the case of dark matter. One of the most popular interpretations of the evidence that points to the existence of dark matter is that there are new, as yet undiscovered heavy particles in the Universe that interact with normal matter only via the weak nuclear force and gravity. In particle physics, we have a family of theoretical candidates for such particles known as Supersymmetric particles. If these exist, then many theoretical physicists expect them to be made and discovered at the LHC. Dark energy is another mater, because we have very little theoretical understanding of this phenomena at present. It may just be that if we get some evidence of extra dimensions at the LHC, which may point the way to a deeper understanding of gravity (a "quantum theory of gravity" along the lines of string theory perhaps), then we may gain some insight into this fascinating discovery.

And yes, you are correct that these phenomena may be due to a mis-undertstanding of something - perhaps the theory of gravity itself at very large distance scales. I think the experimental evidence that something is missing in our understanding is very strong now, however, and its not merely an experimental error. .
BC

Q Multiple Big Bangs
What are the possibilities of multiple Big Bangs creating multiple parallel universes?
Jon

AIf you're asking about the mini-big bangs at the LHC, then the chances are zero. It's a bit of a misnomer actually to call the collisions mini Big Bangs - each one has the energy of a mosquito hitting you in the face on a summers day, albeit confined to a very small space!

But - and this has little to do with LH directly - some of the current theories of the origin of our Universe suggest that in fact the Universe has been around for ever. What we see as the big bang was simply something happening to our little piece of spacetime 13.7 billion years ago. There could be multiple "sheets" of spacetime (sometimes called "branes" floating around in an infinitely large multi-dimensional Universe, with everything we see being confined to just one. When these sheets bump into each other, they become very hot and expand, so to anyone living on a sheet today it would look like their Universe began at the point of collision.
BC

Q Black Holes and matter
If you are able to generate even small Black Holes, will they suck up matter? Do full sized Black Holes draw in invisible matter also? You have an exciting project and I wish you a lot of luck in the operation of your new hardware.
Merlin

AIt's just possible that we could create mini black holes, although this would require at least that there are extra dimensions in our Universe, for which we have no evidence ! If, however, we did, then the little black holes would bear no relation at all to the Black Holes created when stars collapse. They would evaporate away very quickly via a process called Hawking radiation (unless we have no understanding at all of quantum theory). Even if they don't, they would be so very tiny that matter would never get close enough to them to be sucked in! Big black holes do suck matter in, and should also emit Hawking radiation, although they emit it much more slowly and so live for a very long time (much more than the current age of the Universe).
BC

Q Applications to everyday life
In terms off what this could achieve for the humanity in the next 20-30 years. Can this technology change our everyday lives within our lifetimes? Or do you see humanity waiting a little more patiently before our lives are transformed with wormholes and quantum computing?
Lawrence

AI wish I knew! Let me give one positive example from history. Quantum mechanics was developed to maturity as a theory during the 1920s and by 1947 we had the first transistor. It is often said, I think with some justification, that it is extremely unlikely that transistors could have been developed without the quantum theory. Perhaps we are on the verge of a similar leap when we deepen our understanding of the sub-atomic world once again at LHC - who knows!
BC

Q New forms of fuel?
Do you think that there is a chance of discovering a new fuel source or better ways to create/manage energy during this experiment? I imagine enormous amounts of energy coming out of it...
Dave

ANo energy comes out of LHC - we get out of every collision exactly what we put in. I think the best hope for LHC technology helping us with the energy crisis is that the cooling systems developed for LHC are now being transfered to the ITER fusion project in France. And fusion certainly would be the answer to our energy problems if we can make it work on an industrial scale, which is the goal of ITER by around 2035.
BC

Q What if the Higgs Boson particle is found?
I also understand that the purpose of the LHC is to find the elusive God particle. If this was found, what would be the implications for science as we know it, and what would the next steps be?
Darren

AThe Higgs particle is one of our theoretical explanations for the origin lf mass in the Universe. If found, therefore, we will understand what mass is! This is the place where we are "stuck" at the moment in our theories, and answering this question will we suspect provide a door to a deeper understanding of the Universe. If the Higgs theory is wrong, by the way, then we will see whatever it is that is responsible for generating mass - it doesn't HAVE to be a Higgs particle! The implications are quite profound because this is the point at which our current best theory of reality, the Standard Model, breaks down. We have been stuck here for several decades, so the LHC is guaranteed to be a giant leap forwrad whatever we find there.
BC

Q What if there is no Higgs Boson?
What will it mean if the Higgs Boson and other particles are not detected by the LHC?
Alex

ASee above ! It will be more exciting in many ways because it will mean that we have understood much less than we thought about nature.
BC

Q Can bacteria survive?
Would it be possible to put various simple bacteria into the experiment to see if it survives. We are relatively certain that plant RNA probably evolved during the big bang. Animal DNA on the other hand could not and possibly came from meteorites carrying bacteria from other worlds (Panspermia theory). It would put this idea to bed if it couldn't survive the big bang.
Mick

AIt won't! At the temperatures we generate in the collisions at LHC even protons and neutrons don't survive, never mind atoms and molecules.
BC

Q Safety Concerns
CERN have been confident in the prediction that there are no major risks associated with the LHC's operation. How robust is this prediction? In particular, how reliant is it upon unsupported theoretical assumptions?
Chris

I have heard that there is a very small possibility that this experiment could go wrong and create a black hole that could be catastrophic, is this actually possible?
Chris

Okay, so how do we know this thing won't make planet Earth implode then?
Stephen

Why would scientists want to risk the planet in this way? It is of course fascinating to want to know how the big bang worked but what is the point if our world was destroyed? Nobody will be around to find out the answer or if the experiment was successful or not. I am not being alarmist I just think that any risk is a risk too much. I and my precious family wish to be around on this beautiful planet for a long while.
Pam

ALet me answer all of these at once.

The LHC has absolutely no chance of destroying anything bigger than a few protons, let alone the Earth. This is not based on theoretical assumptions.

It is, of course, essential that all scientific research at the frontiers of knowledge, from genetics to particle physics, is subjected to the most rigorous scrutiny to ensure that our voyages into the unknown do not result in unforeseen, perhaps dangerous outcomes. CERN, and indeed all research establishments, do this routinely and to the satisfaction of their host governments. In the case of the LHC, a report in plain English is available here:

http://public.web.cern.ch/public/en/LHC/Safety-en.html

For the record, the LHC collides particles together at energies far below those naturally occurring in many places in the Universe, including the upper atmosphere of our planet every second of every day. If the LHC can produce micro black holes, for example, then nature is doing it right now by smashing ultra-high energy cosmic ray particles into the Earth directly above our heads with no discernable consequences. The overwhelmingly most likely explanation for our continued existence in the face of this potentially prolific production of black holes is that they aren’t produced at all because there are either no extra dimensions in the Universe, or they aren’t set up right for us to see them. If black holes are being produced, then next on the list of explanations for our continued existence is the broad theoretical consensus that sub-atomic black holes should fizzle back into the Universe very quickly billionths of a second after they are created in a little flash of particles via a process known as Hawking radiation. In other words they evaporate away very quickly indeed. This process, which is perhaps Steven Hawking’s greatest contribution to theoretical physics, is on significantly firmer theoretical ground than the extra dimensions theories required to create the little black holes in the first place. Even if Hawking is wrong, and therefore much of our understanding of modern physics is also wrong, the little black holes would be so tiny that they would rarely come close enough to a particle of matter in the Earth to eat it and grow. And even if you don’t buy any of this, then you can still relax in the knowledge that we have no evidence anywhere in the Universe of a little black hole eating anything – not just Earth but the Sun and planets and every star we can see in the sky including the immensely dense neutron stars and white dwarfs, remnants of ancient Suns that populate the sky in their millions and which because of their density would make great black hole food.

So - the only theoretical bit is in the proposition that you can make little black holes in the first place. From then on, observation tells us that these things either (a) don't exist - the most likely explanation, or (b) exist but do not eat neutron stars and are therefore harmless, probably because they evaporate away very quickly indeed!

I am in fact immensely irritated by the conspiracy theorists who spread this nonsense around and try to scare people. This non-story is symptomatic of a larger mistrust in science, particularly in the US, which includes intelligent design amongst other things. The only serious issue is why so many people who don't have the time or inclination to discover for themselves why this stuff is total crap have to be exposed to the opinions of these half-wits.

Q The Original Big Bang
May I ask, how do you know that there was a "Big Bang" in the first place, surely it's all just guess work and speculation.
Andrew

What instigated that first big bang? Surely there need be something to have caused it? Is it a cop out to say that first cause is transcendent or just the best possible answer?
Christopher

I watched a program with Stephen Hawkins and he said that before the "Big Bang" there was nothing, if there was nothing, then where did everything come from...?
Andrew

A See above for a discussion of possible alternative theories for theBig Bang.
